There is either a ring you rotate by tapping with a drift, or a ring of screws. Then the whole ssending unit plate comes off.

Check to see if timing belt is broken. or wiring to crank-shaft sensor and check sensor itself on front of flywheel typically but may be on side of block usually the further towards the transmission is Crank and closer to front is cam sensor.
Check relays by switching from others of the same numbers.
Crank-shaft positioning sensor is bad perhaps.
Remove plug under vehicle that leads to fuel pump and check for voltage when key is turned on. if voltage is there is either defective fuel pump, was put in wrong or is harness from that point to the pump.
try banging the tank with hammer as someone turns key on.
check harness from fuel pump to where it goes into the body - remove from body plug and inspect.
Should be either and or both a fuel pump relay and fuse!
Run 12 volts to the positive side of the fuel pump wiring to see if pump is good. 3 wires usuallly 1 is ground for both the fuel guage and the other positive for the pump. and other is positive for the fuel pump guage and these two wires for the guage will show some resistance. put a fuse inline with the 12volts to the fuel pump positive but cut the line to the body prior to this - temporarily.
Could be bad switch in ignition unit in steering column but doubtful.
Hope this helps.
