I checked the timeing, all the grounds and tested all the sensors, also replaced the ecm with a known good ecm. But I think I got it. Below the mixer on the right side of the unit is a cap. i removed the cap and threr was a align screw there which adjusted the air fuel ratio. Useing the computer i was able to bring into spec, and thank you again for all the help.
Had one the ecm was going out.Started popping on occasion then finally just wouldn't take fuel.
thanks i'll give it a try.
I've had some Nissan motors act like that when the ignition timing was advanced a bit from where it was supposed to be.
