Can anybody give me an idea as to why my 1999 3.0 D is suddenly difficult to start? It's not a regularly used vehicle and it can be 2 to 3 weeks between use and in the past year it's covered very few miles. However it's always been reasonably good to start, sometimes taking a bit of cranking for first-time then it started later in the day fires up quickly.

In the last couple of days it has been very difficult to start, a lot of cranking and obvious smoke/vapour coming from the exhaust but still no firing. I'm making sure the glow plug light goes out and indeed leaving it a bit of extra time (maybe that doesn't help?)

The batteries are in full charge so it's cranking quite quickly but it is difficult, it has been quite a bit colder in the last few days so this may be affecting it I suppose.. Once the engine is warm it seems a lot better.

I'm wondering if the glow plug light goes out that set me know actually working or could that be the issue?

Any advice gratefully received

id see if you can get the glow plugs out and test them to see if they are actually working, the glows stay on for 3 mins i think after the engine has started to help condition the burn in the cylinder

Thanks Eithan, you are a true star on this site! Is doing a resistance test with a mustimeter  good enough? also could the famous oil rail pressure valve give the same issues/symptoms?

Thanks again

John

Hi, grab the power supply for the glow plugs with ampere clamps. At initial heating, it should read about 46 amps.
Greetings
