I just did this replacement yesterday on my 2door 97 Blazer. Nothing wrong with the old injectors just felt like replacing it. Now I have the original as a spare if the new one doesn't hold up. Much obliged for the help.
If I don t use my car for a week or so, I have problem cranking it. Sometimes it need 15, 20 cranks for the car to start. Is it the problem?. Seems that the gaz is not pushing in well.
@@backwoodzcustomz1549 Greetings. And the pressure of the fuel cell does not affect. (PCI) It is the same gasoline pressure of the 2nd generation and this 3rd Generation.
@@Huannt58 hey man, not sure if you got help with this, but this is an in-tank fuel pump issue, there is a check valve that stops fuel from going back to the tank, and when it sits, all the fuel runs back to the tank and the fuel pump has to bring it all the way to the motor. So it sounds like youd need a new fuel pump and filter while you're at it.
Got my 1998 Chevy Blazer in the shop now for this exact same problem. Got 202,000 miles out of the original spider injectors, and out of the fuel pump as well. Replacing both of them. Your video is a great description on how to do this job.
@@backwoodzcustomz1549can you convert these to a carburetor? My Spyder is hot and they want a lot to replace it. It's a 96 with about 178k. I can get an intake and 500 cfm carb for about 800 bucks. Is this possible?
@@backwoodzcustomz1549 it's I a five speed. I'm planning on a v8 swap. Not an ls maybe a big block but probably just a small block. I'm conflicted on spending the money to fix it or just save for the swap. I plan on putting an automatic in it anyway. Thanks for the help.
God Bless you for pointing out the fact that the taps had to go down on the fuel lines. Of the 6+ vids that I watched you are the only one showing this fact. I put them in wrong the firast time and drove to town, MISTAKE!!!!!!!!!!!!!!!!!!!!!!!!
This was a good one. I came here to see the spider connector get removed because I'm doing intake gaskets tomorrow and didn't want to break it.....because that...would be bad and the new gaskets are blue so you know they're good🤣 Now you know who else I watch.
Great video! I have a 1996 GMC Jimmy 4.3L 4x2. It would start fine in the morning, but had extended cranking within 10 or 15 minutes after it was shut off. Eventually, we took it to the dealer and they found that it was the fuel spider/regulator and replaced them. Not cheap...wish I'd seen this video before taking it in.
Having a hard time getting those nozzles in. Put motor oil on the tips and still can't. Don't want to use excessive force and breaking something. Any suggestions? Great video, thank you
I just replaced the o'rings in mine and had the same issue. I ended up having to take the lines off and slightly bending the return line where it goes into the spider. You should be able to eyeball it to get it close. You'll have to remove the distributor cap, the bolt that holds the fuel lines bracket to the engine, and the fuel line nuts to get it out.
Update: I had to remove the white injector nozzles, installed them on ports first, and then connected the fuel injectors onto them..all good now. Thank you
Thanks for sharing. Good pointers. --- For a 2000 GMC V6, 4.3 L, does anyone know the typical reliable life of the fuel pressure regulator; and the typical reliable life of the fuel injector / poppits ? Would it be wise to replace the fuel injector / poppits assembly after 200k miles?
just check trims at idle, low single digits, negative and positive numbers.. two banks.(these engines are smart as heck, dual trim). look for the occasional 9-10 trim while it is skipping, this verifies one bad injector. 20 would be two, most likely stall then. I killed one with weld smoke (long story - open fuel filler tube in the smoke) I do not like the wires in vacuum, but it is up to you. I stayed original poppets, just new. two ways to kill these, this video has stuff that was simply old ready to replace. Mine was fairly new, and i killed one by other means. Replaced the whole set.
I did this some time ago, actually right after I got my blazer, and before I drove it enough to be at all familiar with it. Do I need a tune after this? Isn't this making it a more multiport injection system, and should give more power and get better gas mileage, as far as being more efficient. I get horrible mileage! Lol kinda hoping that a tune after is recommended and I just never did it
Blazers all get horribly fuel mileage.. they make way to little power for the size vehicle it's in.. you don't need a tune, it's just like changing an alternator...
