I bought a 2003 F350 with the crank no start issue, 80% of the time it could be started with a shot of brake cleaner or lysol (don't preach to me, i know the dangers) to move for street sweeping, other times it would just crank faster and then slow back down. When I first got it, i took it for a drive for about over an hour straight with no issues ( without shutting it off). It has developed a stalling issue where it will shut off when i accelerate from a stop, when i would go to restart, the injectors wouldnt make their notable loud clatttering but they would buzz or hum for a couple seconds. Even with a shot of brake cleaner it wouldn't start at that moment, it would be fine and the injectors would clatter normally the next day after it cooled off. For a week straight the truck would start up and run normally (still had stalling issue) when it was cold, but would not restart hot. Now the truck will not start at all, there is no smoke or signs (there never was) of trying to start. I have had the truck since November second and i have changed out these parts in the course my ownership:
-IPR
-ICP and pigtail
-One battery
-Oil and filter (Rotella 15w40)
-Cam sensor
-Crank Sensor
I was told the other battery in the truck was relatively new, both are up to spec and have approptriate CCA. I have checked the FICM and during the Injector Clattering and Key on Engine off the voltage never dropped under 45. I have also charged both batteries and made sure the terminals were clean. The oil pressure gauge on the dash moved up about halfway after a few seconds of cranking. I took the valve cover off and the STC fitting on the oil rail looked a little chipped, i also noticed that the wires on the injectors near it are yellowish, compared to the white on the ones closer to the firewall but i cranked the engine over and i didn't see a leak. The cranking RPM is averaged about 140 RPMs in this 38 degree weather here in Jersey. Is there anything I should be looking for besides the basic things i have seen on every forum? Why would it start fine with no help for one week and then not work the next?
