1987 Nissan D21 Injector issue
 
Hi everyone,

I have a 1987 Nissan D21 with the Z24 motor.

I am having issues with the thorttlebody injectors.

If I have 12 volts going to both injectors, neither of them work, however if I have 12 Volts going to only 1 they seem to work.

I had to bypass the ignition system and run a 12 volt circuit with a toggle switch (to toggle the power on and off when truck is not being driven) to get them to work.

I have tried another computer, replaced the fuel pressure regulator, verified all fuses are good, tried swapping relays out, all to NO avail. :fear:

Any other ideas what I can try??

Thanks in advance!!
