No start hot

I just put a 4" Mbrp straight pipe on the truck first couple start ups truck fired right up. Filled the truck up with fuel wouldnt start, took a little for the oil pressure gauge to come up, unplugged the icp sensor and got it to fire. The truck starts fine when the engine is cold, will not start hot. I plugged the icp back in and now im getting the code P2285 Injector Control Pressure Sensor circuit low. Deleted it, it keeps coming back. Little history on the truck back in June i put a hpop, ipr, and icp sensor along with various other things. So far been 7 months and no issues. Could lack of back pressure from the new exhaust have anything to do with this? Do i need a tune? or just a coincidence back to having high pressure oil issues? Also considering getting some sort of diagnostic tool any recommendations? Any info would be helpful,

Thank you

Dave

No Start Hot

Just done tis on my 04 6.0 and it can be very mind blowing. This is my suggestion get a ScanGuage II ( I do not work for them so i have no monitary intrest in them ) from AutoZone its $160. Connect it to the OBDII port and got to the ScanGauge site and program in the things you want to monitor. what you want to watch is Sync between the cam and crank sensors, FICM should be between 45 and 48 vols constant, IPR Make sure it is between 15% and below 84% if it hits 84% the HPOP is working to hard to gain oil pressure and check IPC you need at least 500 PSI for the injectors to fire. check it while its hot and wont start. If you have low ICP when hot it is more than likely a leak in the injector nipple cup o-ring or other o-rings in the oil rail. 98% of the time no start hot will be due to High Pressure Oil Leak. any other symptoms???

Just ordered an Sct livewire ts to check my icp and got a ipr socket. The truck is an 05 6.0. Planning on putting air in the motor this weekend to check for leaks
