no injector pulse

[dstredi]

A few weeks ago I posted about my problem with injector pulse. Since that post I have wired in a different harness and checked all powers and grounds and I see no problem. I have spark and fuel pressure but still no injector pulse. I believe the Ecu is not getting the signal to ground each injector. I would like to know what controls the information to the Ecu?Is there an online manual That tells what the values of the varius imputs are? I wander if any other Nisson built in the U.S. has simular values. I have access to Allldata. Thank you, Dan

There is a link to the FSM (Factory Service Manual) in the FAQ.

How did you check for spark?

Do you have a resistor pack wired in?

Do you have 12v+ to the solid colored wire on all the injectors with the ignition in the ON position?

Do you have the start signal wire hooked up?

When I first installed this system into my roadster the engine fired up. As I worked on the car over the next week I developed the injector problem. The first harness I got had the start signal wire removed. In reading the forum last week I noticed a mention of this orange wire but dismissed it since the engine ran without it before. When I read your post I went and hooked up that wire and my problem is solved. I have been a master tech for over thirty years. We are never to old to learn. Thank you very much. Dan

I agree with you in the fact that we are never too old to learn, but is getting pretty tough to learn the young . Congrats on your re-repair....
