Engine Mechanical problem
1988 Pontiac Firebird V8 Two Wheel Drive Manual 150000 miles
HI, I have an 88 firebird formula with a 305 TPI engine. The car will start up but it will die almost immediately. It will run really rough tho if I sit in there and pulsate the gas pedal really fast, but it dies a couple seconds after I stop. It also backfires a lot out of the intake.
In trying to solve this problem I have:
replaced the spark plugs, plug wires, vacuum lines, fuel pump, distributor cap, rotor, and fuel filter.
also, I tested to see if the car ran when I hooked up an ecm off of another 305 firebird and that made no difference.
and I replaced another thing that said "ac spark plug" on it, it was located under the passenger side panel.
also, I have unhooked the fuel line at the fuel filter and it is getting plenty of fuel there, and I also tried to jump the fuel pump relay and make the fuel pump run constantly, but that did not help either.
none of these things has helpled it run better. Please help me.
have the same problem?
