1996 f350 7.3 dead
i have a 96 f350 7.3l it popped a p0340 code and started running really rough it would not pull a hill if it didn't have a run at it i replaced the cps and fuel filter. still the truck wouldn't start so i checked the fuel pressue it would fluxuate greatly between 25 and 50 psi while cranking and bleed off pretty quickly after stopping so i replaced the pump still the same. now i am getting a off and on p1280 or a p1111 code and the truck still wont start . any ideas would be great.
