After replacing a broken fuel injector on my cavalier i cant get it to run. I can hear the fuel pump start when i turn the key to the on position but when i try to start it it sounds really rough and just dies and backfires once in awhile. The injector i replaced initially started spraying gas out of it and i had to adjust the o ring seal but now it doesnt leak when i try starting it. Im not sure if i forgot a step or i did something wrong but any advice would be great. Ive been adviced to "prime the fuel system" and have no idea what that even means...
Use a gage and check proper fuel pressure, 41--47 psi, key on engine off. Cycling the key on and off a few times before you crank it, should prime the system.
Check for fuel injector pulse, use a noid lite, engine cranking. The voltage for fuel injector probably goes hot with the key on. The computer grounds the fuel injector circuit. The diagram is for 2.2L engine. The pink wire for fuel injectors is voltage, the bottom wire is ground. We've talked about the fuel system, could be other issues?

Please call me its easier to explain on the phone, in the mean time try something easy hit the fuel pump on thebottom with a brick or rock then have someone listen to the fill neck of the tank for the two second "buzz" as soon as you turn on the ignition, has this vehicle been run way way low on fuel many times or the fuel filter neglected to been changed at the 15,000 miles interval?

it sounds like the check valve in the fuel pump is letting the fuel bleed back into the tank

The Fuel Pump is Only Supposed To Start For Only A Second.

My 2000 cavalier has done this for 6 months. You take your key out then open your door, wait ten minutes and the system resets itself and the car will start-annoying you bet!!!
