1974 Dart 318 crank, but no start (Solved)
***SOLVED*** Wire from ICM/ECU to Negative side of coil was broken right at crimp, but rubber sleeve held it in place without allowing voltage to pass thru.
I know this issue has been beat to death, I've read the posts, watched the videos, and I'm still stumped.
1974 Dart, 318 w/electronic ignition. I drove the car into my garage before tearing it apart, engine was jerry rigged to run stand alone, no ign. switch involved. I just finished rewiring the entire car with AAW kit for A body. It cranks real strong, but will not fire.
Have orange box ICM that was new to get car running. what appears to be factory dist./pickup coil, new coil, new ICM wiring.
I get battery voltage to ballast resistor, both sides, with key on. Don't know if ballast is bad, or because current is not flowing, I have tried 2 different ballasts and both read full voltage on both sides.
I get batt. volt. to + and - sides of coil, and test light only dims while cranking, does not flicker.
ICM box is fully grounded to body, only way to ground more is to weld it.
With ICM harness unplugged, or plugged in, voltage at coil or ballast does not drop. A video said the ICM being plugged in should drop the voltage at coil.
I have quadruple checked connections, and cannot find anything amiss.
I don't have an extra dist., I don't want to remove dist. from engine as it ran to get into garage.
I don't have an extra ICM to swap out, and don't want to throw parts at it. Only part of ignition that isn't new is the dist. and internals.
Wiring is done per AAW, brown wire, Ign. 2 goes to coil +, pink, ign. 1 goes to ballast, along with blue wire from ICM, black ICM wire goes to coil -, green 5th wire is not used, other 2 go to dist.
White tach wire goes to bulkhead, but is not connected, and I have tried disconnecting it, does not help.
Pulled cap, cleaned reluctor and pickup coil contacts, new cap, rotor, plugs and wires.
I don't know how to reliably test dist. pickup, or the ICM to know which part, if any, needs replacing.
