96 S10 was running fine; shut it off for 15 minutes; now it will only turn over....any suggestions?

Need to see if there is no fire or fuel. Take the air filter top off and spray some starting fluid in it and see if it starts. This will tell you there is no fuel if it does.

It would hit when I sprayed starting fluid in it, but it would continue to run.

So it does start with starting fluid?

Sounds like your fuel pump is failing.

Take a hammer and smack in the center of the gas tank and see if it will start.

Is that a vortec engine? If so do not use starting fluid in it. If it backfires thru the intake You will blow the plastic intake to pieces. I still find parts of my intake sometimes in my back yard.

Yes, it does start with starting fluid. Thankfully, it didn't backfire! Will try smacking the gas tank tomorrow. Thanks for the help.

Can also check fuel pressure at intake.

If it starts you need a fuel pump
