I picked up car after having new clutch installed... 20 minutes later car died and wouldn't start... Had car towed back same garage and he claimed Fuel Pump went out, but that he got it going again bt tapping on it... I got the car home and installed a new pump myself (beats the $400 he wanted)... Car ran fine for about a day then stalled again and will not start... I checked to see I had spark... I also checked to make sure pump was working and I have fuel up to injectors... I suspected main relay so I hotwired fuel pump and car still won't fire even with pump running manually... I don't think injectors are firing, but I don't know how to check them... Can anyone help?

Labman would suggest pulling the injectors (with the rail attached) from the intake manifold, pointing them to something that will not cause the fuel they will squirt out to ignite, and have someone crank the engine. That way you will see if they are delivering fuel. If they are, then perhaps you need to adjust your timing?

Yeah, Crocivic saved you waiting 3 hours for me. That is a little trick out of the factory shop manual for my 92 Grand Am. Too much of the advice in it called for hooking up their Tech I computer.
