2012 ford f150 cranks but no start
2012 with 5.0 cranks ,no start. good fuel pressure to fuel rail. good spark at
plugs, injector firing. new plugs. fuse and relay good . 50 k on truck. scanner
says 77% alcohol mix in tank. sprayed start fluid in intake ,no effect ????
With all the work you've already done, I'd say it's the crankshaft or camshaft position sensor. I am curious about the alcohol mix. If the scanner is correct, it seems that someone might have fueled up at an E85 pump, and that's not good for the engine or the fuel system. Your truck is made to use E10, and probably E15, but a higher concentration of Ethanol will corrode the fuel system and cause engine problems.
