Re: Aftermarket fuel system heater.
how do you know the glow plugs are working??? if you are going by the Wait To Start light in the dash, that is just an idiot light that will come on whether the glow plugs are working or not.
i put a small light bulb or led in the dash connected to the output of the glow plug relay to see if the relay is working or not. the WTS in the dash comes on for around 15 seconds and then goes out. the led will stay lit for up to 3 minutes depending on outside temperature showing power is going to the glow plugs.
mt bet is your glow plug relay has failed and the glow plugs are not working.

If you want the moral high ground, make sure you're not standing on a hill of horsecrap.
