UPDATE - The van is running, but I still want to be sure I understand what happened:
Last night I picked up sone Diesel 911 and dumped it in the tank. I did not pull the filter because it was getting late and almost time to do the family Christmas stuff, and since the van is a half hour project to get to the filter, called in for the night.
Today I tried the hose on the drain test and it was definitely not 55psi coming out of the line, but it was a continuous stream. Just for kicks, I tested the fuel pump fuse and it was good, and swapped the fuel pump relay, which was also good. I cycled the key a few times to re-fill the fuel bowl, and tried starting it. It fired a few times and almost ran, then went back to just cranking. I drained the bowl again, cycled the pump, drained the bowl, cycled the pump, and cranked. Fired a few times, almost ran (longer this time) and died. Drained, cycled, drained, cycled...etc, cranked and Merry Christmas, she started. Ran rough and was smoking like a fiend, but running. I let it idle a bit, it slowly improved. Revved it up a few times, fumigated the neighbors, actually the whole block, and it continued to improve. So, I unplugged, closed up the hood and made a smoked lap around the block. Power was very low, but it continued to improve. Couple more times around and it seemed to be getting close to normal, so I ran it out on the main roads for a few miles. Everything seems good now. I stopped and filled up the tank and put more additive in. I plan to put a new fuel filter in tomorrow when the stores are open.
Now, I want to understand what happened before making the 450 mile run back home.
To summarize: Driving down I75 with the cruise at 70mph, van starts to stumble and loose power. Feels like running out of fuel. Low fuel light had come on approximately 5 miles prior (normally means 5 gallons left.) I make an immediate exit and get about 1/2 mile from the highway and it continues to peter-out and die. Will not re-start. Walk to the gas-station - no diesel (grrr!). Call dad who brings a couple gallons of diesel out. Cycle the pump a few times, van will not re-start. Some white smoke, seemed to fire erratically, but no re-start. Decide to call for a tow just as the police arrive and say we have to have it towed. Towed 20 miles to parents house..ok, at least we made it. Van sits over night. Thursday morning I jump on powerstroke.org (awesome site!), and all indications point to CMP, which had been replaced 5k ago under recall. Pick up two new ones from the international dealer, swap one in, no luck. Does not seem to fire, so I try the second one (who knows, right?) Crank and seems to fire, but no start. Back on powerstroke.org, lots of ideas to try. Put the battery charger on it to make sure voltage was good. Check the fuses - good. Maybe gelled fuel in pick-up? Put 8 gallons of diesel in so the secondary pickup will be submerged. Still nothing. Plugged it in to try and warm things up. Gave up and went to a family Christmas party. From here you can jump to "today" above.
Any theories on what happened? It has a new CMP and lots of Diesel 911 in the tank at this point. I'm going to try putting the old CMP back in when I get back home to confirm if it was good or bad. Meeting up with bigcountrysg tomorrow to scan it and see if anything else is up.
