fuel pump not running engine will run if manually primed, fuses good. Is there a test for the fuel pump relay to dertermine if the pump is faulty and what is the procedure? Thank You

There is a jumper wire to the fuel pump. Connect it to 12 volts and see if the pump runs. However if the pump is OEM it's probably toast. The good thing is that the 93 uses a cheaper pump. The easiest way to replace it is to remove the bed. Less danger of damaging the wiring/fuel lines and the tank. Plus it puts the pump at a very handy level to work on it.
