I have a 1992 honda accord ex that ran great until one day I was running low on gas and it started serging like running real high, then real low like it was about to die . Now it starts but when I step on the gas it dies. What is the problem?

Sounds like its trying to **** water drops into the injectors. while water drops are heavier than gas drops. under accceleration they will shut off your fuel supply because waterdrops are larger and more dense than gasoline.and will not pass thru the injector nozzle. remove and use compressed air to blow out and dry injectors, filters and fuel line. and also check your tank,water in your tank will rust the insides of the tank ,as well as the fuel level sending unit and wont do any good for an in tank fuel pump either .
if you have a standard carburetor, this problem can be caused not only by water, but by dirt,or rust particles plugging the small passages . Good luck !

Start with testing to see if you have the correct fuel pressure, and maybe changing the fuel filter. Is there a engine light that is on that you didn't mention. If the engine light is on, we need to get you to put it in self test mode.

To locate the codes that are stored in the ECM you will need to locate the plug on the passenger side, under the kick panel. Where the passengers right foot would be, down below the glove compartment on the side in front of the door. There will be a plastic kick panel, it matches the interior of the car, just pry that off, as it is only held on by clips. It is a two wire connector, you need to place a jumper wire from one side to the next (a paper clip will work nicely), turn the key to "run" or "on" not start it...then count flashes of the engine light on the dash as mentioned above. Codes remain the same. A long flash equals 10. A short flash equals 1. So if you get 4 long flashes that would equal 40.Three short flashes would equal 3. Four long flashes + three short flashes = code 43. you may have multiple codes stored in the ECM and will repeat themselves over and over, there will be a pause in between codes.
