The only thing that causes this is a defective gas gauge sending unit, it is located inside the fuel tank, replace it.

It sounds to me like your wiring to the tank has gotten broken or unplugged, that would make your fuel pump not work as well as the gauge. Look underneath in front of the fuel tank.
alsoyour could get a fuel pressure gauge and check the pressure at the fuel rail on the engine. if you have pressure there then you crankshaft position sensor might have gone bad.

The sending unit may be shot. Otherwise you may have a blown relay to sending unit in the tank. Possibly fuel pump and sending may have blown fuse.

My 1998 Hyundai Elantra will not start after running out of gas.When I put gas in it ,it would crank but it took a long time to start. I drove it 3 miles and it shut off. I cranked it and cranked it,but it...


Don't let the car run out of gas. Fill the tank and run until the tank is half empty. Again fill the tank.
By driving until you run out of gas, you are letting sediments/dirt collected in the bottom of the tank to enter the engine. Rather they will block the fuel filter. Then gas will not reach the engine.
Clean the gas filter and your car will run fine.
The same advice again. Don't drive until the tank becomes empty.

Truck ran out of gas changed fuel pump and fuel filter still didnt start used stater fluid started up but wont crank unless i use starter fluid what could be the promblem


You aren't getting the fuel up from the tank yet. By running out, and also by changing the fuel pump, you have completely emptied the lines. If it doesn't come up within a reasonable time, check again that your new fuel pump is bringing it up. Also check your new filter, because it may be blocked already. By emptying the tank, as soon as you put fuel in you will **** up any rubbish on the bottom of the tank, which would normally float harmlessly in the tank. There's a couple of starting points for you.

Cant gas to go through injectors


injector pulse is conrolled by the computer and the spark is controlled by the inghtion mudule. even though the spark is happening the computer gets it's pulse information for the inghtion module too. So the ingtion module ( in the distrubutor ) can be bad on the injector circuit. If the fuel pressure is too low the fuel won't flow either. On Vortec engines the fuel pressure has to be 50 PSI or higher or it won't even start. The throttle body engines have to have 20. If not the fuel pumps hose inside the fuel tank may have a whole in it so the pressureized fuel from the pump just leaks back into the tank as the pump is in the tank. This happens alot. The injectores ( in the throttle boby) ( you did'nt mention the engine in yopurs) should have power on the one wire with the key on. The other wire should have a pulsing ground as the engine is cranked. To test this, connect a test light to the battery positive and the pointer to the wire and crank the engine if the light flashes the circuit is good and if the power is good this circuit is'nt the cause of your problem. On the throttle bobvy engines theirs a tap in the fuel line going to the the throttle bady near the back of the intake. a pressure gauge can be connected here to check the pressure. some don't have this fitting and you have to remove the fuel filter and put a tee connection wher the filter was and check the pressure there,. The fuel filter is inside the frame rail on the drivers side 1/2 way down the side on the truck, towards the center of the truck. Fuel pressure is a common problem.

I think I may have gotten some bad gasoline. The tank was empty when I put about a half a tank of gas in the car. After about 5 miles I stopped at a red light. When the light turned green, the car...


the reason is probably when it was run to empty, you may have picked up the crude from bottom of tank. check fuel filter, that may be the cause a plugged fuel filter!!

Starter cranks but engine will not fire. No check


when it does not start put fuel gauge onto injector line see if you have 32-40psi with key on and cranking then check for spark it also would be good to have a scan tool with data to see if crank signal is present

Grand Am won't start.


check for spark while cranking
there is a fuel test port under a black cap on the fuel rail press the valve in and see if there is fuel that shoots out. but crank the car a few times first and build fuel pressure. if not the fuel pump is the cause of everything. change the fuel fitler too. clogged fuel filters lead to damaged fuel pumps

The tank was filled with diesel


you'll need to remove the tank and drain it and clean it. replace the fuel filter and unhook the fuel line from the injector... turn the key on and let the fuel pump run till all you are getting out of the hose is gas.
