My 2001 f150 will crank but when I try to give it gas is starts sputtering and dies. Then it won't crank again for a while. I changed fuel filter, checked fuel pump, checked coil. Fuel pump pumping strong and coil has correct resistance. Could this be caused by cam sensor or crank sensor or do I need to start somewhere else?

Use a fuel pressure gauge to check the fuel pressure
check MAF sensor
check compression and base timing
check exhaust back pressure

You wouldn't believe what the problem was. I got to checking sensors and just going over every inch of the engine trying to find a reasonable excuse for the way the truck was acting. What I found was the harmonic balancer had slung loose and slid back on the shaft and literally rubbed the crankshaft position sensor until it grounded out causing eratic firing.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
