#225 of 231 Re: 97 GMC Jimmy issues [jonnyring] by homefixit Sep 01, 2009 (7:21 am)
Replying to: jonnyring (Aug 26, 2009 1:29 pm) Thanks for the help. I did end up dropping the tank to replace his very hard to find o-ring gasket around the pump. The person that had installed his pump did so with a hammer he said, I put a little grease around the top of the tank edge as there was a little rust and was able to get in by hand with a little effort. (NO HAMMER) That is why his gasket was cut like sliced and he couldn't fill the tank. He can now fill the tank without worry as to spilling fuel on the ground. The gasket was around $9+tax. Then we found a shop that advised us that what you said is correct there is a fuel pump relay that is mounted in the glove box in this year truck. It seems that when this relay goes bad and gets hot it tells the pump not too run as it thinks the pump is too hot to run. Actually there are three there in which we replaced the right two at $10+tax each and he is now running perfectly without startup issues. The book he bought barley speaks of it unless you really dig into the paragraphs and there is one picture and you wouldn't know it is in the glove box unless you really look for it as it is covered with a plastic cover. I hope this can help others.

Replying to: homefixit (Sep 03, 2009 1:38 pm) "Where do you find this temp sensor? "   On a '97? I don't know. There are 2 water temp. sensors. 1)On my '91 V6 4.3L (throttle-body injection), the gauge sender/sensor was on the pass. side of the engine right below the forward 2 spark plugs. 2)The ECU/Brain sensor (the one you may wanna replace) was located front and center on top of the engine next to the goose neck (where the upper radiator hose enters the engine). Now I just looked on my wife's 2000 (4.3L with fuel injectors, not T-body injection)...and it could be right next to the goose neck as well, however, if it is, it is HUGE.....much larger than the older 4.3L.

Replying to: jonnyring (Sep 04, 2009 4:08 am) Thanks for the info he looked at it and said it is the size of a small soda can. It is a big possibility that this is it and he will be checking it soon. The truck overheated once he said but not since then as he had that fixed by someone. Thanks again i will update when we get it figured out.
#230 of 231 2000 GMC Jimmy stalls and now wont start by nebulis Sep 15, 2009 (11:40 am)
I was driving home yesterday and stopped at a red light. My Jimmy stalled and I had to restart it. When I restarted it there was no power when i hit the gas and it stalled and died again. Now it wont start at all. Anyone know what could possibly be wrong?

I was driving my jimmy down the road and when i hit the gas to speed up it cut out, its like when you run out of gas and it just shuts off. When i left off it was like normal, but then when i pushed the gas it cut off again. I pulled over put in park reved it up a little bit and sounded fine, i put it in drive and it died. I re started it and started up, i put it in drive then it shut off again. I put another 6 gallons of gas in so it has enough gas. My check engine light came on about 2 weeks ago but it went off the next day and hasant reappered. Now My gas gage has been messed up for a while. Now does anyone know how to fix this? I thought maybe a new fuel pump? or spark plugs? something. Someone please help its my only vehicle and i need to get it running again please?
