no start condition on coyote

3. we put 12 volts to position 5 in the pdb and got crank and fuel pump. with power to position 5, the MIL light flashed as it should, and the fuel pump started. Of course, we found a couple of leaks, but that's another story.

It seems as though we are missing a wire someplace. We don't have power on. We need to determine what wire turns on ignition A and B circuits (i.e. turns the PCM on. with power to position 5, you can turn the key and everything works as it should.

Following everything you're describing except this.

What do you mean by "position 5?" That's nowhere in the instructions and I can't figure out what you're referring to. Maybe related to this, your answer to Mike's question in post #4 didn't make sense to me either. I asked about it in post #11, but haven't seen an answer. At least don't think so.

Maybe to approach it another way, power gets to the PDB in two ways: (1) The large tab on the front of the PDB. That should have a #4 cable from your 250 amp fuse, the other side of which is attached to the hot side of your disconnect switch. Result: Full battery power at all times to the PDB front power connection, (2) There's a second power and ground connector. Item B Connector # C500 in the main harness. The hot side of this connection also needs to go to your battery power. The ground side should go to chassis ground. That's the main ground connection for the entire system. Ford provides a cable between these connections and the battery. 3.5 B + to FPPDB Cable Assembly. But I didn't use it and sounds like you didn't either. But you still have duplicate the connections.

With these two connections (points #1 and #2 in the previous paragraph) the PDB will be hot and everything else (e.g. PCM, etc.) will be alive. Please confirm you have these connections wired as described. With this plus the other connections you've confirmed (pigtail, etc.) it should start.
