Hey guys, I recently picked up an 83 Z28 that had been dorment for +10 years for a bad fuel-pump. Purchased it at a good price and stated working on her. What I ended up with was a 1 owner 83 Z28 w305 and cross fire injection. After only a few hours, I replaced the fuel pump (yes, had to drop exhaust and rear suspension). Did plugs, wires, oil change, cap and rotor. Both Cross fire injector systems were seized, so I took those apart and cleaned them up.


Fresh gas and battery and she fired right up. Took a while for the injectors to clear out, but all in all, she runs pretty damn good. Spent about a week polishing out the factory paint and cleaned the cloth interior.


The car is untouched, all the way under the hood. I want to keep it looking that was as this car in an investment, as unmolested sports cars from the early 80's are becoming harder and harder to find.


The car runs good, even took around for a 60 mile drive the other afternoon. My problem is I have a CEL. Pertains to the EGR valve. But what I also found was a burnt wire that should have been plugged into the rear of the pump on the passenger front side of the motor. Anyone know where to get this plug so I can splice in another? Other GM cars or trucks that used similar system? Any help would be appreciated as I usually work on Toyota/Lexus products and old mopars. Thanks in advance.
