Gas gauge if the gauge stops working and it won't start does this mean the fuel pump is no good

check your fuel pump relay. if not that, then it's your fuel pump. the gas gauge is in the fuel pump, so if your fuel pump stopped working, your gas gauge won't work

It says The fuel level sensor is integral with the fuel pump module. Which means you will have to replace the fuel pump,here's how to do.

Just because it pumps gas doesn't mean it is at the exact pressure it should be? Most fuel pumps have a psi of 40 to 45 psi, your fuel pump could be pumping at 25 psi or less which is not enough to start your car even though you can see some fuel pumping out. A simple tool to check fuel pressure can be bought at any auto parts store, check the specs on the fuel pump for your 02 Chevy first to see at what pressure it works, then use the fuel pressure gauge to check it. Anything less than what the specs on your fuel pump are suppose to be and you have a bad fuel pump?

Let's say your fuel pump works at 43psi, you hook up the fuel pressure gauge and you find that it reads 25 to 30 psi, that means it's not enough fuel pressure to start your engine.

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.

Check your battery and alternator connections for tightness. Does it crank over, but won't start? If it won't even crank over, then likely some connection did come loose, like an alternator connection, possibly your fusible link (near the battery).
If it does crank, but won;t start: You'll just have to start from scratch to find the problem. Try to determine if it's fuel or ignition-related. Check for spark at a plug wire. If you have spark, then ignition is not the problem. Check if your fuel pump works. When you turn key on, you should hear the pump buzz on for a couple of seconds. It should also be on when cranking and running, but you can only hear it, or should, when you first turn key to on. If your toyota has a schrader valve on the fuel rail (a valve for checking pressure-it looks like a typical air valve, like on your tire, but is for attaching a fuel pressure gauge) if it has one punch the center with a little screwdriver-gas should shoot out if you have any fuel pressure, If not, have your fuel pressure checked.good luck.

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.

do you mean the truck won`t start and run or do you mean it won`t turn over with the key.if it won`t turn over with the key the you may have a starter problem.if you mean won`t start then it could be the fuel pump not working.with someone cranking the motor you should hear the fuel pump running with the gas cap off and listening at the filler neck.or hear it running listening under the truck at the gas tank.if you don`t hear it then you can hit the tack sharply with your hand or a rubber hammer,it hear the pump start to run then the fuel pump needs replacing.if not check the fuses under the dash and under the hood.if they are good then it may be the pump relay in the relay box under the hood and it should be marked on the box or lid.

Hi!

There is a fuse for the GAUGES, but if it was blown, nothing will work. If your Gas Gauge is acting erraticaly, the problem is most likely the Fuel Level Sending Unit, part of the Fuel Pump, unless you want to remove and replace the fuel pump, your problem will be there til then.

Note, the failure of the Sending Unit does not mean there is something wrong with the fuel pump.

Good Luck!! Don't forget to rate this post!!
