fuel filter? how about power to the fuel pump,loose ground wire to chasis? wiring harness? terminals clean at point of connection?did you check the fuel pump relay? Relay is located in electrical center under the hood on the driver side.relay and fuse legend will be on bottom side of cover, you sould be able to switch with another relay that you know works, ie: switch horn relay with fuel pump relay, honk horn to insure both relays are working when either relay is inserted into horn slot. Do you by chance have the electrical schematic drawing for the fuel pump?

You must remove the fan belt first by wrenching the spring loaded tightener and the same must be done for the compressor belt.

Keep throwing belt

If the alternator is on the same belt as the water pump, I'd suspect that the water pump pulley is not in line with the alternator and crankshaft. Stand to the side and look at all the pulleys on that belt. They should all be in the same plane, and the belt should look like a straight line over all the pulleys. If not, check with where you got the water pump to see if there are different pulleys, depending on application.
