Ran great, died while running, no start

[JaxDually]

I have an 05 F350 with 104K mi. It was running absolutely perfect then when turning at a traffic light in the rain, the rear wheels lost traction, I let off the accelerator, and the truck was dead. It was acting like the Batt. was dead so I had them checked, one was replaced, the other needed a charge. Still no start. I took it to the dealer and they said it was the hpop, the ficm, the gpcm and the ipr valve. I find it hard to believe that all 4 would simultaneously fail. Could this be possible?

The FICM I can believe, if there is supporting documentation as to the steps taken diagnose its demise. At 104,000 miles, I would be leary of the need to replace the entire HPOP. An STC fitting maybe, but the entire pump, I doubt it. This is unless the diagnosing tech found metal filings on the IPR valve screen (hence the quote for that part too). The GPCM I can understand, if there was any P06XX glow plug codes set. But I agree that it seems rather hard to believe all four would simultaneously fail. The batteries though, I always replace in pairs. THAT may have caused the FICM to break down.

I'm pretty sure all the dealer did was plug the truck into a scanner and read the codes. I've seen that there is a way to check FICM voltage and repair the FICM. I've been thinking of going that route for starters. I've read that there would be white smoke if it was only the GPCM, there was no smoke. Although since getting the truck back from the dealer I noticed that the WTS light now stays on longer than it ever has before. Why is it that the batteries need to be replaced in pairs?

I didn't replace both batteries in my truck after I got it, just the bad one and within 3 months of driving the other bat went bad. Not saying that this will happen to you, but if one is going down the other has seen the same life as the bad one. Also when I replaced mine I stepped up to the 850cc bat's instead of the 750's that came with the truck, so this was a step up also. When I shut my truck off and it wouldn't restart, there was a piece of the screen from the IPR that was stuck in the ipr valve pintel. I found that out when I dissasembled the IPR.
