Hey, i've got a 2003 F-350 6.0 that won't start. I've checked the snap connect oil lines to make sure they haven't came lose. The code that i'm getting is P2290 for low injector control pressure. Is it the HPOP or is that code for something else, the truck started and ran about 2 miles then died. it took a little cranking but started back up. Drove the 2 miles back and died again, this time it wouldn't start back took a little starting fluid and fired up this time it made it a mile and died and hasn't started back since. Thanks for any help.

Do you have a scan tool that can access the system PIDS? Monitoring the engine RPM while watching IPR duty cycle, and ICP for a minimum start pressure (500) would help to determine a possible cause. Could be a bias IPC, IPR, connector or trash in the screen. Will the engine start with the ICP sensor disconnected?

 

I haven't tried with the ICP sensor unplugged it will be monday before I go back to the shop. Yes we have a new snap on scan tool I think it is the Solus or something like that and we haven't ha dit hooked up yep so don't know much about it yet. I will try to unplug the ICP sensor and post back monday. Thanks.

 

I unplugged the ICP sensor and the truck started good let it run for about 30 seconds, cut it off and started it back. After the third time starting the truck and shutting it down with the ICP sensor unplugged it won't start back. Any suggestions, does that mean the ICP sensor is bad or do I still have another issue. Thanks for your help.

 

If still available, hook the truck up to the scan tool and enter the 'data' stream/PIDS.. Look at the ICP value and crank the engine over.. The value shown should raise 'quickly' to 3.5 MPa-500lbs which is the 'minimum' pressure needed in order for the engine to start.. The ICPv should read about 0.80v while cranking the engine.. If the truck will restart (?),, look and make note of the IPR% value indicated.. Or if still a no start condition, list the cranking values for all, and bring the data back..

 

Thanks for your help. When I get to the shop and get all the info I will post back. Thanks again for the help.

 

Hey I hooked the ICP sensor back up and the scan tool as well. The truck did start back and the IPR% was between 28 to 36%. So what do you think? Thanks for your help.

 

If it needs the IPR where is it located, is it the one there with the ICP sensor? Thanks

 

Being the truck will run for a short time (?) does that include extended idling with a stall? or just stalls on higher throttle/load demands? You may want to continue to monitor the pressure values and look for a drop.. The IPR should be about 24% (30% max idling-heated) heated.. Generally heated oil will help reveal a leak condition as well. Any high % numbers (or ICPv drop) could/would indicate a system leak indicating the command for higher pressure to control injection pressure. Idle ICP should be about 580psi (4000 KPa if shown) and ICPv about 89v.

The IPR is in the same area, and it has a debris screen that should be checked.. It sounds like a oil supply problem and could be a restricted screen, HPOP, or even a base engine oil supply issue for the HPOP..
