My car cranks but won't start in the morning

I am having the same problem and I replaced crank position sensor, it was not the problem, I should have looked at the tac while cranking the car over, If it goes up a little off the bottom and stays there while cranking it is indicating the signal being picked up off your sensor. I shot a small amount of starting fluid in intake post filter and the car fired up then died again. So spark is fine fuel is my problem. Checked fuse 29 good, checked power to fuse 29 while cranking had power. Took out relay 219 from under engine control mod I think it is the fuel pump relay it was very warm just after cranking car a few times and failed meter test so I hope that is my problem. only thing left to check is there power to your fuel pump and can you here it when cranking, Or fuel filter could be plugged. hope this helps
