Got sent to a P6000 today with E-28 flashing.
Disconnected battery for 5 min, no help
Did pedal dance... no help.
Going back tomorrow to check spark plugs (Thx swoop223).
I will be inspecting the wires also.

-the call was random no start with random dying.
The seat sensor was bypassed long time ago.
the dummy lights are lit for safetybelt and no one in seat.
operator says its been like that a long time.
Meethinks those dummys blinking may be why the pedal dance has no effect.
