Old school Fords and Chevys had the mechanical fuel pumps mounted to the side of the engine block and were easily accessible. Not any more. The fuel pump is located in the fuel tank and is quite a pain to get to. Your best first step is to remove the fuel line at the intake and see if you are getting any pressure when starting. This will eliminate any doubt as to whether or not it is your fuel pump. There is a good tutorial on how to replace the fuel pump on youtube. http://youtu.be/S5bEAAAloHY Hope this helps and good luck!

do you hear fuel pump kick on when you turn the key?did you check fuel pump relays?if I remember correctly ford still had 3 fuel pumps in 1990.a low pressure pump in each tank and 1 high pressure pump on frame rale.if it wont start with both tanks if its a fuel pump issue its problely the high pressure pump.
