No, no reset switch. Verify power arriving on the gray wire to condemn the pump itself. Very common failure.

I don't do "what ifs". Test for power getting to the pump and we'll go from there. It only powers for 2 seconds when the key is first turned on.

I am having the same issue. I have checked the fuel pump fuse and changed the pump relay. I still am not getting power to my fuel pump fuse. Shouldn't I have power to my fuse before I would have power to the pump? I changed the fuel pump within the last 6 monthts.
