i cant figure it out, my car was dyeing ocasionally and then it became more frequent now it wont start at all just sputter for a second like a fuel delivery issue, i was told it was probably low fuel pressure so now i have a new pump and fuel filter and i have good fuel pressure (didnt fix it) i checked spark on all 8 and it checked out, i had a mechanic check it out who usaly does german cars and he sprayed starting fluid in the tb and it still just sputered but for twice as long. he said it didnt sound like the injectors where fireing when he put his stethascope to it this is my first fuel injected car and i have no clue whats going on.

 

It may very well be that the injectors are shorting out. GM started to use Multec injectors in '88 or '89, called recall which year. If they are Multec's best bet is to just replace them with a decent set of Bosch injectors.

The Multec's have been doing the 'short out' thing for years now. And is becoming a major problem for folks that haven't changed them yet.

Check the resistance of each injector. Any that are under 12 ohms are bad. And one or two at 2 ohms is enough to prevent the ECM from firing any of them.

thank you very much ill check that out today i origanally thought injectors but everyone said they dont all just go out at once.

 

if it is recaled injectors would it still be posible for me to get free ones from gm (long shot but im on a budget)
