Okay... I found the ignition relay module. It isn't the "emission control" module I thought.
The relay module has 4 wires.
Red= Hot with key on
Black= Ground
White= Output power to coil
Blue= Has ground until cranking for a second, then goes open. Returns to ground after engine stops turning.
My logic tells me the ground from the blue wire keeps the relay OFF , and once the engine starts turning, blue wire goes open and triggers power down the white wire to the coil.
If this is all true, what is the trigger that the blue wire is attached to. I suspect either the trigger on the blue wire is going bad, or the relay itself is the issue. It's a $200.00 part, and I'd really like to know where the blue wire comes from.
