Thanks a lot. I took some photos of the snow & a couple turned blue when I saved them, I dunno.
I have printed your diagrams out & have them in a folder.
I have ID the knock sensor wire & repaired it.
From your diagram I can tell the wire to the fuel pump should be signal to a relay.
Likewise the ignition circuit from keyed voltage.
The coil circuit I have ID by matching color, now just to determine what coil I'm gonna use & terminate the wires..
With your help I think I'm close to recovery here.
Working towards getting this baby on the test stand later this week.
Thanks Again!
Interesting to note on these Mercruiser diagrams that the voltage for the injectors & fuel pump relay come from keyed voltage, thru the inj & fpr then to ground inside the ecm, instead of coming FROM the ecm to the inj & fpr. I woulda never figured this out before I burned something up.
