97 No Start, bad IPR or LPOP?
Hi everyone, I've been reading up on this forum and others for days but finally it's time to break down and ask for help.
My 97 PSD ran fine, now suddenly won't start, and I have no oil pressure - does this point to a bad LPOP, or could a bad IPR cause no oil pressure as well?
I picked up my second Powerstroke, a 97 F-350, two weeks ago. It ran great when I got it, I changed oil (Rotella 15w40), filter (Motorcraft), and fuel filter just to be safe, drove it to work a few times, and towed my Jeep with it last weekend. A couple days ago I started it up and it ran great, put it in gear and it moved about 2 feet and died on me. I started it again, it ran for about a second and then died again. It will crank just fine but won't start.
Of course there has to be an easy explanation for why it would work fine one day and just quit, so I looked up all of the possible reasons I could find, and here's what I've found so far.
- I have no present or stored engine codes, although I believe I have cranked the engine sufficiently to produce IPR/ICP-related codes (10-15 seconds of cranking). This is with a simple scanner, I do not have data streaming capability.
- There's no smoke coming out of the exhaust. No sputtering or hints of firing at all.
- I pulled the fuel filter and the bowl is full of clean fuel.
- I checked the engine oil, it's right at the full mark (and still clean, less than 100 miles since the oil change).
- Checked the glow plug relay (although it's 70-80* here) and I have good voltage on both sides of it with the key on.
- The WTS light does illuminate, and then goes out as expected. Fuse #22 is good, which controls the fuel bowl heater and I read is prone to going out.
- I've checked all of the other fuses as well, some only have power with key on but all of the fuses themselves are good (voltage on both sides of the fuse).
- When cranking, the tachometer reads 200-300 RPM, which I believe indicates the CPS is good.
- I pulled the ICP harness connector on the driver's side fuel rail, so that the computer would use the default IPR map, and that didn't help.
- If I fill the HPOP reservoir, I can get the engine to run for 5-10 seconds before dying; after that it will crank without firing, until I add more oil to the HPOP.
My suspicion is that the LPOP has taken a dive and needs to be replaced (which sounds like a driveway job), or worse, the oil pickup is cracked or damaged and the motor or pan need to be pulled (sounds like a pay-someone job).
I am aware that a faulty IPR would cause the no-start condition. However, even with a bad IPR would I see oil pressure due to the other restrictions in the lube system, such as passages to bearings, lifters/tappets, pushrods, etc.? It seems like an IPR is more likely based on other owners' experiences, but I'm not sure if no oil pressure can be caused by a bad IPR.
Thanks for reading and for any advice anyone can give me; I tried to figure it out by keeping quiet and using the search box, but I just need to know where to go from here.
