Hard Start...FICM?

[03 tx pwr stroke]

Truck is hard to start when cold. No codes, no white smoke. Once the truck is warm, no problems, fires right up.

Vid is after truck sat for 13 hrs. Temp was 73*.

What does the voltage read?

Haven't had a chance to check it yet. Was just trying to get ideas. Gonna check it In a day or 2.

I can't get the vid for some reason.. Normally poor cold starts = Bad FICM or injector spool valve sticktion or your glow plug circuit isn't working properly..

A buddy told me possibly glow plug circuit. Any way to test that?

Tested the FICM. 48.6 volts key on engine off. 48.8-48.9 volts key on engine on. Next?

Glowplugs- I was told to pull them and ohm them to ground, I believe its about 1ohm is normal. Someone else may need to chime in.

Glowplugs shouldn't be an issue at 73*, but if you want to check them...

All of the specs I have posted here: http://powerstrokearmy.com/forums/showthread.php?t=25432

What was FICM voltage during cranking?

How old are your batteries? I'd highly recommend having them load tested, weak batteries will simulate a dying FICM, and in theory it's said they will kill the FICM too.

Is it puffing smoke on start up? What does it smell like?

Voltage during cranking stayed at 48.6.

Batteries are fairly old, but I had them checked out when I replaced the alternator last year. Tested good. I get a little white puff when I first start it in the morning. After that, no more puffs. Haven't smelled the puff as I'm the one that usually is starting the truck.

on one of our trucks the hard starts were a two fold problem. one was failing injectors (really bad stictition) and we also had a bad high pressure oil leak under the valve covers. i think it was the stc fittings.

Wouldn't suprise me if I had the oil leak. Looks like just about everything that can leak oil IS leaking oil....C'mon tax time....(going to PSE for several things)