97 silverado..new cap wires,plugs,coil,ign module,,fuel filter,.fuel pressure is good..compression test good on all cylinders..#8cyl misfire..truck sat long time bad fuel..drained the tank added fuel treatment still misfire at idle..you think the next thing would be replacing the spider injection??..
@@larrynflorida7517 it went well, it took me 2 weeks because i did a lot more since i had the dog houses off, conversion vans have 2, i also replaced plugs wires, cap rotor, coil and duel pump, i needed to have a flat line since i didnt get any repair records with it when i bought it, with 196k on it and it runs perfect!
THANKS GUYS. I WAS HAVING TROUBLE GETTING THE FUEL METER INTO THE HOUSING, CLEANING AND LUBE ON BOTH THE O RING AND THE PLENUM SLID IN LIKE RON JEREMY.
I just did to my 99 Silverado. Thanks to you guys she runs again. I just have a few questions. I never had water in the oil. After I did this I drove to town and checked the oil. It was brown and my truck said low coolant. My question is. If I did not put a new gasket on when replacing the spider pump. Will that cause water to be in the oil or is that not possible. Or did I some how busy my head gasket? Any idea . Please any info helps.
always use new gaskets when possible on a big job like this. i would go to the parts store and buy/rent a block tester and block test fluid. this basically tells you if you have exhaust gas in your coolant. it's possible now that you are making the proper power/ combustion pressure you popped a head gasket.
I'm in Nigeria, I have a Chevy Astro 2002, so much in love with her, getting parts here in Lagos is almost impossible and the spider injectors bn a whole lot of issues for me, can't even get a new one here and still love my van, may you help in getting one and how much is that gonna cost? Nice job there!👍
Bought one on Ebay. If you get the one I got for your S10, you may have to use your old bracket. The new one was too short, the plug just barely wouldn't clear the plenum and would not allow plug and clip.
Hi, I have a question 'cause I may be did not catch the reason for spider replacement. Was the spider the reason of a hard start? Did the engine work with old spider if you fired it up with the cold start spray? many thanks in advance
You can test both the check valve and spider injector by removing the upper manifold , reattaching the metal lines then feeding 50 to 60 psi air into them with a gauge attached. If it loses pressure on the spider side the regulator is bad , if you hear air rushing into in the gas tank side the check valve is bad . The new style injector is improved but the push in tabs are one time use and cost as much as $5 each , in short don't try and remove it once it's installed .
I haven't tried the starting fluid on the intake.I replaced the spider a couple years ago i have spark and fuel holds 60 psi .was wondering is there a way to test the spider cause that thing is $$ to buy again lol like to test is there actual fuel spraying out of each nozzle?
@@Rekairbrush By testing both lines with air you are testing both the check valve and the fuel pressure regulator which are the parts that typically go bad in this setup. Using some sort of spray in the injector will tell you if you are getting fuel to the engine in the first place.
Is there a bracket that holds the fuel lines down going to intake or just the nuts? I heard something fly off and fall when disconnecting i thought. Lol
I have a 98 blazer with 103,000 miles, I purchased at 102,750 miles and the car has started stalling around 55-70 mph on the way home from work. I have to pull over and restart the car and then it stalls again 1.5 miles later all the way home. Could a bad spider cause this? I’ve changed alternator, spark plugs, wires, distributor cap, rotor, new map sensor. I removed the throttle body, Idle air control and gave it a deep clean, I also cleaned out the MAF sensor. I have not test drove it yet after cleaning the throttle body, IAC and MAF sensor
@@backwoodzcustomz1549 it was deteriorated vacuum lines, they disintegrated in my hands when I grabbed them and a failing fuel pump. 1300$ later and I found the problems 🤦🏽♂️ car is running smooth now
@@backwoodzcustomz1549 I replaced the alternator, spark plugs and wires, distributor cap and rotor, map sensor, removed and completely cleaned the throttle body, idle air control valve, fuel filter, vacuum lines, and fuel pump. I broke the vent valve on the fuel tank when I was replacing the fuel pump, and it started throwing a p0446 code for a gas leak. Had to go to pick and pull to pull a gas tank because they don’t sell the original plastic tanks anymore and my new fuel pump was specifically for the plastic tanks not the metal tanks. What a headache it has been.
if it's your first time, i'd give it a weekend. but if all you have is water just drain the tank and throw in some water remover and hope for the best.
