I have a 1995 gmc jimmy with a 4.3 vortec engine and i was driving and engine shut off i do have spark and when i used starting fluid engine started has a good fuel pump and i was told it could be the fuel pump sensor can u tell me where it is located since it is not under hood thx

Had this problem after changed fuel pump. My problem was the fuel pump relay located inside your glove bow on the left side. The relay was not staying tight in the socket and was'nt make good contact. Put small flat piece of wood in front of relays and wraped elect. tape around to keep them tight. Solved problem.

There is not a part called a fuel sensor on this vehicle. If you have good electrical to ingition and no OBD codes witch it is most likely an OBD 11 system the first year for your vehicle. So is the MIL light on service engine light on if no then replace the fuel filter first its under the drivers door mounted to the frame rail also check if the fuel pump is putting out enough fuel and pressure when you have the filter off by turning the key to run and putting a plastic bottle on the line comeing from the fuel pump you should get about an ounce per second from the pump do a 5 second test you should get about 5 ounces of fuel. If you say get one ounce then the pump is no good if its OK then it is likely the fuel filter and this will solve the problem. The reason i'm telling you this is the fuel pumps on these vehicles had problems and unless you or someone else has replaced the pump it is the most likely cause of this problem good luck A nd there some fuel sensors on the fuel pump it self for pressure and gauge control and EVAP emissions control systems that wouldn't stop fuel flow to the throttle body they would just set codes off
