ZR-1 Net Registry Forums - View Single Post - Solution to my misfire problem was a crimped wire to # 1 Injector

I have been trouble shooting a misfire and lean fuel problem on my 1993 ZR-1 for a while. I finally found and corrected the problem.

The wires to #1 primary injector got pinched between the plenum and the injector housing on a previous plenum pull and crushed the insulation on the wires and blew the INJ#1 fuse. I repaired the insulation, but missed that the wire was damaged about an inch further up the insulation. The result was that #1 Primary and Secondary Injectors were not operating.

Here are some pics of the final repair:

Final result, QUASARZ is running better than ever now that I can get to see the result of Phil's Plenum and IH porting.
