No start
Had this in 911 section with no responses so figured I try here. Post is lengthy and I apologize but all info is there I'm just missing something and don't know what it is.
Need some help y'all. Wife pulled in driveway nose up little less than 1/4 tank of fuel. Check for fuel in fuel bowl and it fills rapidly. Checked oil all is good connected AE with following results FICM information for sync (Bit) (0-1) = 0 FICM Logic Power = 12VDC FICM Main Power = 47VDC While Cranking FICM Vehicle Power = 12VDC Camshaft Position Sensor Level (Bit)(0-1) = 0 Injector Control Pressure = 1164-1178 Injector Control Pressure Desired = 1178 Injector Control Pressure Volts = 1.46-1.56VDC Injector Control Pressure Regulator (%) 40-41 Everything looks good however it won't start no smoke or anything. No codes at all. Am I missing something? Is there a fuse that could cause this? Need help fast as truck is in in-laws driveway blocking their second car. Thanks in advance for any and all help. Ok guys had the truck starting and running fine now she's bad to a no start again. Reading RPMs while cranking however watching the camshaft position sensor the bit 0-1 goes from 0 to 1 after 15 seconds of cranking. Got good fuel pressure not sure what it is but pulled test plug and held finger over hole and pressure blew finger off. Also the only time FICM sync went from bit 0 to bit 1 was once truck was running. This thing is not making any sense. Also checked ref. volts and it was a steady 5VDC. Any help would be greatly appreciated. |

Not sure when you're getting you're IPR reading but that seems low while cranking.

The IPR reading was during cranking after 45 seconds to one minute. I just replaced IPR about a month ago. What should it be?

You mean there is no one that can give me any more help or any info on what my IPR should be? Thanks for the help

Even with the oil pressure I'm getting could this be a HP oil leak stand pipes and dummy plugs are original

Air up the HPO system using the ICP (passenger side valve cover) sensor plug hole. Try unplugging the ICP and see if it starts first.

Tried unplugging IPC sensor last night still no start. What size is the IPC sensor fitting so I can air up the HPO system. Thanks

m12x1.5. You'll have to close the IPR by supplying it 12v or by grounding pin 2 on the second connector of the PCM, but to be safe, just supple 12v to the sensor.

OK, before this get too far away from the problem, let's look at his initial post:
Quote:
What is RED. He has no sync, so no start. It is probably the plug at the CMP sensor. Start trouble shooting at the camshaft position sensor. Check for continuity. Do the same for the crankshaft position sensor and wiring. Both of these can get corroded. I believe if the CKP is no sync, the CKP is generating no signal, the IPR will default to 14% and ICP will be at 300psi (not 100% sure). BTW, you have to crank it to get sync.

I was wondering about the cam and crank position sensors but wasn't for sure what the 0 bit on AE ment one of the will flash to a 1 while cranking. At 10:00 pm I gave up at work now will check tonight and let y'all know what I find. Thanks for the help
