Hello All,
I got an all stock 98 Tahoe 5.7L. To start, a few months ago the thing just died on me during a short trip. It turns over but wouldn't start. I have since replaced multiple ignition components (alternator tested fine, distributor cap, ICM, etc...). I ran the complete troubleshooting procedure for the ignition system and all signals checked out perfect. The fuel pump was about 2 years old, less than 10k miles (just use it as my get dirty work horse). Since it has been dead and sitting, the fuel filter was replaced as well. It sat there most of winter, while I would go poke around at it here and there on nicer days. Still cranking but no signs of starting.
Finally I got ahold of a local shop to get it towed to because I gave up and it sitting there is starting to get in the way. I called AAA to come get it and the driver was chatting with me about the problem. He walked right over to the fuel tank, banged on it a few times, and it fired right up!!!! He said I ought to get the pump replaced. OK well I kept the Tahoe to do the pump replacement myself. I let the Tahoe run for about a half hour while I did yard work. I shut it off and it started right back up. A few hours later my wife and I were going to take it for a spin. Wouldn't start again! Tried the banging trick and nothing. Turns over and cranks but hear no signs of wanting to start. I order my new pump and just got it all back together today. Fired up after a few cranks but quickly died. It went back to the cranking with no signs of start. After about 5 minutes it started up and would only stay running with me giving it gas. This lasted for about a minute and it died again. Now it is back to the cranking with no signs of trying to start. I am stumped at this point.
I thought it was solved!!!! Also previous to the engine dying off a few months ago, I has ZERO signs of anything going bad, just up and stopped working out of no where. Fired right up every time and ran like a beauty.
