Have 2008 ford focus. Had issues with it starting, got it started (using starter fluid) but everytime i give gas it dies.


the fuel filter is not in the tank,the fuel pump might be thats why you need the haynes repair manual to see where these items are located,fuel filters are usualy outside the tank on the fuel line and the fuel pump might be able to be accessed under your back seat or trunk,but you would need the manual to know for sure or look it up on a search engine

I'm told my dad's car 1994 pontiac grand am needs a new fuel pump. where is it located? under the back seat or within the gas tank?


Hi, the fuel pump is located in the fuel tank and to get to it you have to lower the fuel tank from the car, make sure you have used all the fuel up as it will be to heavy to handle if the fuel is left in it,
you need to make sure the car is high enough off the floor to get the fuel tank lowered enough to get the tank lowered.

if your doing this yourself then make sure you have some good axle stands to put the car on before you do any work under neath,

check under the back seat to see if their is an access panel to the tank but im pretty sure their isnt check first just in case im wrong but from what i remember you need to lower the tank down to get to the pump.

Where is the fuel pump located in the motor of a 1991 Honda Accord LX?


The fuel pump is probably located at the fuel tank. You will find the fuel pump mounted on the top of the fuel tank. There will be an access cover, about the size of a saucer, glued down with caulk under the trunk carpet just behind the back seat, or under the back seat bottom. Once you have located this cover, pry it up--I don't think there will be any screws. You should then be able to unscrew the plate from the top of the tank which will lift the fuel pump and sender unit. PLEASE OBSERVE EVERY PRUDENT PRECAUTION FOR WORKING AROUND FLAMMABLE VAPORS AND LIQUIDS! EVEN IF THE TANK IS EMPTY!
THE FUEL PUMP IS INSIDE THE GAS TANK. GOT TO DROP THE GAS TANK TO CHANGE IT.

1991 honda civic fuel pump replacement


You will need to remove the back seats and you will see the fuel pump in between the back seats and trunk. Run the car, remove the fuel pump fuse to relieve the pressure and then the car will die. Remove the pipes to the fuel pump, replace it and refit the pipes. Pump the gas pedal a few times and start it up (remember the fuse!)

If it is inside the tank (the fuel pump), then you will see the tank is held on by straps. Take them off, have ajack under it and remove the filler neck and screws holding it to the car. Remove the tank, undo the central bit where wires and pipes come out and slide the fuel pump out, replace what you have just done and refit.

Hope this helps, please vote :)

I have a 1995 Mazda MPV,V6,4x4,I think the fuel is not working


Don't drop the gas tank. Pull back the carpet in front of the rear seat and there will be a square cover closer to behind the passenger seat with 4 screws holding it down. Remove that cover and it will expose your fuel sending unit cover. This will be circular in shape with 6 or 8 small philips head screws holding it in place. Unfortunately they will probably be very rusty and hard to get out. You will first need to disconnect the electrical plug and the 2 fuel lines. After removal of the fuel lines and the screws carefully remove unit to expose fuel pump.

You can check under the seat of the Stratus for an access point. But unfortunately I don't think there is door. You are going to be pulling out the tank.

Remove back seat to get to gas tank to see if feul pump is working


If you ran the car out of gas, there is a very good chance that the fuel pump is dead. Gas is coolant for for the pump like anifreeze is for the engine. The pump has now been overheated and will need to be replaced. You must drop the tank to do this and I hope you did not fill the tank. It is a very good idea to never run your fuel tank below 1/4 because you stress the pump if you do.

You will have to remove your back seat to gain access to fuel pump. Fuel tank is located in trunk. No need to take fuel tank down.
