Help! 99 f350 won't start
E99 started and ran good after hutch and harpoon mod. Idled in driveway for over 30 minutes then went on a drive about 12 miles in it starts acting like it running out of fuel. Running rough and missing, so filled up with fuel while idling , made it another mile before it dies completely. Had towed to house, checked fuel bowl and wasn't getting fuel even though fuel pump was running so installed new fuel pump, replaced all fuel lines and added a prep ump filter. Primed system, started and idled rough but was getting better then got worse and died. Checked fuel bowl again, it was full so drained and cycled key, fuel bowl filled up but was kinda foamy. Reinstalled filter and it started and ran but then died again. Seemed like if you cycle the fuel pump a few times it will start and run for about 3-4 minutes then gets rough and dies. I'm ata a lose here as this is my daily driver and has run perfect till the hutch/harpoon mod. If anyone could help,and point me in the right direction it would be greatly appreciated.
Just checked no trouble codes, and if I remove and reinstall fuel filter it starts and runs but runs rough and dies. Seems like I'm catching air somewhere, my new prepump fuel filter is clear and fuel is getting there clear. Also on a side note when I removed my fuel bowl cap it had a lot of pressure on it, this has never happened when I changed fuel filter previously.
