2003 3.1L Fuel Injector Wiring Harness / No Start

[peon]

I'm having a no start issue and narrowed it down to the Fuel Injector plug harness. I was looking for a wiring diagram for that harness and/or the plug specifically. I think A-H is all the Injector signals but I'm trying to figure out which signal would kill my Tach and not fire the Injectors. I can wiggle the harness by the plug and all works but I need to find the bad hot or ground. I think the opposite side of the plug is the CPS and the MAP sensor but I can't find anything on the Green and Grey wires. Thanks for any help.

id start with taking that tape off them wires, if they are or have been spliced they could be the issue.

The tape just covers a bare spot in the wire. I checked it out and it appears to be ok.

To follow up the wires going to the CPS was the problem. Melted together. Took upper intake off and removed plug. Cut bad section out, soldered, heat shrink, and back in business.

a bare spot is not ok.

what happens is air gets to the wire, then kills the wire. when that happens you get whats known as dry wire, basically the copper wire is now tarnished and no longer can flow a strong currant through that part of the wire.

so its best to just cut that wire where the bare spot is, then strip the wires back till you get clean shinny copper wire on both cut ends, then solder and shrink tube the connection. so its air and water tight.
