Re: Injector issue with 1990?
Hmm after doing quite a bit of research I came across a thread with the exact same issue and same symptoms.
SES light stays on, fan on. Throwing the same code (c41) turns out to be the optispark /distributor. Will begin to look in this direction http://www.corvetteactioncenter.com/...e-9-h72-6.html |

Re: Injector issue with 1990?
The LT5 in a ZR-1 does not have an Optispark.

Re: Injector issue with 1990?
Oh right, I assumed the LT5 used a similar distributor to the LT1.
If that is the case, I am still leaning towards a bad ECM. |

Re: Injector issue with 1990?
ECM's, while known to fail, particularly if they get an electrical surge from a high powered charger, usually are rather robust in a C-4.
I would suggest searching for a faulty wire first. You and others have been doing a lot to that car recently, so it is not impossible that the ECM took a dump, but I would rule out the higher probability causes, such as loose connectors, shorted wire etc. You will likely have time to perform those checks as an ECM may take some time to locate. Let the FSM be your friend and follow it's diagnostic protocols. Good luck and keep us posted. Marty |
