Yeah, we don't know for sure, but if I had to guess, it's probably the original fuel pump and filter sock. The truck has just over 200k miles on it.

Considering how old it is, it still purrs like a really big cat, but the other day it crapped out on us and simply refused to start. I verified the fuel pump was working and also verified good hot spark coming from the coil pack, but still it refused to start anymore.

Puzzled I was, so we called a friend, and he was a bit puzzled too, but that's when he suggested taking a hammer to the bottom of the gas tank, to try to dislodge any crud. Well, we happen to have a sledgehammer, usually just used as a prop stick for the toolbox, but I smacked the bottom of the tank about 6 times (I didn't even smack it hard), and it started right up 👍

Another commenter suggested a rubber mallet, which I actually do have, and that'll be going into the truck toolbox later today. As far as replacing the pump/sock assembly, well I won't be able to do that myself out at our apartment, as it requires either dropping the tank or removing the truck bed first, so that'll have to be done at a shop someday whenever we have the extra money, whatever the fuck extra money is...
