Getting the engine bolted in is about 10% of the way there.
The next 80% can go quickly with help and skill.
That last 10% takes about as long as the 90% that came before it.
hmmm.. im not sure what else to say.
With the ECU and MPI both plugged into the harness. If i apply +12v to pin 10 the only way to get the MPI to function is to ground pin8
Iirc, pin 8 keeps the mpi relay energized once the ecu powers up and keeps it energized until you shut the engine off. That set of contacts also supplies voltage to the engine sensors and ecu. This wire has to be hooked up into the ecu as it supplies the ground to energize the circuit.
