I am in need of some immediate help. I removed the npt fitting screwed into the post filter test port on my '99's fuel filter canister and got air into the system. Cant start. I have bumped the starter many many times and cracked the fitting till diesel spewed out and still can get it going. After I replaced the fitting, I bumped the starter several times and she started only to die 5 seconds later... . HELP!!!
