97 Grand Prix GTP starts up then dies. How to check fuel pump resistor
HTML-код
- Опубликовано: 14 авг 2024
- I show in this video how to check the fuel pump resistor. I do this by removing the fuel pump "relay" (believe I say fuses) and bend the 1 terminal out of the way. This puts the fuel pump in high and if this works then your fuel pump resistor is the problem. Thanks 4 watching. I hope this will help someone out there.
Thank you! This temp fix got my daughters car to the shop for repairs and saved us a towing bill.. thank you! Wayne
Wayne Anderson your welcome glad it could be some help!
What was the actual issue
Worked perfectly and no tools required. I wish I knew this before I called for a tow . Thanks .
Better late then never as they say,lol
@@2001pontiacta Very cool , my name is Kerry , I've got a Bright Red 98 GTP with only 90,700 miles ( 146,000 kms ) So now do I need to track down the resistor and replace it , bend the relay tang straight and re install it ?
lol this actually made my car run new to the 3800 series and all her problems. can confirm this is fuel related even though you probably fixed it
After I changed my resistor which was located inside the passenger front wheel well, I ended up charging the fuel pump to, n then that issue was not longer a problem. Thanks to Pontiac under your rear carpet, they have a removable access panel, which the fuel pump is located right under. I figured it was fuel or spark issue. You could also check your fuel press on the fuel lines. I can’t remember what the supercharged 3800 fuel pressure should be off the top of my read.. hope this helps
@@2001pontiacta i appreciate the information my brother. do you know if the fuse fix was a long time temporary fix or short?
@@WhosJay your absolutely welcome my friend. Personally, I would think that relay trick is a short term thing. I don’t know if it would burn out your fuel pump prematurely since your putting the fuel pump in high speed all the time….so, I would do this just to kinda isolate where the problem is… hope this helps, n good luck!
Thanks for the video! Direct and to the point, helpful. If anyone is watching this nowadays Am curious, if when you all say "resistor", you actually mean relay. I remember resistors being used in a circuit to introduce resistance. I have looked for said resistor on the car and on line and no luck. Thanks again!
Roberto Santiago Rodriguez happy to hear this was helpful for you! Yes, I did mean relay,lol. Mine my located inside the passenger side inner fender, behind the plastic wheel well cover. Had to remove the wheel to get in there to remove the wheel well plastic cover. Your welcome again!👍🏻
Have a 97 , will start somtimes then day later or same day wont. Start back up. Put a code reader on it only thing it said cylinder 3 misfire switch the plugs and wires out. I could hear the fuel pump turn on didn't know if this might be the same issue you were having at first going to try this though. Thanks for the video
Off hand I don’t remember, I know longer have the car. Did you also change out the coil pack? It sounds like to me a spark issue with possibly a fuel issue to. Start with the cheapest parts first....that’s what I do.. hope this was helpful
Thanks so much for this, got me to work
Absolutely! Glad I could help you out!
Thanks Kerry,
Had the same problem as all the others... I bent the module prong and she started right up, ordered a resistor, should be running by the weekend!
Thanks again!
D. James glad I could help!
After changing my fuel pump resistor I still had the same issue so, I ended up changing fuel filter and fuel pump. Luckily on these car you don't have to drop the tank, there is a door in the trunk once you remove the carpet you can get to the fuel pump. good thinking on Pontiacs' part there.
2001pontiacta what do u think of this mine is same car but 98 it does the same thing as ur car but after i start it back up 2 times it stays running fine only dose that on first start up did urs do that an what do you think it is
trenton moos my Grand Prix GTP would not start at all even if I tried starting it repeatedly. Not sure what your problem could be exactly but, could be that when you start the car repeatedly or turn the key on repeatedly it primes/pressurized the fuel in the line which is why it starts.....so, with that being said could be a fuel pressure issue. Did you try putting a fuel pressure gauge on your fuel line and seeing what kind of pressure you have? If so, does the pressure hold, or does it drop? Hope this helps you out.
2001pontiacta no haven't try that yet i just got the car so haven't dont much to it all try that an let you know what happens maybe you can give me some tips or tricks on what to do next
Ok, I will definitely tell you what I think to do which might help. Hopefully I can help you get this problem fixed man.
Where is the resistor located?
Worked for me! The video is appreciated!
John Atkinson Your welcome and Glad it was helpful for you!
A better way to test would be to swap it with a relay just above it. That way if it is good, you don't risk breaking off the leg of the relay.
This is a relay for anyone who may be confused.
BassManBobBassCovers.....if they read the description I do correct myself. Thanks
Good vid! @@2001pontiacta
Hey! I have a 2003 GTP Grand Prix and I've been having the same issue. It fires but then putters out and quits. I changed the filter and same thing happens. I'm going to give this a try when I can, and if this isn't it, could possibly be the pump? I have pressure to the engine in the fuel line, but maybe my pump is wearing out?
