1996 peugeot 2.5 Di - No glow plug light - LDV CONVOY - mike mc d

After having my ignition switch replaced - wires soldered - i have been intermittingly having my glow plug light not come on when trying to start my engine

I did replace the plugs as one was shot - (went to start it no light) started with wire from battery to plug for a few seconds - a day or so later light had come back on by itself , ran sweet as for a few months , then once again no light

Breakdown started with easy start - once gain a day or so later came back on it's own ran ok for months - today breakdown comes out , started eventually with some easy start

( I want it fixing properly) told easy start is bad news

The thing is is am suspecting that it might be a wiring fault as i lost my speedo after the ignition was wired in - the needle use to bounce - no trip meter and no milage being clocked up - after a few weeks my trip meter and milage started to work intermittenly again

So i am unsure what it could be - ie simple as just a broken wire or a relay has failed

It has the EN55 i believe as is the non turbo if that helps - can anyone suggest anything

I do have a test meter but never used one before as not sure what settings to put it on - sorry if sound a bit thick but just started to do my own mechanics - not to bad with them as managed to change the clutch cable the other day - is a good van , has not given me much greif except this slight problem crops up once in a while

Cheers mike

A Diesel engine is a compression ignition engine. For it to start it needs to be mechanically sound so that the intake air is compressed to a ratio of around 20:1 and in so doing the compressed and turbulent air is heated to around 500 degrees Celsius. Fuel oil then must be injected in the form of a high pressure very fine spray at the right time onto the hot compressed air. If your engine doesn't start then essentially it wil be for one of these reasons.

Indirect injection diesels require glow plugs for preheating because air is compressed into a seperate swirl chamber onto which fuel is injected. The compressed air tends not to reach sufficient temperature when the engine is cold.

In the case of direct injection diesels air is compressed and fuel is injected directly on top of the piston and glow plugs are generally not required unless the outside air is very cold.
