So it turned out to be the fuel pump after all. I put the new one in a week ago and it's been running ever since.
I also changed the fuel filter and the Fuel Tank Pressure sensor, since I snapped the old one in half trying to transfer it to the new pump. It was totally my fault, not gonna lie.
I got it running Thursday 4/24 since I had to wait for the new FTP sensor to get here from Rock Auto. I treated the new sensor like it was a priceless Faberge egg lol, and I had a hell of a time getting it seated into the new fuel pump. After about an hour of trying to push down and turn at the same time with no luck I did what any man would do when something doesn't want to go in...I spit on it, a lot. It went right in after that.
I was nervous the whole time, it was my first time after all ( First FTP sensor, umm, insertion

). The OEM sensor through the Ford Dealer next door was $130, the aftermarket sensor (SMP) was $61.25 so it was RA for the win. Even at $61 I didn't want to buy it twice lol.
It also took quite awhile to get the FTP connector to disengage from the old sensor since it was caked with dirt and debris that turned into a kind of cement. But my trusty old Craftsman pocket screwdriver made short work of it after I realized the issue.
It was a good feeling to finally get that connector to pop loose, but not near as good as that new FTP sensor finally seating into the pump.
I took some pics to send to my daughter so I reckon I could post them here-
Note- I'm pointing at the FTP sensor connector in the one pic to show her what it is and what was stuck in place when I was trying to get it loose. I've been trying to spark an interest in her about mechanics and how things work since she was little although I haven't gotten much of a spark at all. But I'll keep trying.
And the pictures are in no particular order.
The oddball pic of the hole in the frame is a cautionary tale for anyone who has an old Ranger. That hole opened up while I was beating out the 3 factory rivets to replace the rear shock mounts.
Ford engineers designed the rear shock mount like a cup, or vase if you will. Over time it fills up with dirt, rust, other debris, and moisture and if not cleaned out will slowly eat through the frame in the perfect shape of the mount. I had no idea, until this hole opened up right before my eyes. The frame seemed fine right up to the point I was hammering on the one rivet and was visually checked by both me and the two mechanics I take it to for inspection multiple times prior, we never saw anything that looked like it was getting thin or rusting through.
The mounts themselves can and do rust out and break over time, mine did on the driver side, which is why I had to remove the rivets in the first place.
I changed both sides but the drinker side frame was okay, and the mount popped right off the frame after the second hit on one rivet. I learned some things from the driver side which made the other mount a lot easier to remove.
So anyway- check your frames and rear shock mounts once in awhile lest you end up with a frame hole like mine.
I have more pictures of the shock mount job, as well as the leaf spring and 4 wheel brake replacement if anyone is interested. Just let me know.
