When I turn the key to the run position, I can hear the fuel pump running. If the engine is already warm, then the fuel pump runs for just a couple seconds and I am able to start the engine and it runs without any problems. But, first thing in the morning, the engine won't start right away. The fuel pump keeps running for 4 to 5 minutes. The engine won't start until after those 5 minutes and the pump has stopped running. Once I get the engine running, there are no problems and it runs good all day. I can stop and start many times. I saw the following threads Fuel pump runs constantly - Ford Truck Enthusiasts Forums (ford-trucks.com) 97 F 350, 351 Fuel pump/pumps keep running. No start. - Ford Truck Enthusiasts Forums (ford-trucks.com)
Is my solution the same? Is it the PCM(computer) that is causing my problem? Or is it something else? My local mechanic replaced the fuel pressure regulator. It didn't help at all.
I am not as capable as that guy. I won't attempt to replace the capacitors. I am amazed that the truck was still running with all that circuit board damage. Also amazing is that when my truck was scanned, no error codes were emitted that described my computer problem. Here is a photo. The capacitor that I pushed over only had one lead still attached.
Now, I will try to find the proper replacement. I inputted my details into napaonline.com and they listed several items. I just have to figure out which one to order. The price is about $225.

Cardone makes reman replacements and also have new ones available in some cases.
I found a brand new one for van on Ebay for 275.
Mine was missing and just about died several times and was scary to drive around
Now runs great, I am able to solder the new caps in but went with the new one
Good luck
