    The fuel pressure to see if that is the reason it's not starting!

    Check for fuel pressure at engine rail. We have taped a pressure gauge to the windshield and driven vehicles while watching for pressure drop.

    When you turn the let on u should hear the pump priming the engine if u don't check your fuses.and maybe use a multi metor and check the volts on the wires going to the pump. If u hear it come on and out won't start try replacing your fuel filter

    AN '09 DOESN'T HAVE A EXTERNAL FILTER.

    Talk about people that think they are experts! You know what i mean!
    Any way this guy takes the car out in the rain for a test drive and you guessed it, them wipers had to be replaced! That is a da.n good test, i have left the gauge on them a couple days before. You do what ever it takes on an intermittent though!

    I'd hate to see the big gauge you would need to be able to see it at your age. By the way- I'm not answering his questions after his remarks. A new one listed now.
