I have a 98 Camaro I put a fuel pump in fuel filter an my car still won't start.Do thank the gas line clog up?


If you know for a fact the pump is getting power and ground, and nothing is coming out of the line before the filter, then yes the line could be clogged up.

Gas gauge quit working, now car won't start


Sounds like you dont have any power going to your fuel pump. You will have to drop your tank and with a light tester check the red wire for power. If you cant tell with one is the red wire it will be the secound wire going into the plug. If you dont have any power there then make sure your fuses are good. You will need help with this because it is very had to reach the key switch and check the wire the same time. It is on a relay switch and only stays on for 5 secounds. Good luck.

I have a 2004 saturn ion and it won't start. I think it's gas related. Where and how do I replace gas sensors/filters or fuel pump? What do I try and replace first? How do I I tell which is bad?


If you haven't replaced the fuel filter in the last year or so, do it now-basic maintenance.
Check if the pump is working by turning key to ON (not crank), and listen for the pump in the tank to come on for a couple of seconds. Should hear a short hum or buzz verifying tank is working. If you don't hear it come on, either the pump is bad, or power is not reaching it. May have to pull the pump connector off at tank, and check for 12 volts on pump wire when someone cranks the car. If power there, the pump must be bad. If no power there at pump, check fuses for pump and fuel pump relay.

Car has been sitting; will turn over but won't start. Used starting fluid and car starts but quits. Won't fire without starting fluid. There is fuel in the tank. Help!!


My first thought is to check the fuel pump operation.
Check to see if fuel pump is getting power.

This is how I check the pump.

Usually there is an in-line fuel filter that can be removed.
While its removed...bump the starter to see if gas shoots out the gas line.
If not, there might be a clog at the pump...or the pump needs replacing.

Hope this helps...

2004 z71 tahoe when the gas gauge is at a quarter of a tank it won't crank. It acts like it is empty with gas.


Check your fuel filter if it needs replacement. Empty it out then connect it back. Try to start it again. Inspect the fuel filter if it filled with gasoline. Check if there is noise at the fuel tank to check if the pump is working. If it did not, inspect the fuse for your fuel pump and the relay. If both are good you may connect the fuel pump directly to the battery to see if it works. It may be a bad wiring.

My van sounds like it wants to start but wont


if it cranks over and won`t start,you need to check for spark at the plugs,if you do then you will have to check the fuel pressure with a gage it should be about 35lbs.if the fuel pressure is not good then the pump will have to be replaced.you should be able to hear the pump run when you are trying to start the car at the filler neck with the gas cap removed or under the car at the gas tank.if you don`t you can try hitting the tank in middle at the bottom and the pump may start and the car will start.either way the pump will be no good.fuel pumps are common.

1997 pontiac bonneville fuel pump pressure not getting enough gas to motor but has power to pump


Hello anthonymike8,

Your fuel pump pressure should be 48 - 55 psi, if it is below that it may not start.

You say the pump has power do you hear it come on when you turn the key on?

Will not start, turns over but fails to start, seems as if it is not getting gas. Perhaps the fuel pump or sending unit is bad. gas guage does work now either.


can you hear the pump run?? if you can i would start by changing the fuel filter before i droped the tank... also did you check your relay for the fuel pump, under the hood?? the sending unit doesnt send the fuel to the engine, the sending unit is what operates your gauge... so, if your pump is junk and got to drop the tank, the sending unit is built in the pump, so kill 2 birds with one stone, and replace the fuel pump assembly, and everything will work.
hope this helps
