Fuel pumps bind up when they are beginning to fail. as the pump motor wears it starts to overheat, causing the armature to get stuck. Dry gas likely has some cooling effect and banging on the tank jars the armature free.
Replace the pump assembly and you should be good to go!

Disconnected battery and reconnected it and car will crank over but will not start

Could be several items:

Would start with fuel pump. Can try banging on tank (if its in the tank) or tap on pump if outside.

To test fuel pump:

Locate fuel filter, disconnect line and on the exit end of the fuel pump. Turn ignition on and attempt to start. Be careful no open flames, or spark cuz if fuel pump is working gas will come out.

If no fuel now disconnect other end of fuel filter. Fuel filter is now removed. Try starting vehicle.

Note in most cases it will only put fuel out for 2-3 seconds to prime the fuel lines and then goes out for 5-10 while vehicle starts, then turning back on.

Having someone to help look will help when checking this. If fuel comes out now then the fuel filter is plugged. If nothing then fuel pump is toast.

Look up on YouTube how to remove fuel pump from either in tank or out of tank.

Ran out of gas put gas in and now the car will not start

Running out of gas on a fuel injected vehicle, is very bad. Mostly, due to the fuel lines get pumped up with compressed fuel vapor. The pump can quit from running dry, & need replaced. See if youcan find the shrader valve on the fuel line, easily found on most GM's, usually none on Fords. I sometimes crack the rear fuel line (steel) on end of fuel rail. Crank a few times with the ECM fuse out so it cannot accidentally fire, if fuel comes out. Another alternative, until the fuel pump get fuel to the fuel spray a few short shots of "starting fluid" on the air filter. (about a 4 second count). SpraY; 1 ONE THOUSAND, 2 ONE THOUSAND,3 ONE THOUSAND, 4. No more than that, then put the filter back in, close the box quickly,without snapping in & crank. DOes it run then, if it sputters & spurts, proably needs a fuel pump. On fuel injected vehicles, they are usually in the tank.

92 VW Jetta ran great one day and wouldn't start again. Daughter ran it out of gas, changed the plugs, put gas and gas line anti freeze still nothing. thinking fuel filter, are there 2 filters? and where...

First, you should Make sure that is the problem. Usually if your filter is clogged enough to kill the car, if you wait 10 to 15 minutes the car will restart. The fuel will eventually seep thru the filter. You more likely have a relay or fuel pump problem if it is fuel. Try removing the air filter and spraying carb cleaner into the intake, if it is a fuel problem, it will start. If it is a spark problem it will not. Most vehicles have a filter inline about half-way between the tank and the engine underneath the car. If you jack the car, trace the 2 lines from the fuel tank tds. the engine. There will probably be a cover to protect the filter.

1998 windstar sat for 3 months while my sis saved up money for a new starter. I put in a new starter and it spins over great but will not start up. I believe that there is water in the gas tank and it...

IF your problem is water in the gas tank you'll need to buy some gas line anti-freeze, add some gas and get the car into a warm garage to thaw the water in the fuel. The gas line anti-freeze will break up the water and allow the vehicle to start but don't be surprised if it sputters a lot a first and less later. Tip:make sure you buy the right stuff for fuel injected system.
Good luck.

1992 Chevy Lumina will not start when temp is below 0 degrees

Try changing the fuel filter, water trapped in it can freeze. Its a 92 and probably time for a fuel pump. They don't like water either.(Meythonol Fuel) Always change fuel filter when adding antifreeze to fuel
