Never got to work on it anymore today. Got my buddy coming tomorrow with the Ford IDS system. We'll run all the diagnostics from that. Hey Cheezit, can the IDS test the FICM and give me the voltage readings?

There is no fuel pressure sensor. That's one of those things you have to do manually with a gauge, which will also require some kind of adapter to screw into the fuel test port on the secondary fuel filter housing. Maybe your buddy has one of those too, at least to test the pressure.
IMHO that's one of those gauges that everyone needs anyway that's a little expensive, but cheaper than injectors or a fuel pump.

OK, got 48V on one and 12v on the other two. The two 12v drop off after repeated cranking. That normal? My friend couldn't help me today after I picked up the IDS, so I'm flying a little blind. The self test checked out OK, only had a U1900 from the TBC. It did flash "water in fuel" on the dash and on the computer when I ran a couple of self test, but I do believe those are exactly that - just the system testing itself. Guess I'll p/u a fuel pressure gauge and see what's up with that. Have another fuel filter to put in as well, although the old one only has 10000 km on it.

Read more through the FICM diagnostics and looks like everything is good there. The other two voltages drop to about 9 volts during continued cranking, and I've got FICM Sync. So for all sense and purposes that thing is working. Next, and probably should have been first check - fuel pressure.

OK, fuel pulse width is "0" while cranking. What gives the fuel pulse signal? I assume that it is the FICM, but what is the trigger?

Good evening Cheezit,
This was during the last crank test I ran. DTC count is one, but it's the one for insufficient run time forgot the number and it's not on the recorder. Voltages were a little higher first couple of crank attempts tonight. Haven't been able to test fuel pressure, can't find suitable fitting to tie into the test port. Tried ICP disconnected and it made no difference.
ICP_DES is 1452.83 psi
ICP volts is 0.57v
FICMSYNC - Yes
SYNC - Yes
FICM-LPWR - 10.5 Volt
FICM-MPWR - 48.5 volt
FICM - VPWR - 10.5 Volt

Thanks for the quick analysis. Being an 06 model where would you start to look first? The sensor looks perfectly dry around the outside. Most write ups are for older style with the sensor under the turbo.
