OT- Diesel problems
Turbo Mini Forums

I’ve got a pug 106 1.5 diesel and it doesn’t like starting. It’s my workhorse really. The trouble is I know nothing about diesels. At first I thought it was just the freezing weather in the mornings but it won’t start even if it’s kind of warm. It’s had new glow plugs and they all read around 12v when there supposed to. After about 10 mins of flicking the coil light on and off and cranking it over a few times it usually starts.

I know some of you drive or know lots about diesels so any help would be great.

Cheers

The glow plugs reading 12v don't mean anything,You need to disconnect them and make sure they are all taking a current.My glowplugs usually only last a year.
Also Is the relay holding them on long enougth,mine stay on for about 30-40 seconds before you hear a clunk when it cuts out

Yes agree with Dangerous. Most conclusive way to test them is to remove them and then connect up 12v and earth to them. They should glow red hot within a couple of seconds. If they don't glow at all they are knackered, definately.
My diesel has a post heat function, where they stay on for a couple of minutes even with the engine running, not all diesels do this though.

Does it always start OK when it is warm? If so, this points to glowplugs even more. However if it won't start even when warm this points to more serious problems such as lack of compression.

You really need to check the current draw of the glow plugs...

you should see 30-80 amps for about 20 seconds.

If thats ok, I'd suspect compression and test it.

Other problems could be injection timing - does it run perfectly when warm? Is it slugish?

I just put the battery charger on each plug seperate,still in engine(with the links removed)take about 6 amps each

How old is the fuel filter ?

Have you emptied the water trap under the filter ?

Also try pumping some fuel up manually using the little push button on the pump--as if you have a air leak the fuel will run back down towards the tank

Cheers guys. Right well i took all the plugs out-connected them all to earth and they glow red hot. (infact i started melting the rocker cover,oops). When it's warm it starts fine. Also runs fine. I havent got a diesel compression tester.
The only other thing i get when it starts is a load of diesel smoke. It's kinda white/blue not oil tho. I got 2 of the injectors recond a little while back i think i may get the other 2 done.

I guessed....

On the last diesel I measured myself it was 90 amps... but it was a common rail and 6 cylinders

lol, thanks for that info Tom.
Right....When i give the manual fuel pump a few squeez's it goes solid. 5 mins later it's kinda soft again, I'm sure i can hear air when i squeeze. Can't find any fuel leeks tho or see any air bubbles in the clear fuel lines. If there is a leek it must be after the manual pump e.g.filter/pump/injectors. I'm gonna stick at it

the glow plugs take 8 amps a piece!

having listened to the above, i would like to add......

that if the car runs fine when started for a few mins & warmed up

i can Assure you the slippage hose or hoses which go to the injectors, the ones that loop over to one another are perished

the hose or hoses drawing air under vacuum when the car is stood especially over night!

you only need one hose split or perished "SLIGHTLEY" or jelly like on the end, then you have the symptoms you describe.

usually you can see a "SLIGHT" weep from the pipe or pipes

Replacing these is not expensive!
you can get this pipe on a roll from you local parts supplier for a few quid rather than pay a fortune out at the dealers.

my advice is change the whole lot (end of problem)

keep us informed.

When I googled it,A problem using non peagout fuel filters was mentioned ,as the non genuine ones let the fuel flow back to the tank

Metro turbo weekend driver,Mini turbo in the making again!

Sounds worth some further investigation to me. good find Bri.

Are the pipes your talking about the ones that go from one injector to the next then back to the tank? I've just wiggled one and can deffo hear air. If i'm gonna order some of this stuff...has it got a technical name?? Slippage??

This may also sound daft but it might be your fuel filter and where you park.

Genuine Peugeot filters do not allow fuel to 'run back' after you switch off whereas the replacement ones do. They then take ages to pump the fuel through. If you park on a hill then it obviously helps because the fuel does not run as much.

Well i've just fitted new 'leak off' pipes. (£3.50 a meter :) ). I can see why an after market filter would cause a problem. I'll try and order one.
Thanks Load for the help guys.
See how it starts tomorrow morning i guess.

about the none gen filters i know the MAN german filters are shite as they do their job too well and block up Quickley.

i have been there.

I have tried the lot of none gen ones,

there is some crap out there

Who would have thought it. It started first time.
