Crank/no start

I have a 2003 F250 with 157,000 mile. Left the house last week and got about a mile down the road when I realized I had forgotten something. Pulled off to turn around and had no power to get back onto the road. RPMs wouldn't go over about 1500. Finally got it on the road and it completely shut off. Was able to get it home and have been tinkering with it. Stats from Scangauge are as follows:

Key on not cranking.
IPR 14.81%
FICM 47.6-48.0
Sync=0
ICP 32

Data while cranking.
IPR 43-47%
FICM 38-42
Sync=1
ICP 1532

I'm leaning towards a bad FICM but the ICP pressure seems to be high to me. Any thoughts or suggestions.
Thanks in advance.

At 32V until the FICM is fixed I wouldn't worry about anything else. Or try to drive it again, you can damage the coils in the injectors at voltages that low.

What are you using to read data with? If the ICP PID you're seeing is desired, you need to find either ICP_V or ICP actual.

I'm getting my reading from a Scangauge. ICP voltage starts at .29 then goes up to 1.98 when I crank.

ICP is reading high, I'd tell you to pull the connector to check with it unplugged but you need long and kinfd of skinny arms to do that easily on an 03. Are you getting a fuel pulse width reading above 0?

Which sync did you code in; cam/crank or FICM?

FICM SYNC
TXD 07E02209CD
RXF 0462050906CD
RXD 3601
MTH 000100010000
NAME FSN
KOEO = 0
Engine on or cranking = 1

Camshaft & Crankshaft Sync
TXD: 07E02209CD
RXF: 0462050906CD
RXD: 3000 (3001 alternate)
MTH: 000100010000
NAM: SYC
KO=0 LI=1 HI=1 OR 0-1 (NO/YES)
1=in sync, 0=not in sync)
