the problem i have is that my supra isnt getting fuel past my injectors
i have presure in the fuel rail but from that point on no good it starts for a half min because the cold start injector but the injectors doent want to take over so she stalls.

what size injectors are you running? and are their any other modifications done to the fuel system?

and still nothing its crazy because it runs off the cold start injector which starts the car then the injectors are sopose to take over but they dont it shuts off.do you think it could be the ecu thats bad.

or maybe the efi resistor im not sure what these items would cause im just trying to think of some thing.thanks for taking the time to stop bye i really could use some help.

no they are not thats why im thinking ecu.but im not 100% sure.

well, it is either your harness, or your ECU.

I would check where the wiring harness connects to the ECU, if it had an aftermarket computer, such as an AEM, MOTEC, or even an E-manage they may have but the injector wires.
