Fuel pump problem.
I have a 2000 f350. Lost power whole driving and won't start back up. I have checked all my fuses and relays several times. Have no power to the fuel pump. Tried running a hot wire straight to the pump and still nothing.checked my emergency cur off switch and there is no power there. Also my WTS light isn't coming on now. Tried checking the heater bowl and no power there. Any ideas or help would greatly appreciate it.

No WTS light "usually" indicates the PCM is not getting power or, the PCM has given up the Ghost. Do you have reference voltage on any field sensors? That is a good indication the PCM is working.
As for the fuel pump, it should spin when power is applied. But you'll need to ground it as well. The PCM Ground Switches the Relay for Power. If you can get a Test Gauge, I would test the Pump again with 12 VDC.

Fuses can sometimes look good but still be blown....
