I own a 98 Chevy blazer an it won't start sounds like its not getting gas so I ck the fuel pump an it's pump like a champ ck the firing mechanism an it seems to be fine ck all the fuses an they're all good. What else could it possibly be I'm stumped????....

 

fuel pressure check, and a spark test is what you should have done if you've done both these tests what are the results and readings?

 

I've ck the pressure it holds at 50psi seems to b fine idk what a spark test is. I've toke a wire off the firing mechanism an watch for sparks when someone else cranked it an it definitely sparks.

 

50 is too low. Change fuel filter then check it again. if its still below 60,time for a pump. Yes these things are this sensitive on pumps. Only buy a ac delco or delphi pump.
