306 D Turbo Glow plug problem

The pale (white) smoke is unburned fuel. Test for current at the glowplugs. On that engine if they're not heating up it's amazing it starts at all. DaveK.

Thanks,

Current to the glow plugs is fine 50% of the time & the car will start & then run without any problems. Its when the dashboard light does not come on that baffles me. When this happens, the plugs do not heat up & the engine will not start at all. I have no idea what the root of the problem is.

When it works, I can actually hear the relay (behind the battery & when I have the bonnet open) click on when the glow plug light switches on & off again when it goes out after a few seconds. Then the car will start. On the occasions that it does't start, there is no activity from the relay whatsoever. As mentioned before, I have changed the relay but the intermittant problem remains.

I tested the plugs when the engine was replaced & they were all fine. I think they were all new but the unburnt fuel does suggest that at least one is faulty.

Any Ideas?

Electrics baffle me.

AAARGHH!

I took the car to a 'specialist' yesterday & he found no faults whatsoever despite checking Glow Plugs, Relays..... everything. The problem still persists though.

Has anyone even heard of this intermittant problem before? It seems to be unique to my car.

Ah yes. That's a very good idea. I'll have to wait till Saturday to check it out but I'll check & clean all the contacts involved.

Thanks, JG.
