Message: [QUOTE="slowcoupe, post: 1303289, member: 5146"] Now it was time to fire up the truck. Turned the key over a few times and open the water drain on the rear of the housing. Bowl filled nicely. Fired right up. Checked all my fittings etc for leaks. Nothing! So I was excited to pull it out and take it for a test run. Truck ran for a whopping 5 minutes and died wouldn't restart. Things snowballed from here. I immediately assumed CPS sensor as I had one go out on an old 7.3 and it felt the same when it died and no restart. Used my dads scan gauge II on the truck and had all kinds of codes. P1282 Excessive ICP P0231 Fuel Pump Secondary P0344 CMP Sensor Circuit Intermittent and excessive run code. Don't remember exactly what that code was. Started by replacing my CPS with the upgraded style since signs pointed to that with the crank but no start. Fired up again and died. Pulled he fuel filter from the bowl and depressed the tabs. No fuel in the bowl now. Dead fuel pump.... I went with an OEM fuel pump. Fired right up after replacing the pump and would idle for 7 minutes and would start to run very rough if you gave it any throttle, ICP would shoot up and it would die. I read and read about problems people were having and came to the conclusion that I may have air locked my lines having undone all of my fuel lines and what not.. Banjo bolt removal for air bleeding is in no way a fun task. The whole front accessory system has to be removed and swung out of the way on the front and the rear passenger was nearly impossible to get with the downpipe in the way. But I was determine dot get it because after all this I was not removing the downpipe. Cracked them one at a time turned the key over and bleed air from each bolt. Tightened them down and proceeded to fire it back up. Still ran rough. looked over my entire fuel system and found not a fuel leak but a air leak pre pump on my fuel filter setup. One of the 1/2" WIX housing threads was not sealing. Since it was pre pump there was no pressure it wasn't leaking but when the demand for fuel was asked for by the pump it was pulling in air and causing the truck to die. Not even sure how we found this. [/QUOTE]
