    Question PMD extension cable,,

    Are these extension cables known for going bad? I am having stalling and not starting problems and I think the cable that is bad. The cable is roughly about a year old.

    I have a home made one 8 years old on the suburban and a bought 3 year old one on the 95 GMC . No problems. Only posible failure point would be water getting into the PCM connection. 94 has the good ignition switch, but the 95 failed, weird, caused first gear only and codes for all of the transmission solenoids failing. Check for codes.

    my extension cable went last year. If I wiggled it near the connection the truck would start. One of the connectors pulled out of the plug. It took a while to find it. Replaced the cable and all i s well.
