i have a 2003 grand am 5spd. i was at the store and the car started running very bad. I started going through everything and here is what i have found. I pulled the fuel rail w/ injectors out and set a piece of cardboard behind them. I turn the key and gas comes out of the 1,3,4 injectors. I checked the #2 injector and swapped it with another i know works, still nothing. I swapped the wires and whatever injector the #2 injector wire goes to doesnt work. I dont have any engine codes that help. I am starting to think this is just a wiring issue. Whatever it is , it has me sidelined. Any help would be appreciated. thank you.




Also, im pretty sure it will, but will a 2003 ecotec from 5spd grand am , drop into a 2002 alero or 2002 l200 saturn auto?

Did you get you injector problem resolved yet?
