sorry, my machanic used a different name than hall i forget what he said i would know it if i heard it. SO the "hall sensor" sends a signal to the ecu which then sends a signal to the relay to turn on the pump. That's the procedure. What does that power box do? My machanic told me that if you do the test and don't get a spark it could be the power box above the battery.

mind you it would have taken the techy at a shop hours before the problem was fix my machanic found the problem in 3 min's over the phone and by using that "test" it is a much more effiecent usage of time than what the faq's.
