The other night after i was giving a friend a ride in my car, I noticed on the way home the check engine light came on and it was running alittle more rough than usual (cammed stroker).

I checked the codes and I am throwing P0200 injector circuit code.

YES I USED THE SEARCH. Most everything i found pinpointed some wires rubbing as an issue. Well I looked around at all the wires and found nothing, plus my wires dont rub there anyways.

So I cleared the code and it seemed to run good for a day but then it came back the next day. So I went to my dad's to start checking different things. This is what i found out.

All of the injectors have power, all of the fuses are good, And all of the injectors are good. The problem is one of the injectors is not getting a ground signal from the computer (tested with a node light). I dont know if it is at the ecu or what. If anyone has a pinout i will check to make sure that the ecu is sending a ground signal that way i can go through the trouble of tracing the line the whole way to the injector or see if there is an issue with my computer.

Also we just had a hurricane i dont know if water can get into the computer and short something. Also i wanted to know if anyone thinks that the computer is the problem, or has any insight into this problem of no ground signal from the computer. Thanks for the help guys.

 

I fixed it. close thread.

 

That was quick. What did you find?
