Start by trying to get a scanner on it and let us know if you get any codes. You can also start by testing the FICM.

Unless you get it scanned for codes and live data while cranking by a competent tech your just spinning your wheels and fixing to throw $$$$$$ at it.

Just too many variables that can cause a no start/hard start.

Hey bro... kinda sounds like what mine decided to do today,,,, cranks over fine but won't start... I have a bully dog hooked up to it and the code I am getting is P2291 Injector pressure too low-engine cranking,,,, I know what the code is but I have no idea how to fix it?? sounds like we are in the same boat?? I am wondering if a plugged fuel filter could be the cause of this.... the bully says the last fuel I got is rated d+ so maybe it has plugged the fuel filter,,,, it hasn't been changed in awhile,,,, Just hate to start throwing money at it blindly???? Anyone got an idea?

Mine did this and my fix was a new ICP and sent my FICM of to FICM Repair but it could actually be a number of things. Try unplugging your ICP and if it cranks then thats your problem.

Did not get a scanner on it, but I was able to test my FICM. It tested at 48 volts with the key on, but when I tried starting the truck, the voltage dropped to 17.3/17.4. Truck still will not start. It seems from everything that I have read on this forum, I have found the problem. Is it better to buy a new ficm, or have my redone?

I would sent it to Ed at FICMrepair.com and get it fixed and have it loaded with the Atlas 40 tune while it is there! Even with the tune it will be cheaper than getting one at Ford!

You have an 06, your ICP is on the passenger valve cover. Right nearly under the alternator. In this picture, bottom of photo, center, see the brown sensor? That will be your ICP. Motor build dates after 9-23-03 should have them there.

Edit: the ICP's for the 2 different builds are different. They are not interchangeable.