Sterling Glover when you checked fuel pressure to the engine make sure while your checking the fuel pressure and the engine is running that it is holding a good steady pressure. Make sure when you changed the filter( guessing you mean fuel filter) you have it installed the right way. Should have an arrow showing the flow direction(I’m pretty sure the lines are different in size so you can’t hook it up backwards)? Make sure your lines are tight, could be sucking air. Hope this was helpful.
This brought back some memories.
Back in ~2005, the best I could find on short notice was details on how to hot-wire the relay to achieve the same effect. By then, my lovely '97 GTP had over 230K hard-driven miles on it.
That was the _second_ time the fuel pump resistor had failed on that car. The first time it failed, my mechanic replaced it, and had several choice, erm, _descriptive adjectives_ to describe the process.
You know it's a bad design when there were shops selling resistor-relocation kits to move it out from the chasm behind the battery to someplace more serviceable. You've got the dogbone, the washer fluid reservoir, the battery, and I forget whatever else in the way to get to it.
IIRC, around 2000 or so they moved to a solid-state controller that managed the fuel pump more actively. I forget now-it's been too long. I'm sure someone more knowledgeable can pipe up with details.
That car was a hella fun car. The engine was built in my home town (Flint, MI). I drove her hard and loved every minute of it. Except, of course, when stuff like this popped up.
Joe Zbiciak yes I always wanted one of these cars when I was younger, sporty and supercharged!! I always like how they look so wide too! I bought this one with a blown motor and 198,xxx on the odometer. After dropping about 3K into the car with motor, gaskets, fuel pumps and sway bar, sway bar bushing, the list goes on and on. I had enough when I had lost low bean head lights, tried many things to fix it with no solution. So a sold it for 500$ bucks! Hates to lose all that time and money but sometimes you gotta know when to throw In the throw. She was just a beater as she was rough, nor body wise (rusted) just cosmetically.
Thanx for sharing your GP story.
That's a relay not a fuse , and a fuel pump resistor if its located on the inner fender or fire wall , can be tested with a meter on ohms without having to damage the relay by bending the leg !
JOGO in my description I do correct myself and say that I called it a fuse when it is indeed a relay. Yes you could test the resistor to find the defective part. For people who don’t have a meter to check, this is a cheap easy way....
Holy shit actually works
Thanks for posting the video because it got my car back up and running. I got a 97 GTP. So the problem was the fuel pump and not the fuel pump resistor?
No problem, glad to hear it helped you. I know I watched videos that helped me so, figured I'd post mine to help someone. Thank Pontiac for having that little door/pocket to get to the fuel pump without dropping the tank!
N yes it ended up being my fuel pump. I did change the fuel pump resistor first(started with the cheapest parts first) n it wouldn't start so changed the fuel pump. I also changed the fuel filter too.
This completely just fixed mine. Is it safe to drive it like that with prong bent until new pump arrives?
Glad it was helpful👍, I think as a short term it should be okay. From my understanding it puts the fuel pump into high speed, so not sure if that’s gonna put a strain on the fuel pump because, the fuel pump does normally go into high speed when working properly…
@@2001pontiacta that's definitely a wild temp fix, I tried so hard to track down why it wouldn't start! Already suspected fuel pump due to gas gauge not working/needing sender unit for the pump. Car was on side of roadway miles from home in threat of being towed, '00 Grand Prix GTP, took a few long walks to & from to check on it & seek the issue, was blown away when I bent that prong and it finally stayed running/ didn't shut off. Going to order a new relay & fuel pump in a few days when I get the $ 💪
@@2001pontiacta hey brother, today I put a new fuel pump in, drove to get gas, forgot I had new relay to put in, installed it at gas station, car did same thing, would start and shut off after a second.
Put the old relay with bent prong back in, she started and stayed running, so odd!
The relay issue only started a few weeks ago around when I first messaged on here.
When I got the car a year ago, the gas gauge & digital readout would both stay around full tank but when needed gas the low light would come on & guage drop to empty, telling me to get fuel even tho gauge wasnt working. Low light was helpful. After installing new pump today the gauge is stuck on empty with low light on, got more than enough gas in it.
Tomorrow I'm going to take the new pump out and inspect the arm and float, if I can't find the issue going to put the old pump back in and see if gauges atleadt do what they we're doing, giving me somekind of readout & not stay stuck on empty.
Before I took the old pump out, gauge stayed stuck on full but dropped to e when It was low how it should as far as low gas reading & light, put the new pump in and it's just stuck on empty now with light on.
