hi all

i have now changed to a xsara hdi 90 so my wife can drive however in the mornings its a bit more difficult to start in the morning and is lumpy i took it to a garage and they tested the car advising me the glowplug relay needs replacing which i can get for £30 but does that sound right i only wonder as the engine was warm when i got there and wasnt sure if the relay would still come on when warm he said there was no power getting to the plugs but there was power going into the relay

Very easy to check the relay.....

Put a jump lead on the positive battery terminal and place the other end on a glow plug end...get someone to turn on the engine after waiting a few seconds, if it starts nicely the relay is faulty.

Another way is to place a thick wire/solid piece of metal across the terminals of the relay and get someone to start the engine, if it starts nicely the relay is faulty.

Be careful not to keep the wire/metal on there too long.

right changed all the glow plugs as they were all shot, checked relay turned the key when cold no reading at first new plug but 13.5 volts when cranking it over is this normal as i understand the plugs come on for smooth running when cold. i have also read that it could be some sort of temp sensor any ideas.

Are you sure your lift pump is running every time?

The glow plug behaviuor you describe is probably normal, (minimal preheat unless it's about -10 deg. or less, but energised during & for maybe 30 seconds after starting).

no its not that as its not a pump just a sender unit but keep reading about temp sensors which is making me think it could be that

Is your starter motor quick enough to get it started? Mines is slow & takes a longcrank to get her started
