No start after has been drove and warmed up good

[Justinfranks]

This thing is driving me nuts. Starts up perfect the first start of the day. When you let it warm up good and drive it about 10 miles and turn it off, it won't start back. Let it sit and cool for bout a hour it barely starts. It runs perfect when it starts. I'm getting a p2290 code. Injector control pressure too low. Do any of yall know where to start with this problem?

ICP Sensor is most likely bad i get the same code when mine acts up but its not all the time its only when its cold out for me but it shakes going up hills. look up ICP sensor symptoms warm no starts is one or warm hard starts. also could a bad IPR. i'd look ino those first i know i read that if its the ICP sensor unplug it when and see if your problem goes away. thats all from things i've read on here and other forums and what i've experienced myself.

Mine is a 03 so it's the one that's hard to get to isnt it?

i believe its on the mack of the motor under the turbo but i'm not positive. that may not be your problem but from what i've read and from what i know of people with the same problem it was one or the other icp or ipr

K. Thanks man. I'm gonna switch that out soon as I get the chance.

you dont even have to switch it i believe you can just unplug it and try it out because the computer will take over and if that solves your problem you know thats what it is the icps are known to go bad and also know to leak oil (Ford tech even told me that) and if you get oil on the wiring harness it will do it too on ebay the sensor and pigtail are $89 for the 04-07 i think the 03-04 are $110 but form ford just the sensor is $200+

I unplugged it . Now it barley has any power and eventually dies and no start.

did you unplug the ipr or the icp the IPR is on the HPOP cover and the ICP is on the head it sounds as if you unplugged the IPR which opens and closes to control injector flow, if that is no or nc (normally open or normally closed) idk but it sounds like HPO leak. you may need dummy plugs, standpipes, Injector o-rings, or a STC fitting also the 03 has steel braided lines that can develop a pin hole causing warm oil to leak to fast to build the necasary 500 psi to start get a hold of a good scanner to monitor HPO pressure and IPR duty that should point you in the right direction
