New FICM/alternator/batteries still no start...

Had a no start issue with my 03 ford F-250 6.0. Wouldn't start. Had it towed to dealership and said they diagnosed FICM and low alternator output. Decided to fix it myself based on their $2800 to do the job. When I went to pick it up it did start. Drove it home it wouldn't start. Batteries are new. Charged batteries put in FICM that was redone at FICM repair. Put in a new alternator. Cranked about 10 seconds and started although it took a little longer than expected. Took it for a ride, ran fine....Shut it off in the driveway, went to start and no start. Not sure what to do, on limited funds. Any ideas where to look next, I can't afford the diagnostic tools. High pressure issue, ICP sensor, IPR Valve? Would appreciate any input.

Without acces to live data readings your going to be mostly in the dark and so will we.
A no cost test of the hp oil system is disconnect the connecter for the ICP.
The PCM then uses default settings to start, if it starts and stays running you have a bad ICP sensor or wireing. You have also tested the entire hp oil system if it stayed running the hp system is able to deliver the necessary oil pressure to work the injectors.

Thanks dannyboy....From what I gather the ICP is under the FICM, is that correct? Do I have to remove the FICM again to get to the ICP connector? Sounds like a good thing to try and I really appreciate you taking the time to respond...

You can't afford to not have something at least like the scanguage. It will pay you back. Kinda one of those spend a quarter to make a dollar.

The ICP is hard to get too but if your real limber you do not need to remove anything to unplug it but moveing the degas bottle and the ficm does make life a lot easier.

Unplugging it is a pain but I do it from the top, move the degas out of the way.

Plugging it back in I go from below, is much easier. That is if you have a good reach.

Thanks for the advice folks...I'll be looking into it today. May check out a scangage Kinn, not sure how much they cost but I will check one out. I'll get back here as soon as I figure things out.

Their is very inexspensive set up's that actually us your smart phone as the reader. I have not seen them or used them so thats about as much as I can talk about that.
The scanguage II is not a bad set up. Bullet Proof Diesel sells them all ready to go ( I guess you have to do a bit of programming when you first get it). My brother also runs one and he seems happy with it.ScanGauge II Digital Data Monitor

I run the Edge CTS. Its a spendy little toy but I use this every time I get in. And it can do all sorts of neat stuff. I.E.- you can run a back up camera from it, it can run a EGT sensor, it will remind you to change your oil at a certain mileage, it has a fuel helper and will complain at you when you smash the skinny pedal too much, and a bunch more. Very cool little tool.EDGE Insight CTS Data Monitor
Either way you are way ahead of the game.

Yeah, without being able to get readings or codes it's kind of a shot in the dark. What was your main issue? No starts hot? Does it start when cold? If so then the FICM didn't have anything to do with it. Not saying your FICM was good before, but that wouldn't be the cause of a no start hot.
