bad relay? bad ground? could be the ecu.

break out the multimeter and follow the wires, man.

best way to test for fuel would be the pull the fuel line after the fuel filter. this not only checks to see if your fuel pump is working but it also verifies that the filter is not plugged up. plus it's a lot quicker and easier to do.

also, check your plugs as they may also be fouled up. if that is the case, replace them. you can also crank your motor with the spark plugs out to get rid of any excess fuel in the combustion chamber. just make sure you aren't smoking or anything lol.
