1994 Ford Ranger Cranks but won't start

Check your fuzes frist and switch the relay in the box under for fuel pump with another in the box to see if the relay is the problem. When you first turn the key on, you should be able to hear the pump. ---Fuel pump is a fair bet, note that the wires will sometimes rust out. Easiest way to get at it is to remove the bed. Remove the gas cap and 3 screws by it (don't put the cap back on or it will hang up later ) note this is a good time to look at the filler tube and see if it needs to be replaced soon, cracking, its $300 from dealer or about $60-70 on ebay , then remove the bed bolts and unplug the wires at connector at front of box the the bed should lift off with no problem ( 2 person job ) an electric impact with right torx socket works best.
Now you have easy access to top of tank to replace sending unit and pump or pull unit and replace just pump. Trust me dropping the tank is 10x more trouble than removing the bed.
