Last night my 2006 f350 diesel died while driving home after an alignment. Had fuel but acted like it was starving. Lift pump is working, fuel in secondary filter. Got it to run on ether but like no fuel from secondary filter unhood to the motor. Please help.

 

Don't use ether unless you want real problems. Do you have anything you can read live data with?
Does it turn over? Does the dummy low pressure oil gauge come up?

Yes, have a code scanner. Yes it turns over. No dummy light. Its just like its getting no fuel

 

What is the icp, ipr, and rpm when cranking? Also what are the ficm volts?
As far as the dummy light--what I mean is the low pressure oil gauge--does it come up (the needle) just trying to eliminate hpo. If no hpo no fire.

You need gauges to get live data

Do you have low pressure oil and Fuel. You've confirmed fuel.

Unplug the icp and truck goes into default mode and bypasses the icp if it runs with icp unplugged, it confirms a bad icp or icp pigtail.

Search the tech forum and Rusty Axlerod has a thread that describes the various scan devices to get live data. Price rabges from $25 to $300.

 

Thanks. will get more info after work

 

Where is the ipr, please

 

It is on the DS of the HPOP right behind the turbo.

 

No oil pressure. So you say no hpo, no fire. So I'm guessing have to replace high pressure oil pump?

 

Unplugged icp, truck will not run. No oil pressure on cranking. Please advise

 

Probably not the pump but standpipes and dummy plugs.
An air test would be in order to pinpoint and rule out the pump or other things but again more then likely it's the standpipes and dummy plugs as the pump on the 06 rarely goes bad unlike on early ones which arent as robust. Also would be a good idea to pull the ipr and check the screen. They can get damaged and cause no start.

How did you verify that you have no oil pressure?

You need an OBD monitor to help diagnose it. A code reader is not enough. If you're in a hurry, Scangauge II can be bought online and received same day for about $115+ tax at Advance Auto. If no hurry and you have an Android device, the Torque Pro app is the cheapest option. ($30...order Bluetooth adapter online for $25 and app for $5)

If you want to throw parts at it, go ahead. If not, GET SOME GAUGES to read live data, as stated before. We would like to help, but we need data.

I think you're saying you have no low pressure oil pressure from the dash gauge? Please confirm.

If not, pull the oil filter cover, use a clean screwdriver to hold the black drain back valve down, and turn the engine over with the starter wire on the passenger fender with the key off. Do not turn it over with the key ( it could start). If the oil filter reservoir does not fill with oil, you have a low pressure oil pump problem or low pressure oil pressure regulator problem.

 

Confirm. No low pressure oil pressure from the dash gauge. What gauges do I need exactly.

 

These ones. Use TRT30 at Advanced on line and pick it up in store.
