Was runnied, died, now no start
2000 F-350, 214,000 miles, Manual Transmisson
Had Superchips 1705 Save Tow installed, other than that, bone stock.
The truck sat for about 6 months while I saved some money and went through the transmission. While it was down, I changed the oil and filter. I am a full-synthetic guy, and used Rotella T-6.
I got it back on the road and ran it about 80 - 100 miles, going to work, out to lunch, back home, etc. Everything was just fine. I filled it with fuel, drove it 18 miles home, and parked it overnight. It got down to low 30s overnight, I glowed it twice (as I usually do), and it started just fine. I let it warm up briefly while I scraped the windows, and headed out. It still wasn't up to normal operating temperature. About 1/2 mile down the road the engine started "nailing" (sounds like the injection was too advanced) and losing power. By the time I was able to pull off the road it was barely running and died. I got it restarted and headed back to the house, still barely running, until it died on the road and wouldn't restart.
I towed it home, and (first things first) replaced the cam position sensor. It had a gray one on it from the recall, and I put on a known good black one. No start, but I did have tach response (about 150 - 175 RPM) cranking. Next I replaced the fuel filter. It looked fine, but that was the logical next step for me. I topped off the filter bowl with fresh, clean diesel. Still no start. The fuel in the fuel bowl smelled and felt normal. There was no water in the water separator.
((BTW, the filter I removed had an o-ring in the indentation around the bottom of the filter, adjacent to the filter element. Not the seal around the shaft, but around the lower outer diameter of the element. The new WIX filter didn't include the o-ring. When I used the o-ring from the original filter, I couldn't get the new filter in. I removed the o-ring and installed the new filter. Is the o-ring required? I would have assumed that WIX would have included one, but none of the ones on the shelf (both WIX and other brands) included the o-ring. ))
I checked the #30 fuse thinking that the filter housing heater was shorted, but it was fine.
Anyway, at that point I broke out the Snap-On Solus scanner and read codes. I had only a P0603 (from flashing the computer with the 1705) and a P0605. A lot of posts indicate that the P0605 was not unusual when chips were added, but I didn't have any, just the SuperChips Safe Tow mode flashed. Ultimately, from what I read, I decided that the ECM must have crapped out. I bought a known good DPC-421 and installed it. The original equipment was an XC3F-AF. The replacement is an XC3F-KD. I installed the -KD, still no-start. Damn - wasted money. After the replacement I had just the P0603 code from the swap, which I cleared. From that point forward I haven't received any codes what so ever.
Next I checked the HPOP level. It had about 1 1/2 inch of oil in it. I filled it with fresh oil, but it would immediately drain back down to that level. I also checked the ICP for oil contamination, but it was clean. An attempt to start the truck with the ICP disconnected didn't fire. I broke out the Solus again and cleared the ICP code from attempting to start with the ICP disconnected. My HPOP is 2300 -2500 while cranking. An injector buzz test sounds fine.
The other readings are:the
V PWR - 12.6 KOEO, 10.7 cranking
ICP - 0 KOEO, 2300 - 2600 cranking
ICP V - .2 KOEO, 2.87 crankingthe
IPR - 15 KOEO, 60% or greater cranking
Fuel PW - 0 KOEO, 2 to 4 ms cranking
GPC 99% cranking
Again, there are no DTCs at all.
I pulled the fuel filter back out, and with the filter out, turned the ignition on for a few seconds, and repeated that a few times. The filter bowl is not filling with fuel, making me think that the on-frame fuel pump is bad. I've checked for power at the on-frame pump, and have it.
At this point I am leaning towards replacing the fuel pump, but wanted some feedback from the forum before I throw a couple of hundred dollars out the window.
So, thoughts anyone? Have I skipped a step in my troubleshooting?
Also, any thoughts on the fuel filter lower o-ring? I haven't searched for any posts about that, so excuse me if that has a thread already.
