QUESTION: check engine light is not on its not getting fuel

Answer
Perform this test procedure using a helper.

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

2. You turn your ignition switch to the ON position where the dash lights light up, But do NOT start the engine.

3. Your helper should be able to hear the electric fuel pump make a buzzing sound for only 2 seconds just as you turn the key to the ON position.

4. If your helper does NOT hear the fuel pump run for the 2 seconds, and If you are mechanicaly inclined or know of someone who is, You will need a DIGITAL MULTIMETER, Simple electrical schematics, Test procedures and picture locations of the fuel pump system components  that is causing you problems of which can't be done on this website which only allows one picture. I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