How do you modify the spider injector to feed a 5.7 vortec with headers, Lt4 Hotcam. This just a basic description of the engine I have planned for my 96 Silverado std Cab short bed. I see these new retrofit injectors that get rid of poppets and are 36lbs. But they are like $600!!! I want to mod a junkyard spider system thats in good shape to be able to perform at 36lbs and rid the poppet style to the new improved spider setup. What do I need to do and where do I go to learn the mod?
This is the best type of injection and not poppet's, get the ones with the wires running down to the injectors. It's not a big job I did mine 8 years ago before the new style. Maybe I'll get some, 96 350 has 311,000 and runs like a champ , at idle you have to look at the tack to tell if it's running 175 lbs per hole 3/4 quort in 3,000 miles
I replaced with the new style injector fails after 2 months hose rupture. Left me on the side of the road. I ended up putting Rebuilt Old style injector I bought on eBay. no problems after that oem is better.
Hey I have an 05 Chevy Express 1500 i did a spider injector replace on it. But for some reason the fuel feed line keeps popping out and then I get a puddle coming out from the bottom. How ca I fix that?
I’m having issues with my 96 blazer giving me a “check gages” message then it just dies out. I can start it again right away and it will be good for a few miles then do it all over again. Could a bad spider injector cause that to happen?
Ive had 3 of these new spiders in the last 4 weeks and it keeps losing number 7 and number 6 injector pulses Every time I fix one the other stops working. I have an updated fuel relay thats designed for both regular and flex fuel injectors so im not sure if that has anything to do with it or not. But it dont seem to bother the old style spider. Only the new ones My truck has been down for almost two weeks since installing the most recent new set. if i cant figure out whats going on i may be going back to the old spider very soon
Gentlemen I currently hand an issue with my chevy 4.3l spider injector wiring involving some squirrel chew of the wires. Could you possibly send me a wire color and position of the module or a high detailed picture showing the colors?
It would most likely cause codes to set off, but they would be errors as a result of a faulty injector harness. Maybe a particular cylinder or two that are misfiring. Maybe random multiple cylinder misfire. For a faulty pressure regulator, you can hookup a gauge to the access port against the firewall, and you can see the pressure decrease rate. A faulty injector harness usually also results in surging rpm, stumble on acceleration, maybe a gas smell from exhaust or high numbers of long and short term fuel trims. I ended up getting an O2 sensor code bc my faulty injector harness ran for so long with a rich fuel ratio it burned out the sensor early.
@@backwoodzcustomz1549 Thank you. Im at 145k and Im trying to do as much preventative maintenance. Already took care of everything in the bottom end. New chain timing even
The customer supplies this 1.. But i think you can get the for around $100. You will also need an upper intake gasket set.. Depending on what your shop charges an hour.. Your looking at like $500-700 i would say.
Hey my truck started then shut off. Checked for furl it has fuel all the way to the top of intake into spider injectors. Is there anyway to check if it's the injectors or the sensor that tells it to send fuel. It runs when sprayed with starting fluid
Well just cause it has fuel doeant mean its the right pressure so you should make sure the pressure is what it should be at the testing port with a fuel gauge
Checked pressure. It's got good pressure it drove fine went to store started it up to leave then it just died and wouldn't crank back have great pressure all the way up into top of intake/ spider injectors.
Most of the time the biggest issue with bad injectors is hard starts. You said yours started then shut off.. So best is to find out if yiur missing spark or fuel. Then go from there..
today i tried to change my injectors. it was hard to install with hard plastics line. I finally put everything back together, and now my truck is running extremely rough, and misfiring.
@@backwoodzcustomz1549 update. spider was bad. i brought it back, and got a new one. I put the new one on, changed the spark plugs, and boom truck running better than when it was new. Drove it for a few days, went outside one morning, and now it doesnt want to start at all.
