I own a 1990 Pontiac Sunbird and 2 years ago the car stopped running, it first wouldnt start one day than the next it did than it completly died. I than left the car alone for 2 months. I checked the car over and realized the fuel pump was not on so I repaced the fuel pump than the relay than the oil pressure switch. When these did not work I took the car in to my school. This was a few months ago. Me and my friend than just decided to bring a hot wire to the pump. It now pumps fuel to the throttle body but now wont inject the gas in to the engine. So we tested for power and we got juice coming to the injector but it wouldnt inject so we cut the blue wire and grounded it to the frame. The car now injects gas but it floods it self out. I realy need help, winter is coming up and this is my old dependable car.
So I did a little looking and I realized the computer should turn on the pump and injector. So there is something that should tell the computer to sent a signal to the pump and injector, and thats the problem, SO WHAT CONTROLS THE SWITCH IN THE COMPUTER TO SEND A SIGnal TO THE PUMP AND INJECTOR?
have the same problem?
