BLINGO bad starter

citronut · Post by **citronut** » 28 Jan 2010, 13:21

the van is a 1.9 NA D

a freind of mine has a blingo which is a s*d to start first thing but once started it will start every time even if left for a few hours,

fitted new glow plugs a few months ago, and also in the last month i fitted a ne filter houseing with primmer plundger,

as there was signs of fuel around the base of the plundger,

the glow plud light only stays on for a very few seconds like 2 or 3,

i got him to drop by my workshop the other day and lashed a test light up for him to borrow, but whilst he was there i placed the test light between the neg battery and the glow plug feed post on the end of the air box,

and even though the light on the dash went out nearly straight away the test lamp stayed on for almost a couple of minuites,

i asked him to repeat this the following mornning which he did, but still takes a lot of cranking over before it fires up,

i have asked him to try pumping the primmer up tommorow befor he trys to start it,

do these vans have an electric lift pump, or even a transponder type imobaliser,

we will see

I doubt they will have a lift pump in the tank, certainly not when theres a hand primer..

Has the front seal on the pump gone west? Not always detectable untill cam belt covers off, or theres a constant smell of diesel but no sign of any in the engine bay.. Cam belt obviously gets saturated aswell..

I would recommend checking the valve clearances.

If you haven't done already, replace the fuel line between the filter housing and the pump with a clear tube so you can check for air.
Also check the leakoff pipes to see if they're hard, if so, replace them as they can crack and let in air making it hard to start.

Glow plugs run for quite a while after the light on the dash goes out so what you've found is a good thing

Malcolm, I take it that the engine is a nice old fashioned diesel??

If so check that the wax stat is pulling the pump up a bit when cold, this can often go wrong and it's a bit like starting a Mini without using the choke.

Also it's only a very quick check to test the glow plugs again, just because they have been replaced does not mean that one cannot have failed again.

Sometimes the obvious passes us by without a thought.

Martin.

thanks Martin
i did/have re/teasted all the glow plugs again,

is there an easy way to find/trace an air leak,

also i did plug my DIS-LEXIA in but it could not find any ECU's at all,

unless im useing the wrong plug addapter???

Clear pipe is your friend when tracing air leaks.
Replace as much of the fuel line as you can so you can see bubbles.

I take it this the DW8 engine ? Depends how old it is whether it has an ECU or not, The later ones have a Lucas DCN2 ECU, Very basic though, just really for Timing,EGR & glow plug control. The ECU should be visible in the engine bay near the battery, dont think it would show up anything anyway.
It deffo does not have a lift pump in the tank.

Valve clearances!

citroenxm · Post by **citroenxm** » 29 Jan 2010, 22:34

If the XUD is ANYTHING at all to go buy then once valve clearences were set they VERY RARELY ever went out!

Im uncertain if the DW8 is bucket and shim or hydraulic adjustment.

Paul, I'm afraid I have to disagree; I have encountered on a good few occasions (two 205's and a BX, all naturally aspirated) XUD engines that have struggled to start in cold conditions due to closed up valve clearances. Usually they do not vary, but if the engine is permitted to overheat the valve clearances can close up, and often the only sign is difficult starting. As the DW8 engine shares much of the design of the XUD (including I believe solid valve buckets) I feel this should be investigated.

It's bucket & shims on the DW8.
The 1.5d engine in the saxo/AX is well known for the valve clearances going to tight & causing hot starting probs. Cant say ive heard of any probs with the DW8 though.
