Has the check engine light come on? Will the engine start at all? Have you checked fuel pump pressure?

Here is a video that shows how to check fuel pump pressure. There are also directions on our homepage under the DIY section.

You will need a fuel pressure gauge. Most parts stores will lend them out to customers, so check your local parts store.

Let me know if this helps. At least it is a good starting point. Also, if the check engine light is or has come on, have the computer scanned for trouble codes. Again, most parts stores will do this for free.

Let me know what you find.

Its very hard to explain.3 people including myself said it doesnt sound to be comin from the engine. It kind of sounds like something vibrating but when your driving the car you cant hear it. Would it be the spark plug by any chance? Like I said I dont know much about cars. Thanks for your help

Chances are it has nothing to do with the plugs. Is there any way you could video the engine running and the noise and upload it to youtube or something so I could hear it?
