Check the heater plug temp sensor is operating correctly

Thanks for the reply, would the heater plug sensor still operate when the engine is hot and the glow plug light is,nt showing on the dash?

Put a 600 ohm resistor in series with the glow plug temperature sender. This should give about 4 seconds glow with a hot engine, and a bit longer glow at lower temps, depending of course on exactly which sender you have fitted. Trial and error....more ohms gets you longer glow.
