Truck was running fine. And then while going down the road truck lost power but continued to idle. Turned truck off. Now it cranks but won't start. Pulled fuel line off of top of fuel pump, crank the engine and fuel comes out for a second or two but then immediately stops. What is causing the fuel to stop after a second or two?

The fuel is working normally, changes are the crankshaft sensor or MAF sensor has gone out, I would run the codes to see if any are stored so we don't go in the wrong direction when fixing the problem.

This video will help us see which system is missing and I have included the crankshaft sensor in case there is no spark:
