ok i wrote a post on here befor about my 89'' 240sx. i have another problem and i think it is fuel. my car was running on 3 cyl.the way i now the is because i start the car and start pulling plug wires off and when i pull no.1 of the idle stays the same. so i put another plug in the wire and it had spark. then we were listening to the injectors and did not here it clicking so i changed the injector and it still would not run. so then we started th car and tested the injector plug for power and it had power.
does anyone have any suggestions????????

Check the other injector wire to see if it getting a ground pulse from the ecu.

The one that didn't have power is supposed to recieve a ground signal from the ecu when the injector is supposed to fire. Thus, with the engine running you should be able to hook up a test light between this wire and the positive battery terminal and see a dim light flicker several times per second. If not then it is likely that there is a break in that wire somewhere between the injector connector and the ecu connector.
