Hey Dennis,
Thanx for the message!
I am getting the pulse at the coil, and the wire ECU
wires are plugged into this side of the coil. I'm
getting the positive pulse to the ECU - checked the
wire to ensure there are no breaks.
I'm getting juice via the double relay. But no ground
to the injectors - no pulse, no constant ground,
nothing. I drove the car prior to pulling the engine,
so I don't think the problem is the ECU. I think its
either a break in a wire somewhere or a misplaced or
miswired wire.
Any other thoughts?
