Will do, thanks

 

Replace your FICM power relay. I just had the exact same thing happen to me. May or may not start. Hot or cold. I thought it was the PATS antenna ring around the key. Finally sent FICM to Ed Stefan he said it was good. Got it back, changed the relay and life is good. My X had 122K on it.

Thanks for the replies - they put me on the right track, just got to confirm next time it happens.

I'm using Forscan and the pressure is given in kPa, so when I saw ICP of 700 last week I assumed psi, but 700kPa = 100psi. Like I say I'm 99% sure but I need to get it warm and provoke the no-start to be sure.

Looks like air-test when hot, or any other ideas? This may take a while as I ordered the IPR tool and picked up an empty parcel this morning, just what I don't need now...

 

yep your close-- 700kpa is 101.5264 psi

 

dude whats your icp voltage?!? Its simple and easy to check. everything works together. everyone forgets to check the voltage on this little sensor while trying to trouble shoot a no start. It could be in spec.. just check. .25v key on engine off

 

on the nail, 0.25V, just checked. I'll check again next time it won't start.

Engine died on me 3 times today in 150 miles, each time I took my foot off the gas in traffic to brake - each time doing less than 30mph, but started again directly. I'm now being real careful - soon be left foot braking...

 

Kick this thread alive again and let you all know how it went.

I'm working 200 miles away from home now, Monday to Friday, so the wife needs reliable transport and doesn't want to see half of me under the hood all weekend. Something had to give so I found a German Ford dealer who repairs the base powerstrokes - talks the talk, and look like he walks the walk. Managed to get there under own power, but as soon as he took it out it stalled and he had to tow it back.

They diagnosed HPOP and possibly ICP valve, ordered and fitted them - took 2 weeks to come in from US - and it's just back from a 400 mile round trip towing a small trailer with furniture for the new apartment. Plenty of cold, warm and hot starts with no issues. Labour, including updating software and changing the EBP was 7 hours.

The old ICP screen has small metal particles and is slightly damaged. Did an oil and filter change that evening and there was no sign of metal on the sump magnet - nothing at all.

Workshop chief also said I was wrong to use 5W-40 (Mobil TDT) and should only use 15W-40 - the TDT is too thin he says. Showed him the Motorcraft document that says its OK for all the powerstroke engines but he wasn't having any of it.

Any thoughts/views/ideas on any of this? Be very interested to hear them...

 

Possibly IPR valve??? YES or NO?! I don't know how cold it is where youre at but I don't use anything but 5weight Rotella. Injectors like thin. By ICP valve you mean IPR.. ICP sensor monitors IPR valve. If that screen was messed up I would recommend checking the screen under the oil cooler. Im mad he didn't mention that..

 

Brain fade after a long week - IPR it is, good spot
