412d wont start

[412d]

Hi

My 412d has decided to play up. It will start fine normally in the mornings. When it is stopped once warm and i try to restart the heater plug light fails to illuminate and van wont start. If it is left for variying amounts of time, some times 15 mins other times 6 hrs+, the glow plug light comes on and it will start.

Any ideas??

I am not very good on diesels, but this points to the glowplug control unit, the life of these things is limited by the heavy currents involved.

I have opened the control box to find microchips ect and a large relay. Even by holding this relay shut (current is passing through because can see arc as terminal touch) it fails to start.

Does anyone know if the the ecu sends a signal to heater plugs? Is the problem ecu related and more than just the heater plugs not working?

Don't know a huge amount about diagnosing faults, (i usualy work on the eliminaton process ) but your van doesn't need the glow plugs to start it when its already warm, should kick in right away.

My 308 cdi had a problem with warm starting (but the glow plug light was ok). It would fire up not bad from cold but from hot it would wind up for ages before cracking into life. The problem was a faulty injector. My fuel injection specialist told me that these 2150cc engines were prone to this fault from 02 - 03 plates.

Sounds like an injector to me too. Probably only one, as any more and it would probably not start at all. To eliminate which one it is you need a set of spill ports, which measures how much fuel is going to each injector.

Carry a can of aero start (sniff) in will start on that but only use SMALL amounts and only as a last resort.