@@backwoodzcustomz1549 I’m almost to that point…replaced it again last night just in case the part was a defective one. It was, misfire went away. Also wanted to check the plug on the misfired cylinder and ended up ripping the plug. So 2 spider units, new plugs, wires, and a throttle body pressure sensor and boom! Just like that, the original problem still isn’t fixed
@@backwoodzcustomz1549 agreed. It’s a shame I love that truck so much. Running up on 250k miles and the only issue is occasionally turns over for a min or 2 before it starts
If your good..3-4 hours..if not 5-6..but it’s just r n r ..keep track of what comes off so reinstall goes easy for you..clean the throttle body good and the mass air flow 😎
BACKWOODZ CUSTOMZ 15 how about random misfire code p0300. It seems to idle fine but under soft easy acceleration it backfires and misses and after you get to running speed 55-60 and hold it steady it backfires and misses but if you accelerate hard and fast it revs up no misses or anything also when going 55ish and stomp down it just takes off and goes no problem.
Read the injector install info really carefully there are 2 injector wire you have to route unconventionally or the plenum will never go back on. I know you prob already figured it out but posting for others trying to service it in the present. 😊
if your leaking fuel out the back of an engine, i would look at the fittings where the return and feed connect to this, or something got rusty, but i think the lines are stainless..

Cost dif is about 200.00. Appreciate any info. Yeah, it's nice they got rid of poppet set up. Those vales are notorious for failing. My 99 Yukon has 203K on it and after a tune up it's still misfiring with no codes. Thanks for any help!
@@freedomkeeper8003 i mean, ac delco is no longer an oem supplier for gm... They seperated many years back. You need to figure out if its an ignition or fuel missfire.. Also could have coolant leaking in the cylinder... I use nothing but the cheapest china parts i can find.. I have lityle to no issues... There is only like 5 manufactures of autoparts.. Most are just relabled boxes...

Had to go to pick and pull to pull a gas tank because they don’t sell the original plastic tanks anymore and my new fuel pump was specifically for the plastic tanks not the metal tanks. What a headache it has been.
@@Ghostacc956 good
Thanks for the vid, guys. It really helped.
Awesome... Glad to help..
Great work Guys, thanks for the upload!
Thanks for watching I hope it helped!!!
Excellent video
Thank you very much!
How long does it take to replace the spider on a 98 2500 Chevy pickup with 5.7 ?
It looks like somehow water got into the fuel system .
if it's your first time, i'd give it a weekend. but if all you have is water just drain the tank and throw in some water remover and hope for the best.
@@backwoodzcustomz1549
Thank you
do you really have to remove the coolant hose to the thermostat? I didn't think that was attached to the upper intake plenum.
You can do things however you like.
Id say it was simply to give more room to work in.
Anyone know what the torque specs are for the fuel line nuts on top of the spider?
I eventually found it. 27 lb. in. in case anyone else would like to know
How do you modify the spider injector to feed a 5.7 vortec with headers, Lt4 Hotcam. This just a basic description of the engine I have planned for my 96 Silverado std Cab short bed. I see these new retrofit injectors that get rid of poppets and are 36lbs. But they are like $600!!! I want to mod a junkyard spider system thats in good shape to be able to perform at 36lbs and rid the poppet style to the new improved spider setup. What do I need to do and where do I go to learn the mod?
In all honesty just do an ls swap....
Thanks man
This is the best type of injection and not poppet's, get the ones with the wires running down to the injectors.
It's not a big job I did mine 8 years ago before the new style. Maybe I'll get some, 96 350 has 311,000 and runs like a champ , at idle you have to look at the tack to tell if it's running 175 lbs per hole 3/4 quort in 3,000 miles
Out of 4.3 it might be the best... Deff not overall though...
I'm not up on my 4.7 stuff.. usually chrysler runs both...
I replaced with the new style injector fails after 2 months hose rupture. Left me on the side of the road. I ended up putting Rebuilt Old style injector I bought on eBay. no problems after that oem is better.
