Load test each battery and check the alternator would be my first things to check.

 

done that both bat and alternator are good

 

When it dies does the glow plug light cycle? This would indicate a vref short or an intermittent open circuit supplying the pcm.

SO TODAY I BUY A ACTRON CP9580A SCANNER / CODE READER 3 CODES CAME UP P1000 U0105 AND U0306 WHAT DOES THIS ALL MEAN PLEASE HELP

 

I would check the three connectors to the ficm. Make sure they are fully seated.

 

check the three connectors to the ficm all good started ran it 4 1/2 hour went to a friends house shut it off 1 hour later would not start left it there next morning started it up drove home would not started 2 hours later put scanner on pulled up 4 codes P0603, P1000, U0105, AND U0306 I AM ABOUT TO PULL MY HAIR OUT

 

The p0603 is probably due to unhooking batteries
The u 03 one is a ficm code--check connections and check for bent pins maybe? May need it reflashed?

Using IB AutoGroup

 

p0603=pcm fault, Faulty connection or fuse block
p1000=OBD ready test probably both battery disconnected it should be up now.
u0105=lost communication to ficm, Connections to ficm from PCM or pin's
u0306=software incompatibility with ficm communication error, where did you get the ficm ? may need to get a hold of Ed down at ficm repair .com

 

FWIW when I first got my 04 and it threw the U0306 code repeatedly I took it to the Ford garage and had them re flash everything to stock. Once I spent the $50 to get it flashed (which came with a wash and vacuum) I haven't had that code come up again.

 

That's a good point the code book does say re flash and he has a aftermarket FICM that's not programed most likely , hell washed and Vacuumed I may have to take my Truck at least once a month for Flashin

 

Took it to a shop? The FICM can be a bugger at times, make sure you hear the Click and did not break any tabs when removed.

 

Double check that when you put the fuses in the fuse box, the blades of the fuse go INTO the slots in the connector in the box. You can slide them in BESIDE the slots and it will make intermittent connection. Check fuses for IDM (FICM) and PCM specifically.

 

put a new low presure oil pump in because truck quit no codes new fuel filters so pulled oil filters very little oil got the low presure oil pump gears out the loabs were pretty tore up put the new one in all back together still no oil

do you have to prim this some way please help

 

Did you check the front engine cover ( where the LPOP resides ) for damage/ scoring?
