How do you check the inertia switch ?FordMan59 said:Check to make sure the inertia switch hasn't got tripped. if it hasn't try turning the key to the on position while listening for a hum frm the fuel pump. If you don't hear a humming that lasts for about 1-2 seconds your fuel pump has probably gone out. To replace it you'll have to drop the fuel tank and remove it from the opening in the top of the tank.
Pretty sure its mechanical. The fuel line is dry to the inline fuelFordMan59 said:Yeah, that's right I don't think they started fuel injection till '87. Does it have an electric fuel pump or mechanical? I too would be leaning toward the fuel pump.
