It's really stumped me, that's for damn sure. Otherwise I'd have it running by now. I would replace the fuel pump if I knew it was bad, but it's working and pumping gas... like I said though, I don't know how much pressure there is, but it will fire, as you can tell in the vid. I don't feel like spending 40 bucks on a pressure gauge to find out just this once. I've already put too much money into it already. I tried swapping the ECM with the one from my other Jeep as well just for the hell of it, but no difference there either.

I just put some gas I had in a can (It's only been in the can for two months) in there today... the little bit of gas that was still in the tank (the low fuel light was on) is probably 2 years to a year old. I put some HEET in there before I started working on it. Probably needs some Seafoam.

I should probably add that I've tried starting fluid, which doesn't seem to work that well either, (the cylinders fire more often, but still no start) so the problem is probably in the spark, but it does fire, so that means there's only an intermittent spark? What could cause that? Like I said earlier, I already replaced the CPS and replaced the wiring with the patch harness, so what else might cause an intermittent spark?

A bottle of HEET, it was the only thing I had lying around at the time and it was a fuel treatment, so I figured it would be better than nothing. Like I said, there wasn't much gas in there because the low fuel light was on. I poured about a gallon to a gallon and a half in today. I need to get some more gas but I didn't want to put much in if I had to replace the fuel pump.

id take the fuel line off at the regulator and attach a hose to it and crank it over try to get as much out before putting more fuel in

I had to share this, because in my search for how much fuel a 12oz bottle of HEET treats, I looked at Amazon.
Frequently bought together:
HEET gas line antifreeze and water remover
Synovex H Heifer Implants
Finaplix-H Cartridge
I was curious as to what the last two were, so I clicked on them. They're anabolic steroids for increased weight gain. Apparently, people who use HEET in their gas tank like to gain a lot of weight fast... A LOT of weight.
EDIT: Actually, after a little more digging, the last two are for weight gain in cows, to put it simply. So, a lot of farmers like to put HEET in their gas tank and put their heifers on the 'roids.
