One day I was on my rancher and it sputtered and died. Would not start again. I turn on the ignition and the fuel pump does not cycle. Both the FI light and temp light blink continuously. I replaced the fuel pump relay and fuel pump and filter still doing the same thing. I'm stumped and don't have a clue where to look now. I checked all fuses and wire connections and all are good. Could it be a sensor or main computer ? Any help would be greatly appreciated.
