Alright I'll try to keep this simple
-92 teg body, converted auto to manual
-started and drove succesfully after conversion
-had to replace my leaking fuel tank
-had to cut out metal lines and replaced with rubber (had to do it on my 91 and it worked no problems)
-went for a 60 mile cruise!
-2 days later my water pump started leaking...figures oh well timing belt and water pump. Done it before, no biggie.
-only had 2-3 gallons in the tank maybe a little more.
-ran to operating temp, shut down
-connected jumper wire for ign timing, connected timing light (warning with timing light says DO NOT CONNECT WITH ENGINE RUNNING!)
-Tried to restart and no fire...WTH?
-turned key, no fuel pump...well sh**- at this time I was not aware that a solid CEL meant the ECU was failing. The car sat in the rain for a day and half prior to pump replacement.
-double checked the timing belt.
-eventually got another ecu, replaced my relay while I was at it and took care of the fuel filter, which I still believe is hooked up backwards!
-started and ran to operating temp.
-pulled out of the driveway and had a hiccup...weird
-got only a little way down the road, and the car died maybe a mile down the road. Restared once but didnt get far.
-got it home, TRIPLE checked the timing belt.
-ive tested my distributor, its in range. I replaced the spark plugs, wires, even bought a new dizzy (yeah a cheap crappy new one-also tested fine)
-the car will start with starting fluid...the first time it ran smooth for almost a minute before it slowly misfired and died.
-it restarted for about 10 seconds with no additional fluid
-other attempts to restart with fluid have been more rough...assuming it's just because its starting fluid and probably not so good for the plugs.

Personally I think the aftermarket fuel pump is crappy, or a have a bad wire and I'll beat my head in if I have to chase down something like that. I'm considering switching the lines on the fuel filter.

I've already purchased another pump, that is the oem bracket with wiring, before, I just did the pump. I've also ordered another ecu, because for all I know the other one I have is just crap also. The original ecu is confirmed bad with a solid CEL.

Not sure you can hook up a fuel filter backwards.

Have you re checked the rubber hoses you used where you cut the metal line?

Sounds like fuel is not being deliver d from it starting with starter fluid only.

And you don't hear the pump prime anymore?
Is the harness plugged into the pump all the way?
Have you Checked any fuses? Maybe one is loose and hardly making contact?
Never heard of solid cel meaning bad ecu.

Have you tried manually jumping the fuel pump to see if it pumps fuel?

The fuel filter can absolutely be put on backwards. Both holes the same size. I'm pretty sure it's wrong. Even the pic in the book is opposite. Arrows were opposite on new filter but on other side of the holes. Pump primes every time. Solid CEL without jumper but pump will turn on after literally a minute and light goes out, bad ECU.

Yeah hey thanks. I've done it before. I was just going by the arrows on the filter... The oem filter had them in the front, the new filter had them in the back. The arrows were reversed on the new filter. I assume I have it wrong, as I have said. Others have ran into this problem as well. Either way, yes it was a stupid oversight, can't replace it now because it's too damn cold, and I'm not playing with fuel in my tiny garage. Going to wait for it to warm up so I can open the door. Have a friend who was burned head to toe. I don't take chances anymore.

Either way....I had fuel to the rail because when I tested for leaks, I had a leak at the rail. Other than that after I got the other ECU the car fired up, and died down the road. I think either the injectors are clogged...seems un-likely, or the aftermarket ECU is junk-possible, or the aftermarket fuel pump isn't working properly- honestly when I was installing it, I was unhappy about the way it used a clip instead of screw on style like the old one was. Personally I think its the pump even though it's priming.

I've checked fuses and wiring over and over and over and over and over...checked all my grounds before I did anything else, I even added fresh wire, sanded painted the whole 9 yards. The car has started ran and drove. Other than that possibly something with the pressure regulator, but I will check that later, again when its warmer.

Try jumping the ecu for codes. A solid cel just means you have a stored code.

I was not posting the video to show you how to do it. At this point I'm aware you know how to replace it. I showed you the video because they guy mentions where the hoses go.
Idk what arrows youre talking about. But basically the U-Tabs do not go on the firewall wall side. The U-Tabs are on the engine side. Not sure if you knew that or not.
Just try swapping the hoses when you can.
And as mentioned check for codes.

Problem solved! It was the aftermarket fuel pump! Purchased an oem replacement, bracket, pump, wiring assembly (130$ vs 30$ for just the pump). Car fired up like I was just driving it yesterday! I did switch the fuel filter lines before I replaced the pump. No difference. I also checked all my wiring, injector resistance, and ignition switch (which was loose!) So my original problem was the ECU failure. My secondary problem was the pump. I know it primed, I had fuel at the rail. Not sure why it just wouldn't work though. It was rated properly for fuel flow, but didn't sit in the oem bracket correctly.
