Another no ICP thread

Hey guys, 2000 ford F550 387k miles. It needed some love, I had a no start issue with no ICP so I replaced the HPOP with a cnc fab stage 2 HPOP, then a melling LPOP and IPR from orielly. The LPOP fixed it. (Threw parts at it because I was going to replace it all anyways but the LPOP was the 3rd part I threw at it)

Then it ran but like crap...It had an injector going out. Previous owner had 5 reman injectors and 3 originals in there. I ordered 180/30 injectors from FFD, injector cups, new glow plugs, valve cover gaskets, and an Irate T4 turbo kit with the 364.5SXE turbo as this rig is going to be hauling heavy and in remote areas.

Anyways, got it all done and I go to start it and after 8-10 times of cranking I am showing zero ICP. Any suggestions?

Did you open the hpo bolt in the head...and crank until oil ran out. Drivers side first then passenger side?

I didn’t, I just pulled the ICP sensor and it was pressurized for sure. Thanks.

Is the hpop res full? After pulling all the injectors it usually takes several long cranks to get the system filled and pressured. Like 3-5 20 sec. cranks, does for me anyway.
Oh and in case this is your first time on injectors it will sound like crap at start up and most likely smoke a lot. totally normal just get in and drive.

I think I have a ton of air inside, I was reading 0 ICP for over 10 cranks of 20 sec. I pulled the ICP sensor and it started showing 2200 ICP, screwed ICP back in and then cranked and back to 0. Unscrewed it immediately after cranking and it was pressurized and blew off air.

Yep, thats me, it was at 0. Long term I will swap out out for a motorcraft. I got what they had in stock at the time. Info on ICP readings above.

I’ll double check it today but from memory it starts at 14.9 and goes up to 65% I wanna say.

I would change that icp to motorcraft first thing. You can also try cranking without the icp pigtail plugged in, the pcm will defer to default values.

Start by checking the oil in the reservoir. If it's low or even empty fill it up with good clean fresh oil and try cranking it again. If it's still won't start or register any pressure check the reservoir again. If it's not maintaining a proper level might be a low pressure pump issue. If it is then IPR is a suspect

I filled up the HPOP Resi, it only wants to make ICP when the ICP sensor is unscrewed from the oil rail. I didn't try ICP unplugged but screwed into the oil rail. If it is making ICP to about 2200 psi unscrewed wouldn't that sound like the IPR is working and just has a ton of air in it? Either way I will replace it with a MC one. LPOP is a new Melling one.

ICP is MC, IPR isnt, I will order one on Amazon since it is like half the price.

be careful, theres china rebranded motorcraft floating around on ebay and amazon. Best deal your gonna find is here(unless you have account at ford). https://www.riffraffdiesel.com/ipr-i...gulator-96-03/

Rockauto looks cheaper till you add shipping and tax

what platform are you using to read pids? would be good to check icp, ipr %, p/w and cranking rpm. Also be goo to do a buzz test. Did you verify old ipr was bad? Hate to waste $200 that you could put towards a brownie box or rear axle etc

When the ipr solenoid not working it still slowly moves oil thru. IPR coil should ohm out to 5-20 ohms.To your point about the icp showing 2200 with sensor out of hole. When the computer sees extremely low icp at cranking it defers to a value usually 2000-2000 range.

gotcha, makes sense. I did go check on the truck at lunch and noticed my HPOP resi is empty again. I just replaced the LPOP and that was the reason it wouldn’t start last time

im using a scan gauge for now.

I wonder if pickup in pan is partially clogged or something?

i cant recall how the lpop works as far as parts and pieces

id reccomend forcscan lite for phone and obdmx+ bluetooth dongle for diagnosis. You can run tests like injector buzz, data log etc

maybe someone else will chime in
