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.
Any other ideas what I can try??
Thanks in advance!!
