eed help solving problem 02 -7.3. Truck has. Been running rough lie a gas motert hitting n 6 cylinders. After while it'll smooth itself out. Now wont. Start and got two codes. Po2211 and po670 I believe that's the icp.,, is there something else that I need to check

 

P1211{2}
ICP Pressure Is Above/Below Desired, Faulty IPR Valve

P1211{1}{3}
ICP Pressure Uncontrollable, Pressure Above/Below Desired

P1670 is a IDM code.

Is the WTS (wait to start) light going on/off like normal? How long is it on for?

To test the ICP, unplug it checking the plug and wires for oil. Start the truck, if it runs better or there's oil it needs to be replaced.

It also could be the UVCH, but definitely check the ICP first. What did you use to pull codes?

 

 

Sorry that code was. P1670 got codes from super. Chïp programer the truck died on mÿ wife's la's
Week it will not start it doesn't even fire off?

 

In that case, it's an IDM code, pushing it more towards the UVCH.

Does the WTS light come on/off like normal? Get any smoke when trying to start?

Checked all your fuses?

 

Wts OK. fuels all good.unplug orchestra no start
no smoke, bingo must be no fuel. I check this at
The start. pump was working there was fuel at top.
All OK, not now took off return line all I get is bubbles
Took off subply line same thing I have no pressure. Im
Lacking fuel!

 

If you open the drain(Yellow lever) on the rear of the bowl and cycle the key do you get anything?

 

Yes I get fuel

 

Where does the oil level need to be in the HPOP for it to start

 

1/2-3/4in below the plug.

You check the #30 fuse?
