If you have a test light and you know there is no power at the pump, work backwards along the wiring and find out where the power is interrupted- you will need a wiring diagram

Check fuel shut off switch in trunk,should have red botton on top, push button and you will reset switch, it is a magnetic switch two magnets and a round steel ball inside, in case of impact accident the ball comes off and shuts fuel off. the magnets will get and if you hit a bump to hard in could cause switch to open and kill the fuel pump. If all else fails unplug swich fromharness and put in jumper wire, temparary only.

Check your oil. Oil press sensor will turn the fuel pump off if there is no oil pressure

Oil pressure switch only will keep fuel pump running if fuel pump relay fails.

Car has been setting for 5 years. Checked fuel shut off switch is good. Checked 20 amp fuse is also good. Fuel pump relay is not getting voltage. I have replace fuel pump relay with ECI relay to make sure relay was not the problem. Currently relay is not being activated.
