glow plugs on GQ

this happened a couple of years ago but the problem went away. It's more common now but maybe 1 in every 5 starts so is getting worse.

Last time I did look at the box inside the car but hard to fault find because I wasn't sure if it was 'broken' at that moment. I'll replace the box next to the battery and see what happens.

Thanks for the feedback.

I understand the control unit can be problematic. You might pick one up from the wreckers. Not to discount the relay but my money would be on the control unit if I had to guess. my son connected a switch to the input to the relay, effectively bypassing the control unit. He would hit the switch for a couple of seconds and then fire it up. Worked great.

finally the control unit takes an input from the temperature sensor so don't discount that connection.

cheers

excellent info. Thanks for that.
