Hi,

Currently in Africa, had a very cold night (-10) and this morning van will not start. Turns over fine, but there is a very loud buzzing from the fuel tank area - presumably the pump or perhaps the filter?

Maybe we've used some dirty diesel and the filter is blocked or maybe the pump is dead?

Can anyone offer any advice?

Thanks

Hi
Not sure of the situation in Africa but here in Australia in certain places during winter they change the Diesel fuel delivered to the colder parts of the country because in winter with the "normal summer diesel fuel" the waxes in the fuel solidify, thus blocking the filters as well as being very hard to pump through the fuel system. I have experienced this years ago although in my case it actually started then, went a few blocks & stopped. Then when the temperature rose sufficiently the wax would melt & it would then eventually
start again. In my case it never got to -10 as you have said, it was around 0 to -2 c. Maybe you have some "summer fuel" & are now suffering from the same problem?
Cheers

Yes.

Sounds like the diesel has gone waxy, and is gumming up the lift pump.

Let it warm up, and hopefully it'll recover with no damage.
