00 f250 wont start

Ok I will try and lay it all out there for you guys with what I know I have so far.
Good oil level in both truck and hpop.
Good fuel press and swapped out cam sensors.
ipr koeo is 14.84% while cranking ipr duty cycle goes up to max (can't remember exatcly the number some where around 70 80%)
ipr volts .19 koeo
getting under 20 on the icp reading but other times getting over 1500.


When I unplug the icp I get almost 2k pressure and ipr duty cycle stays at 33 while cranking. still no start.

It has started a about 4 times today and only ran about 2 min the last time it did. Idle got rough and truck cut off.

Situation is was driving fine today then just cut off on me while comeing to stoplight. Got it to start after letting it sit for a bit twice to get me to a church parking lot where triple a towed it to the house. I have ae on it and it has ran 2 here. But shuts off after only bried periods of running.

Hpop , injectors are about a year old. Icp is about 2 years old, Ipr has done this to me about 2 years ago and was swapped out for a used one. I just want to be double sure this is an ipr issue before I order one. Money is tight and want to try and diagnouse and not just throw parts at it.

How's the fuel pressure at times it won't start?

I will have to check tomm for exact reading. I have fuel pressure gauge and it seemed to be fine on fuel press.

[ju015dd]

fuel press is at around 60 psi

just changed out the ipr for a brand new one and still no start. With icp plugged in I get no icp pressure with trying to start truck. With it unplugged it goes up to 2k but still no start............... I am lost and need my truck for work!

only code I get is a 1280 injector control pressure sensor circuit low

Also I have noticed. That with the icp plugged in. While cranking I have only seen a max of 14psi of icp press. Could this year old Icp sensor have puked on me. And would it throw and other codes to tell me.?

[ju015dd]

did some reading. I unplugged the ebp sensor and now truck starts and runs. But with ae hooked up.

With truck idling I am getting over 3k icp press.
And the ipr stays at 8 % and never moves???????? what the heck is going on here????

Icp finally lowerd down to 2700 or so at idle but I know it should be around 700 at idle. I am at a total loss here.
