Possible failing fuel pump.

About 2 weeks ago I backed the car out of the garage to wash it and an hour or so later was going to put it back in the garage but the car would not fire but just crank over. I tried about 3 times to get it to start back to back with no luck and then waited about 5 minutes before trying again where it fired instantly and ran as normal. I drove the car the next day without issue and parked it until this past week when again it would not start after two extended tries. I went about my day and tried it again that same evening and it started as normal. The first time I just chalked it up to being a fluke and thought maybe something got wet but I have washed the car hundreds of times the same way without issue. Yesterday I started the car to get some gas and it seemed to do the same thing again before again running as normal. When I tried to fill up the car within 2-3 seconds of trying to fill the tank it came gushing out like a geyser covering me and the front of the car. I tried it a second time and it did it again though it might have been possible to slowly fill the tank but I did not try as something was certainly wrong. I have spent time searching here and through google on general and some of the possible no start issues would be a fuel pump that may be dying, fuel pump relay, or Crank position sensor. The problem I have had so far is the problem seems to fix itself before I have time to diagnose the issue with a fuel pressure gauge, etc. Does a failing fuel pump just suddenly die or is it possibly a progressive thing? Could the issue with the fuel filler be related? The timing seems very coincidental?

What year is your car? Does the tach move when cranking?

2000 model... I have not had the foresight to look at the tach when it has happened to rule out the CPS until just recently.

I had a bad CPS. The car started when cold. When warmed up it would not start, but if left for about an hour it would start and run until the next time it was turned off.

I forgot to mention that I do have a durametric but not sure that I could easily find the problem with it either.

Due to the fueling issue, I'd look at the threads that come up in this search:
https://duckduckgo.com/?q=site%3A986forum.com+regeneration+valve+&t=fpas&ia=web

"Regeneration Valve"

Or another part of the evap system.

Finally had some free time to look at the car and got the fuel tank

breather valve assembly unbolted as I was not getting the "click" that people described you should be getting with a functional unit. I was shopping around to purchase the valve and hopefully fix the problem when I noticed these wires that were damaged. Is the narrow cylinder the magnet that people have described that is part of the valve? I can't see exactly where it goes and I was very slow and methodical when taking the assembly off to hopefully not damage or lose it like people reported. The other wire is obviously broken in half and I suspect this is rodent damage based on some droppings I have seen in the garage lately. I do not see exactly where the other broken end is though?