Crazy shit. I don't think it's related to the relay issue, that started not long ago at all, gas gauge been funky since I got car a year ago, and got worse upon changing the brand new pump today
The problem is the resistor is bad. The resistor if my memory serves me correctly it's mounted inside the passenger side fender in front of the tire. Since the supercharged engines use a 2 speed fuel pump i.e. high speed for start-up and high throttle. I got a fuel pump resistor kit from a GM dealer which was I think like $80. And they require you mount it on the firewall also gives directions on how to locate the original resistor wires. When this happened to me I was beating my head against the wall because there was no RUclips videos on it back in 2008. Dealership really didn't even knew it existed but then found the part no.
@@iron1man7818 thanks! Definitely looking into this
So with the tab bent on the relay, that means the resistor is good? What if the tab is bent and the same problem occurs?
From my understandings, yes. That points the problem towards the resistor. Bending that prong puts your fuel pump in high speed. With that being said, I would definitely start by changing the resistor. It’s gonna be much cheaper then starting with say changing the fuel pump. Believe o purchase my resistor off Amazon or eBay and think it was under 50$ bucks. Hope this helps. Your resistor on the Grand Prix (at least on mine which was a 97) are located on the frame behind the passenger side inner fender well. Not a hard job, good luck!
Hey Great video! Worked for me awesome! Was wondering though how long will my car run like this for? Will I have to replace fuel pump or filter. What do u suggest? Or will I never have a problem again?
I’m not really sure how long this will fix the issue.... I guess for a while if I had to guess, since it’s just putting your fuel pump in high... I would recommend replacing the fuel pump, and or resistor so it’s repaired properly. Last thing you’d wanna do is be left somewhere on a road/highway with a tow bill on top of this bill....I always start with the cheaper repairs first, try your fuel filter, then go from there. I again would recommend replacing all the fuel related parts. Thanks for the comment n hope this is helpful.👍
Can u run the car on that or need to change fuel pump
Nice tip .tks
Jared THISDELLE no problem, glad to hear it was helpful..
thanks man
I have the same problem, but my problem is on a 99 firebird that I swap a 3800 supercharged engine in to it, it was running great for over year but now it has the same issue
I was always told when trying to fix/diagnosis a problem, always start with the cheaper parts first… I’d start with checking your fuel pressure at the fuel rail…. Maybe you have a bad injector? Or fuel pump…
It’s work I just did it
Jamarcus Edwards glad I could help someone out!
Can u keep the car running on that fuse
that im not sure of
Hey , after you bent the contact # 85 on the fuel pump relay did you replace the relay with another one and did it Stall out after ?
I did try another relay with the same results. I even changed out the fuel pump resistor located on the frame/body of car on the passenger side. Thought I'd start with the cheapest part first(fuel pump resistor). Ended up changing the fuel pump in the end anyways.
Where on the Passenger side FRAME /Body did you find the Resistor ?
dna090861 I had to remove the passenger side wheel, and inner fender well. It was located in front of the front wheel on the outside. If you remove the parts I listed above you should see it with ease. I just sold this car so, sry I can't send you any pics. Hope this helps you out.
dna090861 when I say "outside" I mean on the outta part of the fame/body. It will be facing you.
dna090861 I did try other relays with it still not wanting to start.
Hi! I have been having the same issue's with no check engine light ect and have 2002 grand prix gtp but I'm looking at mine and am only seeing the on the right next to it. I'm missing the one you had gotten out. I was told to pull my horn and switch it with it but am having trouble finding it. Can you post a pic of the horn relay by chance? I see it shows #16 but am unable to figure it out.
rachel crowe hello, unfortunately I no longer have that car due to I lost headlight(low beam) and couldn’t figure it out to save my life. So I decided it was best to part ways with the car.
@@2001pontiacta I'm sorry to hear that and thank you for getting back to me so quickly
I can bypass resistor and car will run ok, I put 2 new resistors on it and it still does after 2 seconds, it has to be a bad fuel pump right
Clint Jones have you hooked up a fuel pressure gauge to monitor the fuel pressure? Just to confirm it’s a fuel issue. It could possibly be a fuel pump. I would start with the cheaper parts first, have you changed your fuel filter? If not, I would start there, they are cheaper then a fuel pump. If you need a fuel pump try online(eBay). Better price on there, might not be name brand. Not
Sure you model of car but, if a Pontiac Grand Prix GTP(supercharged) make sure to get the correct fuel pump. I believe the GTP fuel pressure is a bit higher then the regular 3.8 liter non-turbo. Hope this helps you out.
