In your owners manual it will show all the fuses/relays and what their purpose is for. however you don't have to pull the fuse to change fuel filter just leave vehicle off. there will be just a little pressure but nothing to be concerned about. when you pull the line off the filter just remove slowly and the fuel won't spray everywhere. hope this helps....please rate this.....thanks

My 1998 monte carlo runs as long as u put gas down the multi thing changed the fuel filter wat could it be gas goes threw the filter


Is the fuel pump turning on? You should hear a 2 or 3 second buzz or hum from the rear (the pump will be on for that long) when you turn the key to on. If you hear nothing, check the fuel pump fuse, could be in the fuse panel inside the car, or under the hood in the relay/fuse box.
If you don't hear it, the pump may have failed. To be certain, one needs to check if there is any gas under pressure at the engine. Or one could check for power at the fuel pump connector when the engine is being cranked over-if power there, but pump does not work, pretty certain it is a failed pump-tank will have to be removed to change the pump.
If the pump is working, next thing to check would be the fuel injectors and injector circuit. There should also be a fuse for the injectors-probably in the under hood fuse box.

1998 chevy 3500 5.7l idols good when you mash gas cuts out..new plugs,dst,fuel filter,o2sen,new fuel & pump,HELP


my first guess would be fuel pressure , if your sure that the new pump was installed correctly then check the fuel pressure regulator for vacuum. If you have vacuum change regulator. before you do any of that check every single fuse in every fuse panel. most cars have multiple fuse panels.

Honda Civic Coupe. Year 2000 1.6. How can I depressurize the fuel system easily to change the fuel filter situated in the engine compartment.


Hi,

IMPORTANT: Do not skip the fuel system pressure release step. Injury and other damage can result!
Safety Step! Relieving Fuel System Pressure
· allow engine to cool
· relieve fuel system pressure
· put on your eye protection
Before you begin the job of replacing your fuel filter, you must relieve the pressure in your fuel system. A fuel injection system operates under very high pressure. If you don't release this pressure before you start unscrewing fuel lines the result can be explosive. Do this before you attempt to change the fuel filter.
To release the pressure in your fuel lines (and fuel filter) you'll need to locate the fuel pump fuse in the fuse box. If you don't have a fuel pump fuse, find the relay that operates the fuel pump. Once you've found the fuel pump fuse or relay, start the car. With the engine running, pull the fuse or relay out. If you pulled the right one, the engine will quickly die. Since it's using all of the pressurized fuel in the system, the fuel lines won't be pressurized when you crack the fittings on your fuel filter.
Now that you've relieved the fuel pressure you can remove the old fuel filter.
If you didn't do this yet, you must go to the previous step and do it. Very dangerous!

Best regards.

Fuel pump fuse keeps blowing on 99 dodge neon. Changed relay, but didn't help. Fuel pump or something else? It mainly does it when you hit the brakes.


Usually if a fuse blows when applying something else( brakes) indicates they are on the same circuit. Verify the brake lights don't work when the fuse is out or blown. If lights still are working then it's probably not related. If on same circuit then the extra load of the brakes is enough to blow the fuse. Insure you are putting in the correct fuse. Also, this indicates you fuel pump is in a strain either due to restricted fuel filter or worn pump. Replaceing the fuel filter now will only buy you a little time before the pump goes on out. It's blowing fuses because it's drawing more amps in order to run, but always replace filter when replacing pump.

BMW 525i will not start


There are six fuse panels for an E39 BMW
Fuses F1 - F45, fuse panel 1, glove compartment. Twist white plastic retainers 90 degrees and pull down from top of glove compartment.
Fuse 31 (10 amp) protects fuel pump relay(K96)

Fuses F46 - F6, fuse panel 2, trunk located behind right side luggage compartment interior panel.
Fuse 54 (15 amp) protects fuel pump relay(K96)

Before I would do any of the following, I would check the above fuses and put a bottle of HEET into the fuel tank. Fuel filter changing is not hard, but it will take you about an hour.
The fuel pump is another story (BMW has a special spanner wrench(16 1 020) to remove and install the threaded collar.

E39 BMW use a two-lobed fuel tank(think saddle bag like). Each with its own fuel level sending unit that has a float connected to a variable resistance wiper contact. To equalize fuel level between the two tank lobes, a siphon pump is installed in the left lobe. The resistances need to be approximately the same. The fuel pump is on the right lobe under the tank sending unit beneath the threaded collar at the top of the fuel tank which is accessed by removing the rear seat cushion. WARNING When removing the fuel level sender or the fuel pump, the fuel tank should be drained to 1/4 capacity or below. The fuel in the fuel line is under pressure (45-75 psi). Always unscrew the fuel tank cap to release pressure in the tank before working on the tank or lines. Disconnect battery negative cable.

The fuel filter is located beneath the center of the car near the driver's seat usually under a protective metal cover held on by small screws. Not hard to replace but car will need to be on jack stands and 1/4 tank or less of fuel in the tank. Definitely wear safety goggles or face shield as the fuel will come out on face. Have a fuel catch pan under the filter. Clamp the fuel line before and after the fuel filter(long metal cylinder) before loosening hose clamps. Loosen center clamping bracket and hose clamps on either end of filter. [Some have an inline fuel pressure regulator.(Remove vacuum hose, pull out locking clip, remove fuel pressure regulator).]
Drain fuel from inlet side of filter and check fuel for rust moisture or other contaminats.
Installation is reverse. When installing fuel filter, ensure fuel flow direction arrow points to front. Should have at least 5 liters of fuel in tank before restarting. The fuel pump will be damaged if run without fuel.