To each is their own.. sometimes people have different luck....
How does your fuel spider line move mine dont just like yours and it's has glue so it does not move
Never saw a glued one... I would say just keep at it..
Will a bad spider cause engine to stall and only start with gas pedal down
Possibly... When you put the gas pedal down it puts the car in fload clear mode... Which basically shuts off the fuel..
Can i replace the spider in my 1998 s10 with one off a 2008 both are 4.3 but the new one doesnt have a return line thanks
I'm not sure what would be all involved with that..
Hey I have an 05 Chevy Express 1500 i did a spider injector replace on it. But for some reason the fuel feed line keeps popping out and then I get a puddle coming out from the bottom. How ca I fix that?
Find out why it's doing it
How's the spider holding up still running good
Yup great
I’m having issues with my 96 blazer giving me a “check gages” message then it just dies out. I can start it again right away and it will be good for a few miles then do it all over again. Could a bad spider injector cause that to happen?
Could be anything...
crank sensor? had the same symptoms
Ive had 3 of these new spiders in the last 4 weeks and it keeps losing number 7 and number 6 injector pulses
Every time I fix one the other stops working.
I have an updated fuel relay thats designed for both regular and flex fuel injectors so im not sure if that has anything to do with it or not.
But it dont seem to bother the old style spider. Only the new ones
My truck has been down for almost two weeks since installing the most recent new set.
if i cant figure out whats going on i may be going back to the old spider very soon
it's a really bad design, not sure who thought it would be great lol.
Gentlemen I currently hand an issue with my chevy 4.3l spider injector wiring involving some squirrel chew of the wires. Could you possibly send me a wire color and position of the module or a high detailed picture showing the colors?
all i got is what you can see in the video. it was a customers car.
great video good job you saved me 600 in labor
Glad we could help....
Does the engine light come on for a bad regulator or spider injector?
It would most likely cause codes to set off, but they would be errors as a result of a faulty injector harness. Maybe a particular cylinder or two that are misfiring. Maybe random multiple cylinder misfire. For a faulty pressure regulator, you can hookup a gauge to the access port against the firewall, and you can see the pressure decrease rate. A faulty injector harness usually also results in surging rpm, stumble on acceleration, maybe a gas smell from exhaust or high numbers of long and short term fuel trims. I ended up getting an O2 sensor code bc my faulty injector harness ran for so long with a rich fuel ratio it burned out the sensor early.
@@evanrobinson7657 thank you for your insight
should pick up a misfire.
@@backwoodzcustomz1549 Thank you. Im at 145k and Im trying to do as much preventative maintenance. Already took care of everything in the bottom end. New chain timing even
You guys were awesome thanks
Just glad to help..
What was the cost of replacing spiders? Parts and labor if nothing else needs replaced to go back together ? Approx.
The customer supplies this 1.. But i think you can get the for around $100. You will also need an upper intake gasket set.. Depending on what your shop charges an hour.. Your looking at like $500-700 i would say.
Ok Thanks ! And your video was very helpful. Thanks for recording and sharing it.
Hey my truck started then shut off. Checked for furl it has fuel all the way to the top of intake into spider injectors. Is there anyway to check if it's the injectors or the sensor that tells it to send fuel. It runs when sprayed with starting fluid
Well just cause it has fuel doeant mean its the right pressure so you should make sure the pressure is what it should be at the testing port with a fuel gauge
Checked pressure. It's got good pressure it drove fine went to store started it up to leave then it just died and wouldn't crank back have great pressure all the way up into top of intake/ spider injectors.
Wasn't sure if it has a sensor that tells it when to send the fuel through injectors or if it is just the box on top of the injector lines
Most of the time the biggest issue with bad injectors is hard starts. You said yours started then shut off.. So best is to find out if yiur missing spark or fuel. Then go from there..
Definitely fuel. I did replace distributor and button and it will fire right up if I spray starter fluid at air filter
today i tried to change my injectors. it was hard to install with hard plastics line. I finally put everything back together, and now my truck is running extremely rough, and misfiring.
Sounds like something went wrong..
