went through rather large bog hole, and about 10 mins later down the track the sub tank gauge had dropped to empty, and the sub tank light is on solid. Confirming that the tank had not been punctured (filled it up at the next servo)
I have read the repair manual and have tried the "sub fuel tank diagnosis system" but have been unable to to get it in diagnosis mode to find problem.
Things I have checked in sub tank unit:
Pump sender unit has resistance (roughly 5 ohms)
Pins on both plugs have good earths
Anyone with some experience in this matter please come to my rescue!!!!!!!!!!!
