Help please, no start after o-ring replace

[Brickhouse]

Longer story short. Blew an HPOP line O-Ring. Had to replace with cheap to get home. Sprayed degreaser and pressure washed off oil mess (7qts). Went home (400 miles) Ordered up good O-Rings (+) spares.

Driven and towed untill new rings arived. Alls seemed fine.

Today: Sprayed degreaser and washed off leftover oil mess with reg hose. Carefully removed both lines from hpop. Removed O-Rings, and cleaned.

Put new correct rings on, reinstalled.

Started it up. Small hickup getting oil though, seemed like going fine, then hard shut down.

Even with being very carefull and as clean as possible, there is one note I think happend. The hpop was powerdercoated, I did notice slight flaking where lines go in.

Full good, dumped drain, can hear full at start. No tach movment, no SES, do see oil gauge drop and clime. fuel Inject pulse width .60ms, All looks good there.


Hooked up AE.

ICP volts: at rest 21, 3 sec 36, stays 36/37

ICP PSI: 105.71, 3+ 108.12 , 5+ 104.10

ICP duty cycles: at rest 14.84, 3 sec - 44.14, 5+ - 64.84


I'm guessing here, small debree got into IPR? If so, what do I do? I'm still new and learning. Please help, work Monday.

I'm still to new, and found nothing in the search of CPS. What item is it? How do it check it? Where is it, what's it look like?

CPS= Cam Position Sensor, this little beauty has been the culprit for no starts for many years, Ford has a recall on them and you can check with your local dealer to see if they can do the recall without the truck coming into their shop.

O`ya, CPS. My mind is shot at this time. It's been replaced at Ford twice.

checked reservoir level. Good. Plus have the add on res setup.

Still can't figure out what went wrong with the o-ring install. Not that hard to do....

I think I located the problem. The IPR sensor nut fell offfffffff…….. If the nut washed down the back of the valley, I’m going to have to remove the small front trans cover? To dark to work, and back is out. Will get it back together in the morning and report back.

Just to be safe, can I just push back in, and put nut back on? Whan and if I find the nut....

I had mine fall off once and it was just hanging out in the valley. Just slide the sensor into place and thread the nut back on, I'm not 100% sure that is the issue with the no-start, when came off it mine didn't effect it but if your sensor came off it could possibly cause the problem, good luck!

I couldn’t wait, found nut, back on. Wasn't the problem. Still stumpped

Try going to Napa in the morning and get a CPS, after that I would look at cleaning the IPR, there are some good write ups online with the proper procedures, just google "ipr cleaning"
