Died while towing and other issues!

[turd7.3]

I searched in the forum but didn't find my specific problem.
While towing my 5th wheel, my 02' f250 engine shut down. The engine will crank but will not fire. I thought it might be my CPS, so I swapped it out with a gray one I had in my glove box. My truck was into the ford dealership 2 wks before for the CPS recall.
Now when i turn the key to the start position, it sounds like 3 of the relays under the dash are rapidly clicking. My batteries are charged.
I have an edge evolution tuner. When the truck died it tried to go back to stock mode, but stopped doing anything at about 70% download.
I'm worried I will have to get my computer reflashed.
Are the relays on the fuse panel "special Ford" relays or can they be replaced with Napa parts?
Thanks ahead of time.

im having the same problem, any ideas. my doorlocks even start locking and unlocking when i cycle the key. after about 12 times of cycling it fires up. sometimes it will die then i have to go through the same process.any help would be greatly apreciated.

is there any oil in the oil pan?

[$RONNY$]

yeah, that was the first thing i checked. i have good oil pressure, and fuel pressure. i changed the cps also. the problem didnt start till i did the diy intake. dont know if its related or just happend around the same time.

found out the problem, the previous owner didnt seal off the pcm when he put the chip in. a bunch of dirt got in there. cleaned it with electrical contact cleaner, put some dielectric grease and sealed it with a/c tape. runs like a champ now. stupid easy fix

So I posted a while back, that while towing my 02' 7.3 just shut off.
I thought it was the cps, swapped it out on the freeway and nothing.
After 3 flatbed tows in 4 days, it turns out it was a short in the speed control sensor recall harness that was installed 2 weeks earlier. Runs fine now and my cruise control works agian. Damn stealership!!!

I hope they covered the costs incurred cause that should be on their dime IMO.

Having missing problems lack of power and response issue put a load to her and she does not like it or just refuses to pull. dealership say there computer said change IDM and then we will go from there That is a 1300.00 start. Said the hell with it and had it towed home,got IDM change seemed ok unitl I started to load it and pushed my EDGE to 5 and I can feel the problem coming back. I had that damn speed sensor recall done or should I call it a tape job. I am goging to reverse that and move from there. Kinda of at loss so will try anything at this point. You guys got anything else you mite know of would be much obliged. Thanks

Check the connections for the UVCs on both sides where they plug in right at the the valve cover. They get chitty and cracked and cause all sort of miss/loss of power issues. Just an idea. For some reason seems to the driver's side more that the passenger side

Going through all connections now clean and spray the problem just sort of popped up see what happens
