1999 Chevrolet Tahoe Question: my engine died and would barely run.

 

Question

Visitor, 5.7L V8, Magnolia, AR, June 01, 2010, 19:14

i have a 99 chevrolet 2 door tahoe that i seldom drive. i started it and was leaving my drive when the motor quit running. it would restart but was stumbling very bad at idle. would die as soon as gas was applied if not before applied. i did not get to check anything out for a couple of days. i checked the battery terminals. they seemed to be tight. without trying to start the engine, i checked fuel pressure and had 62psi with key on but not running. i then tried to start the engine and everything seems to be back to normal now. i have test drove it about 5 miles on highway and bumpy roads. the 'service engine light' did NOT come on. any suggessions or should i feel safe to drive it further?

    I would still check the codes and see if any are set. This may have been from sitting, so I would drive it enough to get the old gas out and get some new fuel in there. Vehicles like to be driven, so letting them sit too long can cause weird things like this.

    I drove the Tahoe on 10 mile trip to work and then back home. Everything seems normal. I checked for codes and found the fuse blown that feeds power to the code reader plug. I replaced it but had no codes present. I try to drive the Tahoe at least every two weeks. Usually once a week so the gas should be okay. I guess I'll drive some more and see what happens?
    UPDATE: still going strong on the 'old' gas. It acted like it suddenly either had no fuel pressure or lost ignition? Seems to be fine now. Anyway, thanks for your thoughts. Can you give me some thoughts on the 96 Tahoe 'fuel pressure test' post [June 3rd]???
