Crank but no start?

[jcbones]

I've searched the forum over (multiple times) tried all suggestions, but still no start.

2001 f250 4x4 supercab returned to a stock chip.

Codes:
P0603 INDICATES PCM HAS EXPERIENCED A POWER INTERRUPT IN KAM CIRCUIT.
P0230 ???
P0231 Possible ICP fault > Unplugged... full of oil.
P1280 INJECTOR CONTROL SIGNAL CIRCUIT OUT OF RANGE LOW WAS DETECTED.

Problems:

Most days, will crank but will not start.
Some days, will crank and start. If it does, it will crank and start all day.

Checked:

Glow plug relay: good
Glow plug left bank: 64 amps
Glow plug right bank: 52 amps
HPOP res.: full
ICP: needs replacement. currently unplugged.
CPS: new, and rpm showing 100 while cranking.

Looking for possible solutions, next I am checking UVC harnesses (unlikely that both would go at same time). and buzz test. I have no Idea what the KAM circuit is. Maybe something to do with the injectors, or the IDM. All suggestions appreciated.

Bones.

KAM = Keep Alive Memory, i beleive its from disconnecting the batteries.

I didn't disconnect the batteries, but I did check battery voltage.

10.5 volts before cranking.

So, I've put them on charge, we shall see. Interesting enough, both batteries are less than 3 months old.

if you change the ICP sensor, get one from your IH dealer, cheaper than Ford. if you can find an IDM from a wrecking yard ($1100 or so from Ford).

have your checked your wiring under the valve covers?

Couple of days now, report is.

The crimps on the battery cables were bad. I found this by charging the batteries, and it did start. The battery post had 12 volts, but the cable (not the connectors) had 14 volts.

Removed connectors, tinned the cable with solder, replaced connectors. Starts every time now.

The definition of KAM put me on the right track. Thanks guys.
