I can hear what sounds like relays clicking from under the bed of the
truck, but I couldn't actually hear the pump humming as I expected.
I didn't change the pick up myself so I don't know... and yeah the
timing belt covers were in place... the engine sounded weird to me when
it was cranking over... almost as if there was no compression... I
chalked it up to not knowing what a 4 cyl Dak sounded like when it
cranked over... if the timing belt went bad and the cam wasnt opening
and closing the valves, then that would cause the sound I heard. It
sounded just like Christines engine spinning over with the plugs out...
I'll go back and check things out...
