Hi there!!!My vehicle: 2005 F250 6.0 Powerstroke Superduty Lariat Im new to diesel engines but have a little understand' anyhow heres my problem. i recently changed all injectors. prior to change truck ran fine all except for a hiccup due to cylinder #3 contribution/balance dtc. After replacing injectors truck will not start. Batt: 12.5v KOEO.. 10.5 crankFICM 48.00 KOEO.. 48-48.548-48.50 crankICP 0psi KOEO.. 1400-1600psi crankPulse Width is jumpy between 1.8 and 6.3 during duringIPR 14% KOEO.. 84% crank
Additionally when cranking it acts like it wants to start but won't turn over. Oil pressure is good fuel pump is good.
I'm at a loss I've checked multiple forums and have tried what was suggested in them to no avail any and all help is appreciated. Thank you
You have insufficient ICP pressure. The pressure values you are reporting are likely to be assumed numbers (ie not real). To know the real numbers, you need to monitor the ICP sensor voltage output.

What voltage should I look for and also how would I check that voltage?
The tool I have only allows me to monitor pulse width and the icp (false readings)
You really need to get a good scan tool - anyone who owns a 6.0L needs one.
.85 volts is going to be about the minimum sensor voltage output to start. Personally I wouldn't mess with trying to backprobe sensor contacts to see the sensor output - just get a good scan tool. FORScan Lite for a smartphone is very good and pretty cheap. Torque Pro is pretty cheap also. You want a scan tool that reads codes thoroughly - tuners can't do that.
That said, it seems that you are heading for an air test of the high pressure oil system.

I am not sure how a bad FICM connection can result in an 84% IPR command when cranking, but anyway - As Benny said, glad it is running again.
EDIT - I guess I spoke too soon ............

So from the last post above to your other thread in only a few minutes, or I guess I am misreading the post?? Maybe you only meant that you solved ONE of your (several) issues.
