Need help

[J White]

Long story short I left ts last night in a hurry to get to the er for my son he's ok now thankfully...but my truck wouldn't start so we left it. Went back today and it fired right up.. Drove home 15 min shut it down and now she won't start my sct is pulling these codes:

P2291 icp too low
U0306 software incopatibilty with fuel injector module
P0403 egr control ckt
P0405 egr a ckt low
P1000 obd system readiness test not complete

Any help would be grateful...

What year? I'm assuming hot start issues. So if its a 05+ it's either dummy plugs or STC fitting on the back of the pump.

When it gets hot they leak more and it can't build enough pressure to start the truck. Pretty easy fixes.

Oh sorry it's my 03 with the mods in my sig

The u0306 from what I've seen normally comes from ficm tuning. The p1000 is nothing to worry about. The egr codes are probably ok, from the egr delete I'm assuming. The icp is the worrisome one. Most likely a hpo leak somewhere. Unplug the icp sensor when it's hot and see if it cranks. That will default the sensor and for te most part will let you know if that's bad or not.

So if I unplug it and it starts then its bad? The icp..

You have a ICP leak, (P2291) you will need to air pressure test the HPO system to find your leak.
