I have a problem with starting my 1991 2.5 turbo diesel motorhome
it turns over on turning the key but it won't start -wiring has been checked out -ok -could be the glowplug -it has only ONE!-does anyone know about these glowplugs? -been told it is a special one & could cost 75.00+!!-surely this is not right?
It had been starting fine until recently -only had a problem sometimes if we stopped on a journey for fuel & then it wouldn't start again until we waited 5-10 minutes then it would start first time -now we cannot get it started at all
can anyone help please ?

thanks BB4210

Doesn't sound like the glowplug, it's only usually needed to start from cold.
Any lights on on the dashboard?

Definitely not the plug in this weather, as you mention it not starting after fueling I'd check the fuel tank for sludge / varnish / water, check the tank strainer to see if its blocked, then check the fuel filter.

Are you sure its turning over fast enough. The starter and or battery may be getting tired too.
