You mentioned that you are getting no cam or crank signal pulse, but then you mentioned engine will start if carb cleaner is sprayed into throttle body. if there is no cam or crank signal there would be no spark.
were there any codes stored in the PCM before it was disconnected? also have you checked for spark fuel and compression on all cylinders?
Have you checked for injector pulse using a noid light?
if so it sounds like you should have everything you need and i would be checking all of the grounds pertaining to the fuel injector system and also all ecm grounds, because the injectors are all controlled on the ground side by the ecm.
Hope this helps,
also if you have found this helpful, please leave feedback accordingly, Thank you
I was just wondering if you got the Frontier running? if so I'ld like to hear what the problem was.
Let me know if I can be of further assistance
the only thing that I know that would affect the injector pulse would be any factory security system.
Any security issues would prevent fuel from spraying to stop anyone from stealing the car.
I hope I have been helpful, unfortunately I am at home right now but tomorrow morning I will have access to some more repair data, and I will try to find more information for you.
If I have been helpful in anyway please feel free to leave feedback accordingly. Thank you
