no fuel :(
 

i have an 88 rx-7 and im not getting a signal to the injectors i changed the main relay main fuse and fuel pump but it rarely turns on but only for a few seconds i dont know if it could be the harness or the computer or something else:confused:

what rarely turns on.... the fuel pump?

common rx7 problem:

I dont know how you came to the conclusion that the injectors arent doing there job..... BUT I would highly recommend checking your AFM(hooked to the bottom of the air filter box) if it goes bad the car will start for a quick second than immediately stall, it cuts off the fuel pump when it doesnt sense airflow...

tap your tank,probably just a short

You can also locate a yellow connector in the engine compartment by the passenger's side and close to the pressure sensor. You can jump it and see if the fuel pump comes on. Good luck!
