Simple enough. pull the harmonice balancer, aka the crank pulley. remove the crank seal and there is the low pressure motor oil pump for the 7.3
First, Remove the fuel Pump Relay then crank the motor for few seconds. Stop the motor, put the fuel tank down and disconnect the plug from the fuel pump.
the oil pump is on the front of the motor you have to take off the crank pully it is behind it there are two gears that you will need to replace
There is no fuel pump shut off on most gm but you can take the fuel pump relay out or the fuse and crank the motor to relive the line pressure.
No. Almost always the oil pump is mechanically driven by the rotation of the engine. When you turn it over, the pump also turns.
Disconnect the fuel line and crank the motor for for 7 to 10 seconds for three tries. Reconnect the fuel line. Pump up the primer bulb pull, out the choke and attempt to start the motor
fuel pump relay or could be a camshaft or crank sensor have computer scaned for trouble codes before you do anything. your description i understand that engine cranks but does not start correct?

its not the crank sensor , cam sensor , o2 sensors , not the fuel pump relay, maybe the coil not sure tho
If by "crank" you mean that the engine isn't even turning over on the starter motor, then you really should have looked at the starter, the solenoid and the wiring before tinkering with the fuel pump. A healthy engine will turn over with the starter engaged regardless of what's going on with the fuel pump or ignition system.
On a 2002 Taurus with a 3.0 12 valve flex fuel motor, the belt routes from the crank pulley, clockwise to the tensioner, then around the water pump, next the alternator, next the idler, next the power steering, and finally around the air conditioner pump, which leads back to the crank.
in 82 there were no relays controlling the fuel pump it is mecanically driven off the motor no electric its driven offf i believe the cam or crank not shure which one without going out side to look at mine.
