They seem to have forgotten I told them I was broke down on the side of the road).
I'm not completely up on motors with computers in them but am puzzled by the fact that my glowplug light would tell me if my truck would start or not. If it stayed on then no start. If it went off it would start like nothing ever happened. Still no ses light on the dash. I don't think it's glow plug related but don't know how that relay could tell the truck was broke. Also the bump may or may not have caused the engine die since I hit the bump around the same time the truck died once, and there were no bumps the next time. I did hit plenty of bumps the last 70 or 80 miles with no issues at all. Sitting with the truck off and the hood open seems to have helped, but the last time I only sat 10 minutes, not enough time for the engine to cool down.
Any suggestions on advice to give the mechanic would be appreciated.
One last theory. Big brother (Ford) marketing plan. I got a brochure in the mail Saturday telling me how wonderful the new ford trucks were. I had another mailer from Ford when I got home today, and I've seen about 10 ford commercials in the last hour. Maybe it's sabotage. (Update:11 commercials now)

There are two little boxes next to the big fuse box under the hood next to the master cylinder. I think these are the relays the guys in the post I linked to are talking about.
Oh and LOL at your last theory.

I've had the cps start to act up before and this feels different. The shudder is the exact same as the bad fuel pump shudder. The old fuel pump was definitely broken. I'm starting to wonder if my gremlin caused the fuel pump failure. Besides last time I had CPS issues the ses light stayed on. I have no lights on the dash when the truck is running.
I can only hope that I'm wrong and it's only a $20 part that's broke.

We've had folks before get a small rock stuck in the inbound fuel hose (fuel going from the tank to the pump) and clog it up, cutting off the fuel flow. If that happened to yours, could've burned up your first pump, and still be cutting off flow to this one.
Just one more idea to toss out there... Really hope you get this one figured out!

Anyone have any ideas on how that glow plug light factors into all of this? If it stayed on the truck would crank but not start. If it went off it would fire right up. There's got to be a sensor or computer relay somewhere that is seeing what the problem is.

I have a utility bed truck, so I am not sure if regular pick up tanks are the same. Here is a pic of my truck. I just bought the truck in March so I don't know how long it was building up. The truck has 188,000 miles on it now though. I did not have to jack up my truck to get the tank out. Lots of room. i could actually sit up and remove the forward tank bolts. It was easy to do, just time consuming. It took me 4 hours the first time. the second time it only took 1 hour, maybe less.

BTW, while your pump may have died. I am beginning to suspect a UVC harness issue with your GP light and SES thing. You may want to look in there. You might also just slap the old CPS in there just to see if it works. I hate electrical gremlins.

Partial update
Mechanic said he could not duplicate the problem. The only code he found was a bad battery connection. He's going to drive it some more and see if he can duplicate it. I'm kinda hoping it breaks down and leaves him stranded so he makes sure to fix it, but I'm afraid my gremlins have decided to behave for the mechanic.
