California designed grounds ,not so good in Ontario salt country, thanks for taking the time to show us Phillip/
I teach automotive technology. We are working on a 2005 GMC Envoy with this problem of no control circuit to the fuel pump relay. This video has been a great resource for continuing our troubleshooting journey. Thank you kindly. P.S. I wasn't bored... :)
I'm glad it helped you. I teach Automotive Apprenticeship in Confederation College in Ontario Canada. Where are you located?

@@PhillipBailey Oak Ridge, Tennessee. I am from Watertown NY though, just south of you. We probably grew up watching the same TV stations...
Great Info, At least I have a starting point to look at. Thank You
Me to
good diagnostic thanks
I hadthis problem I just tightened the bolts on the fuse box started right
Almost always a ground problem!
Great find. When it won't act up it's tough. I think that I would of tried to get at all the wires that go to the ground bolts on the upper top side, may have been easier. Slice into them and get a good clean upper ground point. Thanks, I have a 2005 TB in Goderich Ontario, home of the world's largest salt mine!
it seems like this video was made by voice actor of Joel from The Last of Us game
Lol never heard that before...
@PhillipBailey meant it as a compliment 😎. Struggling with my TB with same symptoms🥲
Excellent video, Thanks!
Thankyou for watching.
Again you have patience has come out on top thank you for sharing your time and knowledge
Almost have to be a contortionest for those grounds. Lol
Alright, I’ll offer something just to ask
My friend bought a 2007 trailblazer, there’s a handful of issues. But the main thing is the engine starts, it cranks beautifully. But once it gets to idle it doesn’t hold it.
It dips under idle and stalls. My mechanic friends have been suggesting vacuum leaks. If it is, how would I know?
Can you keep it from stalling by stepping on the gas pedal? If you have a vacuum leak it will be running lean and the fuel trims will be significantly positive. You could have a dirty MAF sensor or it could be under reporting the air flow at an idle. Try disconnecting the MAF connector to see how it runs. Check the canister purge valve for leakage. HTH
@@PhillipBailey first of all I really appreciate this help, also yeah, throttle will keep the car running. I will go ahead and give those a shot
Nice High technology. ❤
Hey, bud. I hope you’re well. Mine stalling when idling in park but not in gear w/ brake pedal. Assume vac leak somewhere, not sure where as it’s not jumping out at me.. Any tips?
Scan it for codes first, check for induction leaks, check fuel pressure and watch data parameters before and during the stall. There are lots of possibilities.
How can i know if i got problems with the Alternator..by the way I been switching from Premium gas to regular gas ⛽️
I would not recommend premium fuel it's actually less volatile and can contribute to starting issues cold. Have the alternator diodes tested with a lab scope.
@@PhillipBailey thank you Sir
I have this exact problem, mine will start fine and drive but once warm, when I slow down to a stop it constantly wants to stall
There are multiple causes for that. Start with a scan for codes
A bad coil pack

Are you asking a question?
Boring
Yes my video quality is not up to Spielberg standards and it's not very entertaining for sure...
