Bongo Fury

Hi guys.

I have a 96 2.5 diesel. The engine has been running great however in the last few weeks it has been getting harder and harder to start but it’s turning over really well. I did some fault finding and established that all 4 glow plugs have failed, they are only 18 months old and done 5 maybe 6000 miles. Spare plugs popped in and starts first time as usual

First thought was the relay was stuck but the relay is good. I get voltage at the glow plugs until the engine gets up to running temp and then the voltage drops off. So I am assuming that the relay, Ecu and temp sensor is all good.

Looking at the glow plugs there is no visible pitting or damage.

Anyone have any suggestion to what the cause of all plugs failing at once could be.

Cheers

What make/model of glowplugs, there seems to be the usual discussion regarding quality when you buy cheap ?

If I remember correctly they where NGK not sure of the model got them direct from motor factors. I supplied the reg and they supplied ones of the correct length but I did notice that there over all length was longer than the ones I removed

Well NGK are usually considered a good make so probably not that problem then.
