while a helper turns the key to "start" you check voltages at the "point" of the pentastar ECU connector and at the coil positive primary terminal with your VOM & if no fire work your way back to the bulkhead via the ballast & further upstream (under the dash) if need be & can take off the brown "sol" wire at the starter relay to keep the starter from running down the batt if needed.

if BRAKES light on cluster dims but doesn't turn off, then ballast and bulkhead are good, although is something to check.

my 73 duster would start and die...i thought it was the ballast resistor, i traced the problem to the bulkhead connector.

Yes. Same way on my Challenger. When you start turn the ignition key to start, the IGN1 "Run" wire that goes to the ballast resistor (the power for the coil while key is in "run" position) is not hot. Only the full voltage IGN2 "Start" wire that gives extra power to the coil while starting is hot. This is the wire that is connected to the same side of the ballast resistor as the wire that connects to the + terminal on the coil. If you bypass the ballast resistor (say to connect the "run" wire to an MSD control) you will not get voltage while cranking. To fix this, splice the IGN2 wire to the IGN1 wire. Quote:

do you have the brakes light OFF at cluster while cranking ?

make sure that you have a good ground from the rear of the engine to the fire wall too. Very important.
Clean it, if it's Dirty. Oil it, if it Squeaks.
But: Don't fix it, if it Works!

Try swapping out the ECU for one that you know works.

That is correct. You could unplug the ballast and the car should still start but of course it will die as soon as you let go of the key. The ing 2 is the bypass for the ballast in the crank position sending battery voltage to the coil while cranking.
Does the car crank over when in the start position ? Ron
Yes, the car will crank over just won't run. I can set the key to run and fire the car from the relay and it runs fine. I do have a dual ballast wiring harness but just have it hooked up to a single MSD ballast resistor to match my Blaster Coil. Could that be a problem?

Duh
haha Figures. Could I splice the wires and fix them together with a single end and fix the problem or would that just mess things up more?

connect the blue and the brown wires together on the one connector & you're set. (4 pin ECU I'm assuming) EDIT you have the OE double connectors/wiring harness that were on each end of the 4 terminal ballast and you plugged your new 2 terminal ballast into one half of each of these plastic connectors? If this is correct jump the blue to the brown.
