Im changing the fuel filter on my truck and when i turned over the ignition to check the fuel pump, i only get gas from the engine side of the fuel line. is this normal? if it is, what direction do i put the new filter on?

Fuel pump: The fuel pump is responsible for delivering fuel from the gas tank to the engine. If the fuel pump is not functioning properly, the engine will not receive the fuel it needs to start.
Fuel filter: The fuel filter is responsible for removing impurities from the fuel as it flows from the tank to the engine. If the fuel filter is clogged, the engine may not receive enough fuel to start.
Ignition system: The ignition system is responsible for generating a spark that ignites the fuel in the engine. If there is a problem with the ignition system, the engine may not start.
Battery: If the battery is weak or dead, it will not be able to provide the necessary power to start the engine.
To diagnose the issue, you may want to try the following steps:
Check the fuel pump: You can check the fuel pump by listening for a humming sound when you turn the ignition key to the "on" position. If you don't hear a humming sound, the fuel pump may be the issue.
Check the fuel filter: You can check the fuel filter by removing it and inspecting it for any clogs or blockages.
Check the ignition system: You can check the ignition system by checking the spark plugs and ignition cables for any visible signs of damage.
Check the battery: You can check the battery by using a multimeter to test the voltage. If the voltage is low, the battery may be the issue.
If you are unable to diagnose the issue, it may be best to seek the help of a professional mechanic.

check for spark, no spark, no fire engine wont run, possible bad ignition coil, wire from coil to distributor cap, no power to ignition coil from ignition switch (rare) wire broken to ignition coil (even rarer)

the way a electric pump works is the pump uses the gas to keep its self cooled so when you run the car out of gas or low on gas it gets hot and has to work harder but hey what can u do when your broke. that valve on the fuel rail u can use to tell if you getting fuel have someone turn the ignition on and push the valve in if you get no gas then check the interia switch if that switch is tripped it will shut off power to the pump a blown fuse or bad relay can do the same. if all is good there take the bule line off and see if you can get gas to come out there but be careful to not get gas in your eyes if you get gas out there then the filter is plugged if no gas comes out then you got to replace the pump.

If you change the fuel filter and still not getting fuel to the engine, then the other possible problems are:
- Clogged fuel lines due to 'dirty' fuel.
- Defective Fuel Pump which may not provide enough pressure to 'push' the fuel pass your new filter.

Hope it helps.

local libraries usually have haynes manuals to tell you what's where.my fuel pump is attached under the back seat on top of the tank.you should never pump the gas starting fuel injected cars since they came out.however,if your fuel pump was bad,it probably would not start.try air filter and gas filter.if those are fine try vacuum lines.

Sounds like the fuel pressure regulator. Check to be sure your fuel pump is pumping gas up to the fuel rails. You can usually hear the fuel pump kick on at the gas cap. I would change the fuel filter while you're at it. Just to be sure there's no trash caught within the filter.

Look and listen for vacuum leak Free,Change air filter $15, change fuel filter$20, replace fuel pump$300.

With motor running and your head under hood listen for hissing sound. Then start replaceing filters first air filter , then fuel filter. Check fuel pump by listening for humming noise at gas cap when you first move key in ignition to on (when the red lights go on). Have someone listen for you at the gas cap.(NO hum need pump)

Check / change the throttle position sensor yet?

Any check engine light /code to work with?


Did you change the fuel filter when you change the fuel pump.

are you sure lack of petrol was the reason the car stoped. try leaving the ignition on for a whlie and also turning the ignition on and off and leaving it for 10 second before turning of.this will get the fuel pump working, pumping fuel to the fual rail. and building up fuel pressure again.hope this helps

no fuel issue. check fuse for fuel pump check fuel pump fuel pump relay fuel filter could be pluged.if you turn engine over acouple turns and stop you should hear fuel pump buzz.also check wires at ignition coil for corrostion or broken fuel pump relay gets its singnal for negitive side of coil.
