Bongo Fury

difficult to start first thing,ok the rest of the day new glo plugs fitted at last service, so I suspect the relay or a blown fuse, Question is where is the relay and where is the relevant fuse located. any help most welcome

You could still have had a dodgey glo plug fitted from new. You can test them all to check there status.

Relay inside drivers wing behind the battery, fusible link on th wire from the battery. Check the connections are all tight & glow plug rail isn't shorting anywhere, especially if shorter plugs've been fitted where ther were longer ones. Were the new plugs decent onesieNGK, or were they cheap & cheerful(or not)? Check there's 12 v getting to the rail & that the battery has enough beans to turn the starter as well as power the glow plugs. Worth waiting 5 seconds after the glow plug light has gone out before turning it over to see if it makes a difference?

Why blame the glo plugs? It is possible that fuel is not present which would mean air weeping into the system somewhere. Have a look at the flexible fuel return pipe which is between no 2 injector and the fuel pump, particularly if you have an older Bongo.

Additional. Does the Glow plug light on the dash come on? Can you hear the relay dropping in and out? As its OK after the first start I would suspect fuel starvation, is there any smoke if so what colour?

The glowplug "light" on the dash has nothing to do with the glow plug circuit...it is simply a bulb/timer and if it didn't come on at all "blown bulb" the plugs would be unaffected.

Murphy's law arrived today, it started first time. anyway the plug light comes on ok, no smoke of any kind, spoke to the mechanic who serviced it, told him the problem,he seems to think its the fuel draining back, as in this weather,it should start without glo plugs. What's anyone else think?

Why bother fitting it then?

To remind you to wait before starting.......

You may or may not know that on a Bongo the glow plugs do not go out when the "dash light" goes out....as they are in no way interconnected......in fact..the glow plugs stay on untill a certain amount of revs are acheived and a certain temp reached....this can result in the glow plugs switching on/off/on/off several times before finally going off permanantly....this is one reason the plugs seem to need regular replacement and are short lived.....you can tap into one of the relay input wires and fit a illuminated switch to manually overide this and you will see the switch light come on/off/on/off as the plugs cycle (factsheet in members area)
