Hi, I've found two older posts about this, but the links in one of the posts don't work and just want to check the solution before splashing out.

Symptoms:
Car worked fine then suddenly wouldn't start.
No glow plug light on ignition - car turns over fine but doesn't start....

I would just like to warn others about buying cheap glow plugs....
I bought some glow plugs from eBay just as part of routine service and then had problems starting. Knowing that I had new plugs and 10.5v at the buzz bar I went through a nightmare of trying to find what was causing the slow start...
