Default 92 5.8l not starting after tank change

1992 f150 5.8l. I replaced the rear fuel tank on this truck about a month ago and It died shortly there after and it won't start at all now. I replaced the fuel filter today hoping it may have gotton plugged but it didn't help. Once I got it all back together I drove up to the gas station and filled the tank and drove home. I let it run for a while and then took it for another drive and it had no power whatsoever. I shut it off and it hasn't started since. I did have pressure at the fuel rail when I replaced the filter today FWIW.

I tried to access the trouble codes(check engine light is on) using KOEO but I am getting no codes out....the check engine light doesn't blink.

Any help would be greatly appreciated. This is my plow truck and the snow is starting to get deep

good question. I have no way to measure it but it did spray out pretty good when I relieved the pressure prior to the filter change. Any thoughts on how I can test that?

with a guage

just because it sprays out isn't a great indicator

HF has a guage lit for like $10, or maybe borrow one from autozone

I checked the fuel pressure and I am rock steady at 45psi which is what thge top end of the acceptable range is. I checked the coil and was at 1.0 ohms for primary and 7500 ohms for secondary resistance. The secondary is a little low supposed to be a little higher. I cleaned and inspected the cap and rotor(only about 2000 miles on these). Still no go.

Anyone have any other thoughts? I still can't get the trouble codes out either. strange

Did you disconnect the battery? If you did, a code might not come up right away. Exactly how is it acting? Sputtering like running out of gas? Like ignition is cutting out? Like someone just choked the engine? Still do it on the front tank?
