Starting Issue on 97 Suburban

[scalescratcher]

Own a 97 Chevy Suburban w/ 5.7 L V8. 3 weeks ago went out to start it and it wouldn't go. Initially turned over sluggish but turned over easily after a few tries but still wouldn't start. Had it towed in. The shop tired to start it and found no issues. Kept it for 3 days and it started each day. Checked fuel pressure, spark and usual other suspect areas and found nothing. No codes found. Truck has run fine for last 3 weeks although used sparingly. This morning am having same start up issue. Truck has sat for 4 days unused but showed no issue in last use. Any thoughts????

Maybe fuel pump getting weak. Try replacing fuel filter if you can break the fuel line,they are usually rusted big time.

You didn't say how many miles. I replaced my fuel pump at 150k give or take. Was common issue I guess.

Listen for the Bzzzz of the fuel pump when you turn the key on. If you don't here the Bzzzz and it still wont start sometimes hitting the fuel tank with a rubber mallet will get the fuel pump to kick on and start.

Thanks for the replies guys. Sorry for the delayed response. Truck has 240k and the fuel pump was replaced at 125k. First time in the shop could not find issue after 3 days. Second time found an intermittent short in the distributor. New cap and rotor and I'm back on the road (knock on wood). The symptoms were isolated around the times of warm weather with colder temps moving in. Not sure if this had anything to do with the issue but the fix seemed to take care of the problem. Going on 3 weeks with no further problems and the truck seems to be running better to boot.

Thanks again
