Hard Start FICM?

[speotter]

So I checked the voltage and the FICM was totally dead. As if the key was off (but I had in on).

When I took off the FICM several wires broke right at the connector (engine side). So I bought a replacement wiring harness. Everything of course had to come off first. All the air tubes, fan and shroud, alternator, belt tensioner, both batteries, the list goes on.

I took off the old harness. Compared to the new harness, the pieces were all the same, but the locations were all slightly different. I could not get the last plug off the rear of the AC unit, so I spliced in the new harness to the old wire. It was odd, because it was a shielded cable (2 wire with ground and foil shield).

I put everything back together. Checked the voltage on the FICm and everything read great. Both batteries, fully charged and reading 12.86 v.

I turn on the key (hadn't been running for 6 weeks), crank the engine and the baby fires right up. Man, did that feel good. I let it idle while I finished buttoning it up, topped the fluids, etc. Then I noticed a couple of clamps were pointed up and poking into the hood insulation, so I turned off the engine and repositioned the clamps.

I went to start it again and nothing, dead as a doornail. not even any idiot lights, no cranking, nothing.

I waited a minute and it cranked right up, as though brand new. I took it for a test drive and it ran great. Took it on the freeway. Got it up to 85-90, just to clean the gunk out.

Parked it and went to drive it an hour later and dead, nothing, like the batteries were out. Except that when you turned the key off after trying to start (no cranking), you heard a clicking sound, like a fuel pump that was releasing pressure.

So is this a sign that the FICM is dead? Why wouldn't it crank? Or did Ford give me the wrong harness? When it was running it ran great and never faltered, so I doubt a bad connection. I was very careful to make sure that every connector had a solid connection and "clicked" into position.

It actually installed very nicely (except that connector that was at the rear of the AC that I could not get to-no clue what you would do if you ever had to actually work on the AC compressor).

Anybody with any ideas out there?
