ANSWER: Get yourself a helper.

1. remove the gas cap and have your helper listen at the gas cap opening.

2. You turn the ignition key to the ON position whereas the dash lights light up, But do NOT try and start the engine.

3. As soon as you turn the key to the ON position, Your helper should be able to hear the electric fuel pump in the gas tank make a buzzing sound for 2 (two) seconds and then it will stop.

QUESTION: yea it does makes a buzz sound then stop. Now it crankes but when i get down in the gas it hesitates then pops like a slight back fire. Or it will cut off.

Answer
Just see if the car will start and keep reving the engine to higher speeds for a few minutes to purge the air.

If the engine still acts up you may have damaged the fuel pump and it is not delivering enough pressure to the engine.

The fuel pump runs so fast that it gets HOT and what cools the pump is thje gas in the fuel tank. So if you keep running the gas near empty the hotter the fuel pump gets and can cause it to fail.
