Power not reaching glow plugs

Recommended Posts

Hi,

My TD4 (2003) won't start easily when cold.

I thought that it was the fuel pump, but a mechanic friend identified that the plugs won't working.

In fact all plugs were open circuit - so have been replaced.

However ... no change ... no power is reaching the plugs.

There is a timed click when turning to the middle ignition position ... but no glow plug (curly wire) icon appears on the dash, and the plugs don't heat.

The glow fuse is fine. Sooooo ... is this due to a duff glow relay? Or is there a circuit board that has packed up?

Any ideas?

(By the way, where is the glow relay located? I'll change it if I can reach it!)

Many thanks.

Hi,

Many cranks to start cold.

Several cranks when warm - sometimes many sometimes one or two.

I'm suspecting fuel draining away promptly after a stop, requiring a vacuum to pull it back.

Also the duff glow plug system won't help - I plan to overide that with a remote push button ... once i can work out where the glow relay is located! Any ideas on that location?

Thanks!
