Before you rip into the fuel pump, use a pressure gauge to confirm the pump isn't working. If it isn't, then you need to check to see if there is power to the pump. If there is, then chances are the pump is bad. If there is no power, check the fuel pump relay to see if there is power to it and it is working.

The relay clicks when key is turned on. The fuel pump does not make a sound. I was going to put power to the fuel pump directly but am confused by the maze of wires attatched to the top of the gas tank at the fuel pump access cover. Blue Black, brown, green, blue/white, green/white, yellow/white. Can you suggest which one(s) to put power to to see if the fuel pump will run? Or if I put power to the relay, will that provide power to the fuel pump? Thanks. Mike
