po678 it says glow plug 8 contol circut , first diesel adventure which direction do i go?

anybody?

your #8 glow plug is bad, thats the one closest to the cab on the drivers side, just remove the wheel, the wheel liner and you should see some 8MM nuts with a wire attached to it, so just remove the nut, then use a 10mm socket to remove the GP, put some anti-seize on the threads on the new one when you put it in:tu:
