At least you got ripped off by you self and not a corrupt mechanic 😂
Thank you for the post you saved me a lot of time. I changed my brake shoes and afterwards I had the same problem as you. I thought for sure I would be changing a fuel pump. After checking the fuel pressure I started scratching my head. Checked the fuel system fuses and they were all okay which really had me stumped. Checked the same 30 amp fuse that you had changed and it was blown. Changed it and the truck started right up.
Thanks for taking the time to make and post the video it is greatly appreciated.
What does the 30 amp stud-2 fuse control and do? Never saw this before but glad your vehicle and this videos posters vehicle is running
@Average Driveway Mechanic Great informative video and glad to know that we were able to help!
Bro you are the life saver god bless you and your family I have done same thing opened up every wire new every ground cleaned up everything so I’m gonna put back everything and try get a fuse if that’s works and starts the truck you’ll be in my prayers for life thank you
That's AWESOME Thanks for the feed back 🤣🤣
@@averagedrivewaymechanic300 truck is working fine ur the best turns to
Be the ecm ground lost communication thanks again
@Unknown Known awesome! hope i can get your support with you subscribing
@@averagedrivewaymechanic300 abs brother
Mines work too brother !!!! team work right here keep up the good work
Man, Im going through something as head scratching. Im getting u0101, u0073, u0214, co55-5a…
Truck has intermittent no crank. Come to a stop sign and will not engage transmission. Slow throttle response, sometimes No throttle response. Taking shots in the dark. Cleaned all grounds, cleaned all wiring harness, replaced BCM and reprogrammed, checked 16pin connections at trans.. went to two shops.. no luck yet.
Really happy to hear u got your figured out!! Gives me hope for a solution on mine!
The ground behind the wire wall replace it usually if it's a ground issue it's always that one.
It looks like it's a chain link cable
@@averagedrivewaymechanic300 I will try that! Thank you
Thank you for all the info
Nice job you got it running. These new cars are not easy to work on.
Yeah an older model wouldnt be giving me issues at all lol ! Please subscribe
Very nice video thank you!
I have a 2021 Silverado and the brake module is not responding when using the cdsd2 program, should I reprogram it?
did u need to have the computer programmed or did u order a vin specific ecm
Wow 1000 dollars before you found it was a fuse 🤔 you better find out why those fuses blew.
Did you have to flash the ecm
Since I brought it on ebay they flash it before delivery it to me using the vin
unfortunatelly i try this in my avalanche 2009 but it did not work for me, im going to be trying to find what is causing this problem on my truck, thank you.
I have a second video that go into more details
Disconnect the battery and see if the alternator clicks
-if no --->bad ECM
-If yes---> Mechanical or fuse issues perhaps fuel pump or starter
@@averagedrivewaymechanic300 i replaced the ecm crank, sensor, cables sparks on coils good presure on gas, change those fuses and still same problem.
crank but not start.
@@EMITERIO1000did you figure it out? I’m here.
just watched this video my truck was doing the same would just click changed starter battery fuel pump nothing still changed the computer tried to start up started up with starter fluid but shut off when i stopped just put my old computer back on checked the fuses and one of the 40 amp fuse was broken gonna change the computer to the new one i got hoping it turns on
I need your help brother my Tahoe doing the same thang
I’m having the same exact problem with code U0100. So was it the pcm and the fuse or just the fuse?
Check the fuse first .
Then check if you have a check engine light when key is on the "on" position
I have a second video in my channel that's more detail
@@averagedrivewaymechanic300 Thanks I’ve checked every fuse twice, yes engine light is on. This shit is driving me crazy! I just checked my PCM and there is oil on the connectors! I have no idea how that even happens, but I’m going to try to clean them some how and see if that helps.
Good video. What all does that fuse stud-2 control ?
Controls Throttle that communicates with ECM if fuse is good . Maybe you have a bad ECM . See if your check engine light shows when you put the key on run * if it doesn't that means no communication to the ECM
Dammm fool Chevy are a challenge we got a 5.3 silverado and we dealing with this right now lolz
Hi Bro, I have the same problem, code U0100, no click sound, no "check engine" light, if fuses are ok, what else it could be?
Check if your Engine light turns on, in the dash when you put the check in . I have a other video that more specific
Mine dose nothing when I try to turn it on what do you think it could be it’s a Chevy suburban 2000 150
Is their power to the cluster, radio ?
@Average Driveway Mechanic I have this issue and my radio sometimes don't work and sometimes it does. What do u think?
Wow I'm going threw this rite now 😡👍👍👍👍👍
Comment what going on and codes
First the gas paddle stop working ,I turned the engine off .tried to restart it nosignal from the switch it's just cranking from the crank relay codes u0100
@@dangomaure2857 Try Disconnecting the battery first and touch the NEGATIVE & POSITIVE together. To drain any power and then reconnect it. If you hear your throttle body kick open it should start.
