Glowplugs Light

[jdomingos]

Hi.

This is my first post and i would like to thanks in advance the help you may provide.

I have a Galaxy 1.9TDI auto 110bhp Xreg (2000)mk1. Some times the glowplug light on dashboard don't came on and the car not start. Most recently (today) when i was turning the key to start the engine lights on dashboard on, but no starter. switch off key, switch on again and nothing again. 3rd time and was ok. car started. Some times glowplug light don't show on and i have starter but don't start but another times i have glowplug light on but no starter. Can anyone give some advice please. Thanks
