No fuel
I'm sure it's been covered....and I'm sure I could spend weeks sifting through the mountains of info on the subject. Which is why I'm hoping yall will bear with me and have mercy....
2005 supercrew lariate with 5.4l 3v 245000ish miles
Replaced injectors-one was stuck so I replaced them all.
replaced coil packs and plugs-was in there anyways.
Truck ran great for about a month and then it decided to just randomly not start. Had P1000 P0190 P0191 P1233 B1318 showing.
Over the next couple days I checked fuses and relays they checked good. I replaced fuel filter, fuel pressure regulator, and fuel pump drivers module. Still no fuel. Bit the bullet and dropped the tank and replace the pump. Checked power and continuity to everything. There was power to fuse box, power to inertia switch, power to drivers module. But not out. Bypass the module and pump worked fine. So I got another and still nothing. Had a friend come over and put fresh eyes on it and as he was double checking my work he somehow managed to get it to run by simply pulling it all apart and putting it back together. Ran solid for about 60 miles then stalled and now I'm back at square one. Only code showing now is P0191. Thoughts?
