 Hook up a battery charger and turn the ignition key on for a half hour.Then turn the key off and then try to start it.Did you install the prom/memcal from the old ecm? The extra wiring that is cut is likely from an old remote start installation.

Reply to Davo/diablo666's Post: davo,
sorry for the wrong info. actually, i installed ingintion module
(under distributor cap and button)
i think the black wire is cut now because the positive battery terminal is getting hot. (shorting?)
once again, on the back side of module, a 3-pronge connector with cut black wire in same pronge as red wire.
on front side, 2 2-pronged connectors. when these two connectors were removed, plastic clips broke off. i also need to know color diagrams for these 4 wires.
i'm willing to pay more for correct help because
repair manuals do not show wiring.

 You should be able to trace what wire you are saying is cut now that you know which goes where.

Reply to Davo/diablo666's Post: i can not accept your repair advice because the wiring diagrams sent were incorrect by the fact that not all wiring is shown. due to this, when wiring the module incorrectly (by diagrams) my whole distributor now needs replaced (FRIED!!)

thanks for your effort, but no deal on the $$.
