I've been chasing down this hard start issue, and am testing each part individually... When I pulled the Dist. Cap to test the coil (Previous Post) I noticed that the terminal leads to the ICM have melted the platic connector. Not good. I assume this means my ICM is heating up and melting the connections. What do you guys think? From best of my knowledge, this will also cause my hard start/rough idle condition if the ICM is heating up which means it's on it's way out. I also need to find a replacement amphanol... Great... See pic... Please comment. Attach file:  IMAG0137.jpg (219.08 KB) |

Damn! That's icky.
The heat in there must be insane. That plastic shouldn't fail until north of 300F! It didn't just get soft, it turned to liquid. A new connector is easy, post this question on the K&B Corvette Products Forum Page. They are our newest Gold Sponsor. The heat... that really creeps me out! |

That could cause some problems!
If you want to replace that, the part number should be: 1986260 (Terminal Block (to elek pkg)) Around $75 from GM. Matthew |

Yeah... I don't think it was so much the heat in that area (Entire Dist.) because the connector right next to it did not suffer ANY damage. It seems that the heat was isolated to those connectors. So that would lead me to believe that the ICM itself overheated on those terminals and the heat was just transferred via the terminals to that plasic. Lucky it didn't cause a fire. |

I went and had the ICM checked at AZ... it tested as good.
Not sure what to think about that. unless this happened previously and the module has already been replaced once. I am going to put heat shrink on the melted spade connectors and leave them like that until I can find a replacement connector. |
