noone has any idea what would cause all of this to happen at once?

 

A low battery or charging system along with a few bad glow plugs.

 

it turned over fine but, i put jumper cables on and let it charge a while then tried it with the jumper cables still on and no difference. i thought maybe the glow plug harness had come loose since all the codes are on the same side but i didn't see any obvious problems. i'm at a loss with this thing

 

update:
glow plug harness came unplugged but still no start. about to check codes again

 

Unhook both batteries and hook the +/- together after both batts unhookked, check bother battery voltage and charge and get batteries tested, clean any corrosion on the cables. Pull your small fuel filter and make sure you have fuel there. After batts are tested good and charged up or replaced run the glow plugs but dont start 3 30 sec cycles. Start the truck then deal with the glow plugs

 

another update, fuel filters are new, theres fuel at the 2nd filter, batteries seem fine and turns over fast like it should, no corrosion on the cables. codes p1378 and 2268 are still there though

 

Gonna have to get a scanner and check icp and start narrowing down possible problems. I use torque $5 plus a cheap bluetooth adapter

 

i have a mac mentor scanner i'm using to read codes, started raining so i had to call it quits for today maybe tommorow

 

Just unplug your ICP and try to start.

 

2268 is the code for water in th HFCM. 1378 is a code for low voltage on the logic side of your FICM, this can be from bad connection or low batteries.

 

no change with the ipr sensor unplugged, connections seem to be good on the ficm.
haven't had time to do much more with it working 7 days a week

 

swapped in a known good ficm just to see if it made any difference, i finally got torque pro on my phone, the highest ficm power side voltage i saw was 41v and the logic side 9v. both sides quickly fall once i start cranking it over, what am i missing here? i'm gonna guess this is gonna end up being a wiring problem

 

That reading is with the "known good FICM"? Low voltage in batteries is my thoughts.

 

yes, with the known good one, i tried hooking jumper cables to see if it'd help any but no change, could the batteries be that bad? i haven't checked voltage at the batteries but iirc it said 12.6ish on the torque pro app

 

As others have recommended. get the batteries tested with a good load tester at a battery shop or an auto parts store.

 

batteries tested at autozone and checked out. any idea where to go next?

 

Might check the batts with a multi meter then compair to the reading on the app, i think there is also a volt reading at the ecm in the app, they should all be the same or close to it, i think you can also check the volts with a multimeter on the ficm itself but you have to be careful. As far as fixing that if your reading are off im not sure, might check the ficm connections.

 

If your batteries are good and if the known good FICM didn't help, then I would look at the FICM relay as the next most likely culprit.

 

Check your FICM ground.

 

gonna pick up a relay sometime this week when i can get by ford to grab one, where's the ground located?

 

new relay and checked grounds and no change. i looked at the harness but didn't see anything obvious. not sure what else to do with this damn thing

 

I would still be looking batteries. Don't trust a autozone test.

 

With logic voltage that low, I'd start looking at batteries. They are either bad or have bad connection. Check voltage with a multimeter with key off and while cranking. While cranking, voltage should not drop below 10.5 volts or so. Anything less, replace batteries.

If they come out good, then check FICM logic power at it's source as follows:
Check Engine compartment Fuse 5 (50A) This should show battery voltage at all times.
Check Engine compartment Fuse 15 (15A) this should show battery voltage with the key on and FICM relay energized.

If you have battery power at those fuses, but you still see 9v on your scan tool, then it's time to check some wiring. You'll want the FICM connector closest to the front of the truck, and check continuity between pin 8 and the fuse 15 (wht/blk wire).

There is also a 12 pin connection that should be to the right of the driver side battery as looking from driver side fender. Pull it apart and look for corrosion and a tight fit.

 

i assume you mean the connector between the the battery and power steering reservoir?

 

Yes that would be it.
