Find and check the fuel pump relay. You can test it with an ohmmeter. Place one probe on each side of the relay. It should have a good reading.
Also, when key is place in ON position, you should hear pump turn on for a few seconds. If not, check wiring to pump and to the relay with a voltmeter and see if there is power.

Did the engine just quit going down the road? or was it parked and then would not start? Did it have fuel before you replaced the filter? Did you check all the fuses in the fuse box. I think 2 of the fuses is marked ECM, check both Fuel pump relay? swap it with another relay in the fuse box. You should hear the pump come on for 2 seconds when you turn the key on, do you? If not as you are cranking the engine have someone rap on the bottom of the fuel tank with a mallet or block of wood, or hammer and see of the pump will run. If that gets it running, the pump is bad and will need replacement.

Engine runs rough under 2000 rpm


A possible cause may be bad plugs/wires, or a poor fuel flow. It is recommended to change the fuel filter, air filter, plugs and wires, as all engines require this maintenance after so many miles/kilometers.

1992 F350-7.3 4wheel drive is hard to start after changing fuel filter and fuel pump. Why is it hard to start?


indicates fuel leak back and fuel pressure drop
check filter installation for seal not sitting properly, loose fuel line fitting , pump installed correctly (flow wise ), filter installed correctly (flow wise)
air getting in to fuel lines
the thing you are looking for is indicated by the initial hard start but when started runs ok ( good fuel to the engine eventually) and then by the fact that if the engine is allowed to sit for a long period the problem returns meaning that the fuel pressure is not being held
could even be a problem fuel pressure regulator allowing the fuel to bypass ( no pressure =hard starting) then gets enough pressure to run ok but allows that pressure to drain off over time

2000 Grand Vitara breaksdown, backfires and dies while driving after about 30 minutes. Starts again in about an hour. Changed fuel pressure regulator. Made no difference.


The check engine will be on if the key is on but engine not running . This is normal. If the check engine goes out when the engine starts there are no codes present . Did you check the fuel filter . Sometimes when a filter is dirty there is sedement laying in the filter canister . When the pump starts working the flow picks up the sedement and plugs any remaining open screen and stops the fuel completely . The engine stops . When the flow stops the sedement falls back allowing flow again. and the engine will run for another while . If the filter is old it should be changed anyway . Also when the engine stops check to see if there is spark at the spark plugs while cranking the engine .

My car bucks when driving it will die repeatly engine will race. shut it off for a little while start again and it will be fine for a while then will start doing it again


Lawn mowers have had that problem before and what it was is rust or a object in the fuel tank blocking the flow of gas you might try changing the fuel filter there could be contaminate in the fuel line one way to test that would be to disconnect the fuel line from the engine and aim it in to a gas can and have some one turn the key to the on possition watch the flow to see if it sputters if it does theres the problem , then you should replace the fuel pump and filter as well as the inline filter.

I have been told that my 1999 Cadillac Deville may be experiencing hesitation and rough running because the fuel filter may need to be replaced. Are there any instructions for that?


First we need to check if really fuel filter is at fault for rough running. Open the bonnet and pull out fuel pipe from the engine. Put this pipe in a clean and empty clear bottle (so that you can see the pipe) and now switch on the ignition but do not start the car, just turn it on. See the flow of fuel, if its constant then rough running is due to something else and if your fuel filter is really clogged then petrol flow will not be constant. To change the fuel filter, get under the fuel tank and locate a plastic cylindrical component with two fuel pipe connected to it. This is fuel filter. Buy a new one and replace. Make sure you check the pipes for any fuel leakage after you have connected the new fuel filter.

Could be a fuel issue, Start by changing the fuel filter, if that doesnt work you might want to drop the gas tank and check the strainer on the fuel pump and make sure the tank is clean.

Losing power when I accelorate.


Fuel filter is the main culprit when you lose power going uphill. Going level or downhill means that the engine doesn't have to work all that hard and doesn't demand much fuel, so a partially clogged filter can usually flow enough to allow the car to run smoothly. Going uphill requires signficantly more fuel, and if the filter is clogged up, it won't be able to flow enough fuel. This will bog the car down and cause you to lose speed. Change your fuel filter.
