Where does this plug into? Is it related to my no start situation?

Background information. I purchased the truck about a month ago. For some reason it takes about 6 seconds or so to start at all times whether cold or hot. First start up it runs a little rough (not bad but just a little). The only mods are 4" turbo back exhaust, EGR delete and that's it. Last week I left out and felt the truck running a little rough, turned around and went home and it died in the driveway. It spins over, doesn't start oil pressure gauge doesn't move at all while the motor is spinning. Has fuel in the fuel bowl. Good FICM volts. Had an Edge Juice when I purchased it however I removed it since it did nothing for the truck. The truck is a 2005 with 75,600 miles.

First question, what does this plug into?


Scangauge II view while cranking:

Battery volts are a little low (11.9v) from diagnosing and turning the truck over. However it isn't the issue, they are new Motorcraft batteries.

Looks like your mass air flow plug..... Your going to want that plugged in. Should be on intake tube

Yep that's the maf connector, I don't think it will cause a no start but anything is possible.

Lol I swear I looked everywhere for the plug except the MAF. It even looks like a MAF connector now that I look at it again.

The no start could be a high pressure oil leak.Hpop or injector o-rings

No MAF on this truck. If I remember correctly the MAF on this truck is just inserted in the intake tube.

My 2005 has the same plug, not plugged and no Maf. I think it's actually an Air intake temp sensor. From what I gather these have different strategies that rely on other sensors like ebp and others to make fuel decisions. From your first scanguage pic your ipr is open wide and its still not reading icp enough to crank. You can try unplugging the icp sensor to see if its failed but if not you have a major hpo leak.

ICP when cranking needs to be over 500psi. Looks like the IPR is trying to open, but isn't giving the ICP enough oil psi to reach 500psi.

Are you running aftermarket oil filters?

No, factory oil filter. Tried unplugging the ICP and still no start, just threw the P2285 code.

I guess I'm looking for a leak at the HPOP.
