It won't start. I do not have a chip. I am just using a Superchips tuner to read codes. I don't know about the PCM. I do not know how to test it. I have a friend who keeps saying he will come over with his scanner. No show as of yet. I'm going to call in a little while and remind him. I can understand the IPR O-ring set up. I pulled the sensor off the IPR and got the number off it. I went to the International dealership and they pulled the part out for me. It is the one with the hole in the end of it. I didn't pull out the IPR. Just the sensor off of it. Could my oil be dirty enough to keep the truck from starting? It looks alot cleaner than any oil I've ever had in a diesel engine before. You can definitely see through it.
Batteries are fully charged.
There is a wait to start light for 2-3 seconds and the relay buzzes on and off for 20-30 seconds at a time. It is also 80 degrees outside.

Ryan, just so you know, I tried to start it with the ICP unhooked, too like you suggested. Threw a code and did not start. Code was for ICP circuit out of range.
On and off it still throws codes for ICP and CPS. Right now if I crank it for 30 seconds til CEL light comes on it will sometimes have 0344, 1280, 0603. It does not even make pretend it wants to start. No smoke, nothing.

 

if it is throwing a code after cranking and icp is plugged in and the code is for icp you have a problem.

this is what i would do:

change oil
make sure hpop is full
make sure fuel bowl is full
check fuse 22
make sure you reconnected ipr wiring
make sure you connected cps wiring
is tach moving while cranking?

i would have a vehicle on standby for jump starting.
do you see white smoke while cranking?
can you plug in block heater before this attempt for a while?
is the voltage meter dropping a lot when key is turned on. (like going from 12 to 9) or is the movement little like maybe to 11?

could be just a bad gpr. try plugging in the block heater. i wish i was still down there buddy sorry ive got a ton of spare parts and software to scan that we could of tried.

 

I do have a problem as stated in your first sentence. All that is true. I shall do all that you said. Tach is moving while cranking(at 200-300). I have completely topped off the batteries and have a good 3g alternator on my 88 351 F350. No white smoke while cranking. I guess I could plug in the block heater but it is 84 degrees out today. The voltage meter drops down to like 8-9 while the glowplugs are firing off and the GPR is buzzing, too. I wish you were still down here, too and I appreciate you feeling that way because I know you do not like it down here.

 

what do you mean gpr is buzzing?((((could this possibly be the idm making some noise???))))) or do you mean the click it does right when key is turned on and then the click 70 seconds later or however long it is when they deactivate?

do you know anyone with a psd? can you get them to come over and try there idm in your truck? and possibly the pcm? i would try idm first and try to start.

?????????MY FIRST SENTENCE!!!!
did you replace the ipr already?
can you pull a little brass plug from each rail and verify oil in each oil rail. (I AM TALKING THE SMALL ONES HERE...SIMILAR TO WHERE THE ICP SENSOR SCREWS INTO. ONE OF THOSE LITTLE HOLES..4 ON EACH SIDE.)??????????


things i am thinking could be wrong:

1.truck not hot enough in cylinder to fire the diesel. plug in block heater.

2. ipr

3. idm

4. pcm

5. cps (i know you said you replaced it. did you get it seated in the hole all the way?)

6. you have an injector that is stuck causing you to not be able to build hpo in the rail.

off to read about this whole adventure from the beginning.

is there any oil on the dipstick? how full or low is it?

 

any update on this beast?

 

Thanks for asking, Ryan.
I did not get to come up and see you because I am still dead on road 96 PSD. Been using the gasser for work. It's still going. Like the Eveready bunny.
Okay- Here's where I am. I did lots of stuff to the truck. I have lots of back-up parts. CPS, ICP, fuel pump(new one on), FPR cleaned screen and BB mod., fuel filter and oil and filter change, and quite clean engine top and valley. After doing all that and following several threads for the last two weeks, I think my problem is either IPR(o-ring or total unit), or HPOP. I am going to pull the IPR in a couple of days and see what I find. I bought a new one and I have it in my hand. I am thinking I might just switch the solenoid and try. If that doesn't work, I will switch the whole unit. If that doesn't work then I am going to try to get the stuff together to deadhead my HPOP and check it out on a 3000# gauge.

After I get it running again I am going to pull the turbo, do a 2" body lift, jack up the engine and pull the oil pan. I am hoping this will give me enough room to pull the pan without pulling the engine. Then I can get my dipstick flange out of the bottom of the pan and put it back where it belongs and reattach the oil pan. While I am there I am adding a EGT sender and wire. Then I will put on my new Bullydog downpipe and 4" exhaust(which way does the muffler go? Spiral cuts inside the pipe catching the flow of the exhaust?) Then I am going to get together the pipe for a Kwikfilter mod and the plumbing for a boost gauge and I will be done. Then I just need to reprogram with my Superchips 1705 which I got for the DTC reading capabilities and I should be super-stoked and super-stroked!!!!! This has been very frustrating and expensive. All this has been going on while I am changing out the E4OD tranny on my 1990 IDI 4X4 because it fried a week before my PSD died. My wife went away without me so I could stay home and make some headway on the trucks and at work. Several thousand dollars of unforeseen expenses. We will be coming to Seattle this summer or fall. Like to see you there. I will post back as soon as I try the new solenoid.

 

sweet man sounds good.

everything your gonna try sounds good.

i would think spiral cuts catching the exhaust would be the louder way. what ever you prefer i guess.

 

It finally turned out to be the IPR. I dead-headed the pump and it had no pressure at all. Zero. I pulled the IPR and put the new one in, filled the HPOP reservoir and it started right up. I'm gonna fully charge the batteries and take her for a spin tonight after work.

Now I'm waiting for the 2" body lift to arrive and soon I will do all the other stuff and have one nice truck with plenty of get up and go.

 

awesome man you got your baby going i am glad for you.

 

i have a 97 psd and it did the same thing and it was the icp.
