Died, won't start, pulled some codes.

[JaimeG]

Truck died while on the road, now it cranks, but won't start. I pulled some codes, but where do I start?

These are the codes. I'm thinking ICP sensor? I checked the ficm and it reads 48v. The secondary filter is getting fuel.

P2285 C O R Injector Control Pressure Sensor Circuit Low
Default open loop control - underrun at idle, ICP is less than
0.04 volts.
ICP circuit short to ground or open, defective sensor





P0299 C* Turbo / Super Charger Underboost
Fault sets when the difference between EP and
commanded EP exceeds the limit for > 30 seconds.
Faulty EP sensor, VGT control valve slow to respond, Stuck VGT
valve, faulty PCM.





P0404 C* Exhaust Gas Recirculation Control Circuit
Range/Performance
+/- 0.10 EGRP error from commanded to actual EGRP during
normal driving conditions.
Faulty EGR sensor, valve or PCM integrity of EGR position circuit.





P0562 C* R System Voltage Low
PCM voltage less than 7v - cause of no start/misfire.
Low VBAT, loose connections/resistance in circuit, Vref engine
concerns.




P0611 C* O R Fuel Injector Control Module Performance
FICM memory fault will set if a RAM or ROM fault exists.
Loss of FICM power or other internal FICM failure.




P1335 C R EGR Position Sensor Minimum Stop Performance
Fault sets when the EGRP closed position exceeds the
maximum limit at initial key on.




P1378 C O R FICM Supply Voltage Circuit Low
FICM detects logic power low, less than 7 volts. Low batteries, loose connections/resistance in circuit, defective relay.





P2290 C O Injector Control Pressure Too Low
Default inferred ICP is used, ICP is below desired pressure
See diagnostic manual - ICP system.




P2291 C Injector Control Pressure Too Low - Engine
Cranking
No start ICP is less than 725psi/5mpa.
See diagnostic manual - ICP system

Anyone out there?

Looks to me like you got some bad batteries or alternator. Not enough voltage for PCM or ficm, plus I don't see actual icp data, but the code says low pressure which would indicate to slow a crank to start or else a faulty icp. But if you cranked it until it died then it should throw those codes. Get a good crank then throw it on a scanner, and see what numbers you get.

[JaimeG]

Ok, so I just charged the batteries up and replaced the icp sensor. Cranked it but still won't start. Checked for codes and all previous codes are gone.

you may not want to hear this, but could be chaffing of the wire harness. Fuel injector harness. I had this happen, and it is the most mysterious thing to troubleshoot. Try looking at that, namely the driver side of the harness.

will it start if you unplug the icp sensor?

[justinmix]

The ICP codes are a little strange. That would seem like an ICP sensor issue. But they should have popped back up. Try unplugging the ICP sensor and see if it will start.

I doubt it will though. I would guess you have a high pressure oil leak. That would be the reason for the p2291. Especially if it just shut off on you. Next thing to do would be to moniter ICP pressure and see how much psi you're building during crank.

Well it's not the truck in my sig, its a relative's truck, I went over tonight and he took it to the dealer, so we'll find out what it was on Monday.

Turns out it was the IPR.