@@backwoodzcustomz1549 update. spider was bad. i brought it back, and got a new one. I put the new one on, changed the spark plugs, and boom truck running better than when it was new. Drove it for a few days, went outside one morning, and now it doesnt want to start at all.
Replaced mine, now a constant cylinder one misfire upon start and a po200 cnf & pnd code. Any ideas where to start
Sell it... Lol no not really... Oh the injector unit..
@@backwoodzcustomz1549 I’m almost to that point…replaced it again last night just in case the part was a defective one. It was, misfire went away. Also wanted to check the plug on the misfired cylinder and ended up ripping the plug. So 2 spider units, new plugs, wires, and a throttle body pressure sensor and boom! Just like that, the original problem still isn’t fixed
@@bigred2oo766 I'd like to act surprised but it's just a really horrible design...
@@backwoodzcustomz1549 agreed. It’s a shame I love that truck so much. Running up on 250k miles and the only issue is occasionally turns over for a min or 2 before it starts
Great video thank you.
Glad we cpuld help..
How long did this take?
No sure we did alot of other work at the same time.
If your good..3-4 hours..if not 5-6..but it’s just r n r ..keep track of what comes off so reinstall goes easy for you..clean the throttle body good and the mass air flow 😎
THANK YOU SO FUKING MUCH !!!
Did you just pull the injectors out? I don’t want to break mine
Just pinch them together and pull them out..
@@backwoodzcustomz1549 mine are a little different
Would this cause it to miss while driving when foot to the floor
It can cause alot of things.. also alot of things can cause your problem...
BACKWOODZ CUSTOMZ 15 how about random misfire code p0300. It seems to idle fine but under soft easy acceleration it backfires and misses and after you get to running speed 55-60 and hold it steady it backfires and misses but if you accelerate hard and fast it revs up no misses or anything also when going 55ish and stomp down it just takes off and goes no problem.
Can this cause your truck to die while driving and stopping
Yes..
Where does the injector connecter white wire plug into
i'm not sure what you mean.
Whats the part number for the new injector assembly?
There are tons..
Dude!!!
Thanks man...
Glad to help
The plenum is giving me trouble Any ideas on how to put it on
Read the injector install info really carefully there are 2 injector wire you have to route unconventionally or the plenum will never go back on. I know you prob already figured it out but posting for others trying to service it in the present. 😊
@adrian garcia just keep at it.
Would a bad spider injector throw oxygen sensor codes? Rough idle and eating fuel.
Thats all the issues...
BACKWOODZ CUSTOMZ 15 yes, I replaced oxygen sensors.
BACKWOODZ CUSTOMZ 15 plus had a cylinder 3 miss fire. But that code cleared. Never came back.
Would this cause fuel to leak out down the back of engine and on to the exhaust or is that a seperate thing by itself??
if your leaking fuel out the back of an engine, i would look at the fittings where the return and feed connect to this, or something got rusty, but i think the lines are stainless..
What is the red cap on top of spider injector?
I think your looking at the seal gasket?
What type of spider is it?
Factory.
My truck won’t start up it will just spin over could I be the spider injector
Could be anything.. Spider normally causes a hard start... Check to see if you have spark and fuel pressure
What about the one / three crossover?
I'm not sure what you mean?
The driver side injection hose routing. The picture in the instructions is very poor.
What’s the price range for a repair like that?
If your going to do it yourself like $200
Cool, thanks!
Hola qué ventajas tienen esos nuevos inyectores contra los anteriores?
Duran mas y se pueden reemplazar individualmente si uno se daña aparté de que son mas baratos que comprar toda la araña.
@@HIDHIFDB @ osea la original tiene los inyectores arriva ? Y esta otra los tiene dn la punta de linea?? Correcto?
@@gerardolopez5875 si, la pieza original tiene todos los inyectores unificados en una piesa que envia la gasolina por la manguera, mientras que el reemplazo tiene los inyectores en la punta y se pueden reemplazar.
@@HIDHIFDB @ gracias!!! Mi motor se lleno de gasolina!!! Al desarmar visualmente el regulador roto,, pero crrees k esta tambien es clave? Osea k tambien aga mismo sintoma?
