I have a strange thing that happens with my glow plug indicator light. My light functions normally the first attempt at starting the car.
If the car does not fire, my glow plug light flashes while glowing on subsequent attempts.
I know that a flashing glow plug light before the engine is running means that I have a defective 80 amps fuse, or power relay. That would mean that the electronic system is not getting current from terminal 30.
EXCEPT, my glow plugs are sizzling away just like if the light were solid. The flashing light goes out, and the glow plugs continue to glow until the timer shuts them off. Why am I getting a flashing light when everything seems to be functioning normally??
