There is a fuel pump relay and fuel pump fuse. It's in the fusebox under the hood, it should be on the driver's side wheelwell. There isn't really any sensors that would not allow the fuel pump to run.

Their is an oil pressure sender on the rear of the engine that will kill the pump if you lose oil pressure, and their is a sensor in the lock cylinder housing in your steering column that will kill the pump if it doesn't read your ignition key properly

SOURCE: no power to fuel pump

What you need to do is drop the fuel tank and put a new fuel pump in it. I would drain the gas and put new gas in after you get the pump changed.

SOURCE: replacing fuel pump relay switch, need to find

There is a black box under the hood on the drivers side of the vehicle in front of the brake booster. The top pops off and the fuse relay is a square 4 or 5 prong block fuse under there.

SOURCE: 2007 Jeep Wrangler Unlimited Crank-No Start. Replaced FP.

starter relay and fuel pump relays should be inside the power distribution center near the battery generally they have a map printed into the inside of the cover. sounds like the starter relay failed during testing and pump relay failed causing the no-start. Strange noise could be a connection problem on underside connection of distribution center.Often, if you try to jump "through" a dead battery it will throw voltage off and systems will not function properly. Jumping from another vehicle can also cause damage to other vehicles charging system. charge your battery and if you need more power while testing, jump to another battery not in a vehicle before you begin, that will add time before system looses power. Also leave one terminal secure enough to be functional but loose enough so that if starter again remains on, you can quickly disconnect it.

If the crankshaft sensor is bad, ECM will give no voltage to the pump. It is design to stop the pump running in a case the engine stop during an accident. Check it out. Good luck.

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

Fuse and relay for the fuel pump


The fuel-pump relay unit is responsible for turning the fuel pump on when it detects the engine is running. When the ignition signal stops, the fuel-pump relay switches the pump off. Problems with the ignition and starting the vehicle often can be traced to the condition of the fuel-pump relay.

Description

  • The fuel-pump relay is a small unit, typically enclosed in a plastic case. The unit contains several sprockets on one side that are clipped onto the ignition system. The fuel-pump relay is engaged only during the start cycle. If it is faulty, it can take longer to start your vehicle.
  • Location
  • Most fuel-pump relay units are located under the dashboard near the steering column. In some cases, the unit is located in the area where the steering column is mounted or near the engine's firewall. The end of the fuel pump relay is typically located near the center of the floorboard, under the carpet in the front section of the passenger's or driver's side footwell.
  • Considerations
  • In addition to difficulty in starting the vehicle, symptoms of a poorly functioning fuel-pump relay include the following: the car dies then starts a few minutes later; the fuel pump makes a strange noise (humming or clicking loudly) for longer than five to 10 seconds after starting; or the engine won't start after you have engaged the fuel-pump switch.
  • Troubleshooting
  • When your car does not start properly, you can conduct a fuel-injection relay test. Two relays are located inside the fuel-injection system; one of them is responsible for turning the ignition on without turning over the engine, and the other is responsible for turning on when the engine turns.



    You can check to see if the first relay is working by touching it while turning the ignition on and off. You should feel a "click" every time you switch the ignition. If the fuel-pump relay is not working, you can "jump" the unit with a small lead jumper cable. You will need to access the fuse panel and insert the cable into the relay unit; the unit will run as long as the wire is inside the relay and can help start your car.

    My 1997 850 will start but won't say running but it will start right up again and then it stops again over and over.


    The fuel pump relay is shot so get a new one for it at your dealer that sold this vehicle when new. That way you can find it easily and also ask the parts counter person to show you the location of it. All you do is unplug the old one and plug the new one in. More than likely the oil pressure sensor is working well for the fuel pump works of that upon when first started up. After the oil pressure is operating at the normal range which takes seconds to do the computer shuts that circuit off to the oil pressure sensor and turns the fuel pump relay on to keep the fuel pumop running until you shut the engine off

    1994 Plymouth Grand Voyager 3.8 eng won't start


    Check primary voltage at ignition coil and fuel injectors, engine cranking, use a test lite, dark green wire with orange tracer. If no voltage, that comes from asd relay. Some makes and models if the computer doesn't see the cam and crank sensor signals, the computer won't ground the relay.
    You need to do some testing.

    Fuel pump relay for a 1994 Chevy Truck WT1500


    The Fuel Pump Relay is located in the Glove Box under a little cover on the upper left side. The Fuel Control Relay is the left relay and The Fuel Pump Relay is the right. To test these relays, swap them and then try to start the vehicle, or blow the horn. If the horn blows then use that relay for the pump and you may at least drive the vehicle where needed! If the vehicle starts, then replace them as a pair.

    Fuel pump shut off switch


    no it doesn't. the fuel pum has a relay that is located in the junction box under the hood if your vehicle is not starting because your not getting fuel check the relay. I use the a/c clutch relay to switch with the fuel pump relay if the vehicle starts just replace the relay if the vehicle doesn't start then you have a bad fuel pump...please rate