And the gas pedel disconnected the connector and re connect it . I had to reset it with the Tech 2
good morning guys hey i have a problem with my chevrolet silverado 2007 6.0 secund generation is been running with problems like you guys experienced in your trucks mine is showing in the dash abs, brake service, stabilitrak check engine, lose power and i allready chage throttle body, gas pedal fuel pump check grounds, fuses. sometimes run for few hours normal and i turned off and don't want start again until desconect battery and plug it back on and run again. so if somebody can help me ill really apreciate that thanks god bless you guys
Bro i have a no crank no start it just clicks i have a new battery and new starter and recently rebuild my engine new oil pump cam and lifters vvt and dod delete it ran fine for like 1000 miles than one day i parked it and when i tried to start it its giving me this issue what do u think it might be?
Does the throttle body click/flaps/spins
When you disconnect the battery negative ?
Clean the negative under the oil filler show at #2.03
Did you have to program the new ecm ? Wat procedure did u use to do it? Just curious
After 2007 from what I understood they need to be Reprogram with the vin. Used or new I Purchased my ECM already Program on Ebay
@@averagedrivewaymechanic300 do you have a link for that?
@@MasterNeko In the Description
Did you ever have the security light on?
No if the Security light is on the key got disprogram
Follow Gm Key relearn procedure
@@averagedrivewaymechanic300 the security light turned on after I took my battery to charge, I tried doing that key thing turn it on leave it on for 10mins or until the security light turns off hadn't had any luck turning it off
This is the exact thing happening to my 5.3 168k Miles. Shop replaced the throttle body, still doing the same rough start but it turns over after I pump the gas
After replacing throttle body you need to program the throttle body again "throttle relearn" maybe that your issue
@@averagedrivewaymechanic300 thank you for your response! I had the same shop reprogram it, it still isn't firing up without me giving it gas. I will have to check that ground cable next, I probably just need a new ecm
My does run unless all of air intake, and vacuum hose are hooked up, if 1 vacuum Line is disconnected is will not run,
Notice when It did start ,the air intake is connected, it's wasn't in the beginning
If anyone having a crank no spark on these trucks check the small ground wire behind p/s pump this wire grounds all coils also multiple misfire and stalling problems
Mine dose nothing when I try to turn it on what you think it could be
I checked those same fuses and still no start. I have the battery light on my dash and have my jumper cables but i get nothing
Does the check engine like show when you have the key in ACCESSORIES
If no might be a sign of bad ECM I have a other video in channel
Check the crank or cam sensors
So we got a 09 chevy silverado 5.3 Ls 1500 right and we switched the engine and stuff when we built back he had no crank no start 🙆♂️🤦♂️🤷♂️ we was like wtf, so we doing research i went to clean all my grounds and added some new grounds, still no crank no start, switched alot of fuses and nothing. New battery and went switched the fuse by the battery and nothing. So my scanner couldn't communicate either and she was sitting there for 4 months with a new engine and new upgrades till I seen someone disconnect the battery and made the positive and negative cable touch each other. To kill everything and then went to disconnect the ECM then after 20 minutes connected everything back and the truck started after 4 months with new engine and new everything 🙆♂️ but I do need a new ECM
LOL! Bet that was Fun 🤣
Bro i have a no crank no start it just clicks i have a new starter and new battery and recenlty rebuild my engine oil pump vvt dod delete ne cam new lifters and it ran for like 1000 miles than i parked it one day and im having this issue what do u think it might be?
Jesus. The barrel musta nearly melted down on your parts cannon ...
Mine will crank fine but won't get fire to the plugs
Does your check engine light glow when you put the key in? Please check my other video to see if its doing the same thing. My wasn't firing until I replaced the ECM

Where did buy pcm from
www.allcomputerresources.com/
Throwing parts on a problem isn’t the way. Proper diagnosis would have saved you lots of money
Hope you can still subscribe to me it's my first time figuring this out
It will crank but won't start
Did you have to reprogram the ecm sheet you replaced it? I'm having the same problem with my 2007 gmc yukon
If you buy the ECM from the link you sent them your vin and it come preprogrammed
@@averagedrivewaymechanic300 what link
ℹ replaced the tcm and the truck will not start or turn over.
I have a code bro u101 lost communication with tcm i did the fuses but no luck
just watched this video my truck was doing the same would just click changed starter battery fuel pump nothing still changed the computer tried to start up started up with starter fluid but shut off when i stopped just put my old computer back on checked the fuses and one of the 40 amp fuse was broken gonna change the computer to the new one i got hoping it turns on
