Hi everyone. My 02 grand am has spark and 55psi at the fuel rail but will just crank and not start. I can get it to start and run on starting fluid but once that burns off it dies. Im going to noid the injectors tonight but already figure there is no pulse. Ive tried the whole security thing and thats not the issue. Ive checked all fuses and relays and they are good. The last time the car ran it ran fine and the next day just would not start. Im lost and would apreciate any advice.
