Been a while since ive been on but these days i have a 05 F350 6.0, had for 5 yrs or so now, but having real start issues, cranking but no start, showing all decent numbers that I can see, my torque app showed a bit after that the cam sensor, di so i did that, with a motorcraft replacement, with a bunch of tearing in to swap out tht lower rad hose too, and now she cranks with no start, even when I put the old one back in, when at first with the old one, beofre doing anything it just ran like crap.
new ac delco batts 1 month ago
new fuel filters, fuel at bowl
ficm above 48, ficm power 11. and higher
hpop 1500 and 1600 when cranking
IPR at 52, 73 another time
my coolant/ oil temps for many miles have been average of ten apart.
I unplugged the ICP and nothing, no oil built up in it either.
I looked at the ficm plugs and they were fine (kinda sure) but as I lifted more the front one came off, one side connector was gone and the other broke right then and there, since i was having start issues and not thinking that connection was a problem initially, i tie wired that tight to keep looking for other issues, not 100 percent sure at this point.
I had some glow plug codes but even with truck plugged in and heated up to 100 degrees she came close today to firing up but not quite.
Shes almost firing up but just doesn't, thats more than just the cranking for a few days.
I see the rpms coming up a bit when cranking maybe 200?
the oil press on left of console goes up after cranking for a bit, maybe half.
Last night I got a pid to see the ficm sync, it stayed at zero..
i cleaned the block area, the new cam sensor is a motorcraft, I had replaced the pigtail as the clip had busted on the connector, right now I am wondering if its that.
is there a way to test that pigtail connector?
If FICM sync is zero it ain’t gonna start. Either the plugs you mentioned aren’t allowing connection, the FICM is bad, or something else isn’t allowing it to sync. In my case a bad cam position sensor was causing no FICM sync and wouldn’t allow my truck to start.
Can you pull up cam sync? If your old cam sensor was leaking oil into the connector it may not be getting signal from the new sensor. If you ARE getting cam sync but still no FICM sync I’d guess the FICM plugs since they already pulled out on you.
Thanks for tips I added the pids for both syncs,
Dig this cranking test today, all good numbers, except no syncs, 1st test I had revs too,
then as I screenshotted another test I didnt notice I had syncs, but no revs?? wth?
the syncs never came back, I think im looking at ficm or the front connector to it... dang it, not having neiter syncs would eliminate my pigtail on the cam sensor I suppose.
The cam sensor is a motorcraft.
9 volts battery voltage is really low. Charged batteries at start should be 11-12 volts. I would fully charge your batteries and load test them before going forward even though they are fairly new. That is probably the reason for low crank rpm.
I have heard low battery voltage may destroy FICM module, but I am not sure, My batteries when low on my 04 f350 6.0 and I started losing 48 volts out of my FICM, presently rewiring new FICM connectors into the harness as the connectors clips are broken on all three connectors, and I got a low voltage alarm to wire in, .. At this time.. all I have is done is gotten the first connector replace.
Okay, some new up dates, I plugged the truck intoday to warm it up, even though its not cold out, maybe 50s, the syncs come up with rpms, didnt realize this,
ive been turning up the batt charger to get more power in there, so cranking is up on the rpms
as I went i eventually got a p2285 code, I unplugged and it sounded different cranking, but no start, tried more than a few times.
Can the IPR be bad even though my Press numbers bounce around, its not like they are always in the same spot, like a bogus read.
no oil in the ICP when i look with the connector off.
Id have to think with good press numbers and not crazy IPR numbers im in a good spot, I dont get it,
Ive moved wires around a bit more and looked but i dont see anything out of the ordinary...

The next step is to verify you have a fueling command (injector pulse width). It is issued by the FICM when both syncs are achieved and you have proper "starting" conditions.
From the data shown in your link above, you have proper ICP pressure, proper system voltage, proper cranking speed, and both syncs. Lets see if the FICM recognizes all that!
