Default Re: Help needed: Code 42 - Electronic Spark Control Error

Okay, I'll try to get to the Post Office at lunch. Not looking too good as a major redecoration project at my job is going sideways, and fast!

Yes I had a 42. It was the bent pin preventing proper communication(?) or preventing the ECM from knowing that the DIS box was 'there & willing to work'? I'm not sure which, but the result was the ESC box and the starting protocols in the ECM took over management of the ignition system. The result is a somewhat sick LT5 with useless extra fuel injectors!
