I just had my 1997 SOHC Neon worked on and the dash cluster died the other day and now I have multiple codes.
misfire #2 cyl.
misfire #2 ing.
low voltage fuel pump
injector ...(one also)

The mechanic thinks it is the PCM. A buddy of my who is a mechanic thinks that there may be a ground wire issue causing the codes. Does anyone know where the grounds are?

 

cant remember them all off the top of my head but i can remember two. one goes over your radiator and connects to the support and the other one either goes from behind the head to the passenger fender or from the side of the valve cover to the passenger fender

 

And you have the main one that goes from the negative battery terminal to the block. Usually its on the front side of the engine under the starter somewhere.. just follow the wire..
