When you turn the key to on position(second click) do you hear a faint pressurisation of the fuel system? Of course turn off the fan and radio to best hear the noise. The noise comes from the middle rear of car under the seat. If that is not happening it may be the main relay instead of the fuel pump itself. Main relay costs $20 used and is easier to change before taking out the fuel pump. Main relay is located under dash drivers side, typically a maroon coloured box with a ten mm bolt holding its bracket. Fuel pump I think is under the seat bottom and is also not too tricky too change. un plug two electric connections take out eight ten mm nuts and then slide out the unit. disassemble out of the car on a workbench to replace the pump and then reassembly reversal of dis-assembly. 3 hours tops.
