We have a Nissan Elgrand 1st Gen E50 3.2 diesel. About 6 weeks ago it would not start in the morning, try after try. After about 2 hours it started and was fine for about 3 days. Then the same thing happened all over again. Once we managed to get it started it would be fine all day. We have had the fuel, oil and air filters and the glow plugs changed but now it's worse than ever. It won't start atall. The battery and alternator are good. Any ideas? Please help!!
Many thanks

The wire to feed the glow plugs will be corroded and needs to be made into a new clean connection ,mine was like this and failed to start even when warm but since I have done this its fine, The wire is located on the glow plug bar right at the back with a black screw on top a little tricky to get at so i took mine off that and put it on the front one for easier access and to keep an eye on it.

You should try and get the Glow Plug relay checked. Don't just buy one as they are not cheap. One method you might try is hooking up an old glow plug to the 'plug' power supply and see if it gets hot. Failing that an auto electrician!
