I have an 87 turbo rx7 everytime i start it it just shuts right off. If i pull a vacuum line and manually spray fuel into it it will stay running as long as i keep manually adding fuel.... Cant seem to figure out why it doesnt work on its own. Things ive tried already: new fuel pump, new injectors, new ecu, new air flow meter, checked the throttle position sensor, checked fuel pump relay, new fuel presure regulator, compressions perfect, ignitions good, no vacuum leaks, downloaded the fsm but that hasn seemed to be any help. Anyone have an idea whats wrong with it? Any help would be greatly appreciated ive been stuck with this problem for some time now and just cant seem to find a solution

 

Jump the fuel pump test connector (yellow two pin connector at the passenger shock tower) and see if the car continues running. It sounds as if the fuel pump is cutting after startup for some reason.

Check the fuel pump circuit wiring. Note that it runs through the AFM, so check the AFM connector.

Can you keep it running with the pedal or does it just start and die regardless?

 

Ya,Check your AFM(air flow meter) connector and make sure the AFM is plugged in.
If the AFM is not plugged in the car will start up and die..until you plug the AFM in.