@@gerardolopez5875 ed recomendable cambiar los 2 de hecho creo que el pulpo de repuesto ya viene con un regulador incluido, yo se lo puse a mi blazer motor vortec 4.3 y anda igual que con la pieza original, no perdio potencia ni aumento su consumo de gasolina.
Hello, if someone can tell me if the thin tube of the fuel pressure regulator should have a hose
No. It looks like it should have one but it is in case the regulator pressure gets to high. If it does, then the fuel is dumped out of the regulator.
The vaccum line?
I did mines n didn’t turn on just would back fired but before I change them engine was running now it just turn over n make a pop sound
Gotta be something you touched so start there.
Were u able fix ? Is it making a clank sound half split second?
I heard you say that if you break the old clips that the whole thing is trashed. This is actually not true. You can buy the clips and orings from carparts dot com
Lines..
Where are you guys located at?

My husband is having me TRY to find out HOW TO REMOVE THE SPIDER INJECTOR - PERIOD. Everyone I checked already has the spider out, but he can not put a new one in, till he finds out HOW to take the old one out. :(
Well this video should be what you need.
BACKWOODZ CUSTOMZ 15 unfortunately not, you could’ve popped one of the new poppets you installed out to show us the removal of the newer version thanks
find a new husband
@@gayrunnycumstain this guy!! Haha
I have in the injectors in but can’t put the plenum on top
probably dont have the injector block seated properly
do you know the part number of your new part an where did you get it
The customer brought it. Just go with the cheapest 1 you can find...
@@backwoodzcustomz1549 Nice vid guys. I heard from a very experienced GM guy that you should only use AC Delco and not to go to AZone or Oreillys or get aftermarket, but get it from Advance Auto as they have a supplier that orders Ac Delco direct. Cost dif is about 200.00. Appreciate any info.
Yeah, it's nice they got rid of poppet set up. Those vales are notorious for failing. My 99 Yukon has 203K on it and after a tune up it's still misfiring with no codes. Thanks for any help!
@@freedomkeeper8003 i mean, ac delco is no longer an oem supplier for gm... They seperated many years back. You need to figure out if its an ignition or fuel missfire.. Also could have coolant leaking in the cylinder... I use nothing but the cheapest china parts i can find.. I have lityle to no issues... There is only like 5 manufactures of autoparts.. Most are just relabled boxes...
UPDATE: Problem solved! I opened the hood in the dark, saw arcing plug wires in three places. Replaced wires and no more misfire. Got wires from Summit Racing. Used 8mm, sprial wound core and 270 ohm. Great price too.
They started using those new injectors on the 03.
Yes, they are the upgraded style..
🙂👍
Glad to help
Replaced mine on my 97 now its running on 3 cylinders
Something we wrong
Now it jumped time yesterday luckily I found another motor cheap
Sell it..
Nope It looks way nicer than the one in the video
I got the motor for 100$
I just did this n I think it hydro locked
That would be a new one..
Forgot to do a pressure test on the new spider to see if it hold pressure
Will be pretty obvious after you run it..

DO NOT USE VASELINE!!!
I'm no mechanic, I can work on my own shit, but I wouldn't call myself a mechanic, however, what I am is a maintenance technician. And after eons of experience, I can assure you, vaseline sounds like a good idea, however, it will eventually break down rubber.. so. I'd suggest plumbers grease. Danco brand is the best. Comes in a small squeeze tube.. I use that shit for everything!!! Just saying.. carry on!!
Never had an issue... Also it's what they teach mechanics at school...
this job isn't for the amateur. there were a lot of steps, pain and not nice stuff editited put of this. if your mechanical inclination is average get help or do not attempt
Lol.. it's not that hard of a process and all my videos show all steps needed... I've been in this business for nearly 20 years.. this isn't expert mode...
Fuel rail removal was my problem skipped right over it
There is no fuel rail?
Doesn’t seem to go past the o ring seal
It's tricky..
Sounds like it still had a misfire.
Chevy things....
You didnt tell anyone tjat they are numbered
