There probably isn't a lot of S10 info around here but I'll throw out some generic GM info. If GM was smart enough to put a fuel pressure port on your fuel rail it will be easy to check fuel pressure. If not, then you will have to listen for the pump and look for any fuel squirting in the throttle body (I assume it's FI). If it starts with a little gas or starting fulid then the pump could be bad.

You should be able to check for codes by using a paper clip. You might have to google that. There is probably S10 forums with more info on those things. Good luck.
