    03 Grand Am No Start

    This 03 Grand Am w 3400eng has me at wits end. When cold it has no injector pulse, has spark, has both crank signals, and has cam signal to PCM.MODIS reads "cam signal__no". Here is the crazy part,give it a shot of starting fluid and it starts and runs like a top,and will restart all day until it sits for a long while{overnight}. any ideas????

      Have you checked out Shopstream Connect w/ Ask-A-Tech Live? http://www1.snapon.com/display/1551.nws You can download the program from there, post a help request, and then other guys can help you out.

      That being said, what is your fuel pressure? How long does the system hold pressure after key off?

        TPS is dead perfect along w fuel pressure. No fuel pressure loss to be concerned about after key off.
