Last night my truck started acting up. Ran fine went in gas station came back out tried to start truck and it just cranked and cranked. had codes P0340 and P0344 for cam sensor faults. I replaced it this morning and it still cranked and no start. Got code P1212 for low fuel pressure. sprayed a little starting fluid in it and lit right up and ran good with no problems. cleared codes and drove for 30 miles. shut it off and went to go back same problem. I can not get to any other recourse today de to the holiday but I do have ground on one pin and 7 volts on another and 12 volts on the other. please help with some feed back. its a 1995 f250