Hi..I have a 98 grand prix.my problem is not in the gas pump and nothing about that..my problem is about fuse box in the front..the problem is ..when I start the car for do a ride in the nigth..the head lamps don't work..I don't have lights..but..if a grab the cables on the fuse box and moving ..the lights works good..but when I go to drive an hit some hole ..the lights go off...I hope some one can tell me what to do about t
Marco Ocasio to be honest, I have no clue. I ended up selling mine because I all of s sudden lost my headlight but, I had parking lights. I changed the main light switch, I chanced the wiring in the steering column(the turn signal, dimmer, windshield etc). Sorry I can’t be more helpful. I would say check your ground wires, make sure that are grounded good, or check for a short....good luck
How can I fix that problem with my car 1998 Grand Prix
Jamarcus Edwards if your having the same issue, new fuel pump, or new relay or new coil packs
This is a big problem in our country
Cars Stalling
Big problem in dodge magnum 2.7
Its Ridiculous
I have a 07 and my car has done this for months. We have put in a new fuel pump, ignition control mod, spark plugs and wires, new battery, you name it and my car still won't run. Could it be the cara brain? I'm running out of things to think it is.
Haley Vannaman are you sure it’s a fuel issue? Have you or can you start the car and check/monitor the fuel pressure? Have you checked relays? What about the fuel pump resistor? Not sure but, mine was located inside the passenger side wheel well, behind the inner fender. When was the fuel filter changed lasted? Is the vehicle throwing any codes? When the cars about to shutoff do you have any response with the throttle pedal? Could it be throttle position sensor?
@@2001pontiacta honestly I'm not sure of it is a fuel problem. We have check relays and they all seemed fine but something was making them jump. I can't remember which one it was. My car did throw a code about the computer. (Not sure what the code was I just know my boyfriend looked it up and said that's what it was) when its about to shut off i can push on the gas and it have no response. We replaced the pedal sensor also. Just seen your videos and thought id ask. My car has been sitting in my drive way for 8 months because it won't go more than a few inches without dying.
Haley Vannaman okay....sorry I can’t be more helpful. I will keep thinking to see if anything else comes to mind. Do you have power (to lights interior light, exterior lights)when the car dies?
@@2001pontiacta yes. I have light, radio, power windows. The code was P0601 saying my ECM is bad.
Do you know if the crank shaft position sensor has been changed?
try replacing the fuel pump resistor
That's the only one I cant find for a 2001 Pontiac grand prix gtp, where is is at?
Mine was located behind the passenger side inner fender well
how long can I go with that bypass like..
John Reed to be totally honest with you, I don’t know. I would say this is a temporary fix/solution. This, to me is a more diagnose to find your problem or point you in a direction to fix the problem. I, myself wouldn’t make this a long term fix. I would think that making this a long term fix, is like putting a bandaid on it which might cause other problems but, again I’m not sure. Hope I was somewhat helpful..
Until the fuel pump dies
I can drive my car all day but once the motor get hit n true it off it won’t start nomore until it cool down
Jamarcus Edwards is it overheating? I would check, coolant, thermostat. Make sure the coolant is flowing, run the car, when it’s cool open the radiator up(take the cap off make sure it’s circulating).
Just put on the mass air flow
Jamarcus Edwards it’s still stalling out? Do you have a gauge to hook onto the fuel line to see if your losing fuel pressure?
Maybe a bad fuel pressure regulator
my car does this i have fuel in the line it cranks then dies
J Rob Did you check the pressure in your fuel line while the car is cranking? Your line might get pressure but, then lose pressure after you crank the car. If you have done this, I’d say you definitely have a fuel/fuel pressure issue. Might be your fuel pump? By what your telling me if sound like the car is being starved for fuel. Again I would try to monitor the fuel pressure while trying to start the car. I don’t remember off hand what the GTP fuel pressure is supposed to be. Hope this helps
Fuel pump not turning on
Ryan Scherbluk check fuses or relays
Where is the fuel pump resistor?
on my 1997 Grand Prix GTP it was located on the frame/body on the passengerside. Inside the wheel well. You will have to remove your tire, inner wheel well. If my memory is correct its only 1 bolt/screw that its attached with. If you need to replace it, don't go to the dealer or parts store. Much cheaper online, think i paid like 25-35 bucks. Its not a hard fix or job. hope this helps.
@@2001pontiacta is that where is at on a 2001 grand prix gtp?
He replace my fuel pump but the car want get gas when I put it in drive to go
Yes, like stated a few comments above try your fuel pump resistor(located on the passenger side front frame part if you wanna call it that. not a hard fix just have to take off tire, inner fender well. or try the relays. Start with the cheapest parts first. the fuel pump resistor is cheaper online(ebay,amazon etc.) hope this helps you out.If none of these work, make sure the fuel cable is connected, sometime its dumb thing like that too.
