Hi All
I had a strange failure with a new ignition module yesterday
it is running on a 1227747 with the stock coil
I put heaps of heat paste on it but the car popped at high revs then a minute later stopped and would not restart.
I checked the coil and initially thought it was that but fitted a new coil and it did not help.
hooked a noid light up to the coil power and signal from the ignition module and I had no pulse.
the strange thing is I still have injector pulse.
I have disconnected the 4 wire plug that goes to the Ecm and still have no spark.
I disconnected the tach and still no good.
I am pretty sure the module is cooked but was concerned something else caused it but all the wiring checks out ok.
is it possible a tacho could burn out the ignition module?
The engine is a v8 and in a car that was originally a v6
I am using the stock v6 tacho with a Dakota digital tach converter to change the pulses for the tacho.
the dakota module part number is SGI-8 E.
