[QUOTE="Marky Dissod, post: 28492, member: 13218"] I change the fuel filter annually, so that's unlikely but possible. What else ... Which makes me wonder about the electrical 'command gates' that would 'tell the fuel pump to shut down'. In other words, is my fuel pump receiving a lie that causes it to think I'm no longer driving on the highway @ 70MpH, and that it's time to shut down, so that I can unintentionally cause a traffic snarl and get thousands of stinkeyes? '02 L59 is physical cable throttle telling the pcm (not electrical wire throttle that the pcm can disagree with). I know, I agree, others reading this thread deserve to be reminded of what ought to be obvious ... Recently loaned the no-spark shot filled mallet that I'd been carrying for years to a good friend who has thanked me, but not mentioned it since ... Does that mean, 'maybe not just a pump, but a new tank'? or, 'new pump, and clean the ever-lovin schidt out of the tank before remounting it'? Doesn't this effectively mean, 'new fuel pump' anyway? So stipulated. [/QUOTE]
