I'm having problems with hard starts and stalling which is intermittent so I checked the ficm with a volt meter and it checked out fine so I hooked up torque pro and here are my readings if anybody can give me some advice on what to check next.
I didn't have any codes and had the scanner on when it did stall and the numbers did not change.
Batteries are new and load tested. Alternator is new and charging.
The readings posted are when hard starting. The truck starts fine when it's hot but may stall when putting it in gear and having the wheel turned hard. (Checked for wire chafing in steering column and it's fine)
Recently had glow plugs on drivers side changed. (Code )
CPS was changed. (Code )
The rest of the item's I need to look into because I don't service the truck and will find out.
Do my readings on the ipr and icpv look Ok.
Also what sensors would you disconnect.
Thank you for your help!
Disconnecting various sensors & components one-at-a-time can often times prove valuable (EGR, EBP, ICP, EOT, ECT, BARO, GPCM, MAP)
The readings look OK, but you don't have a "cranking" set of numbers. At least you didn't indicate that. You stated "Key on" and "Idle". You need to watch ICP, IPR, FICM voltages, Sync, etc when cranking.
Not that was a cold idle.
Tried to get the readings the truck has been sitting all day but it's 65 out so the cranking was short
Icpv 2.4
Ipr 76.2
Hpop started right up couldn't get a pressure.
Key the scanner before turning the key on and record the data while cranking the truck... that's the data Mark needs. Also any data after it gets to normal temp.
I'm using torque pro I don't know what you mean about keying the scanner. I will try in the morning when it's cold.
Engine hot at idle reads.
Fmp 48.
