Odd Starting Behaviour

[marinabrid]

hi all

galaxy 1.9tdi mk 1 afn code, if i go to start after overnight, the car usually fires up quickly, today i had to move the car about 10 yards up the road, from cold it started up as normal, then a few hours later i went to go out, it just cranked and cranked for a very very long time, it did start up and off i went.

 

this has happend before, if i start from cold and go for a drive then i dont have a problem starting form cold again, just if i rstart and then run the engine for only a few seconds do i get this problem, could it be fuel running back, is there a soenoid fitted to stop this ?

 

ive had this problem before the car always starts in the end but takes loads of turning over.

it has anew battery and a new bosch starter and glow plugs, although these turn it over much faster it still dont cure the problem, there is nothing showing on the vagcom fault codes.

 

there dont seem to be air in the clear fuel pipe, no leaks just odd starting.

has no one else ever had this kind of problem with a afn 110 engine ?

When was the fuel filter changed?

 

Do you use bio diesel?

 

I would check the feed to the stop solenoid

 

Could be another case of dodgy connections to the relay/fuse panel or a dodgy relay.

i was wondering about that but where is the stop solenoid fitted and how do i check it ? have done all the filter relays etc checks and replaced ,every so called professional i known over the years have no idea at all,

Hi there

It's on the fuel injection see photo if I can upload it.

thanks for that pic, so if the solenoid is not getting a live supply does it shut off the fuel ? is that the way i test it, ?

or how do i test it for a fault ?

thanks

Yes you should have power to it all the time ignition is on, if you listen carefully you should hear it click as key is turned on, this could possibly be interrupted by the immobilizer.

shut off sems fine,i had to move car other day was only running about 30 secs, left it overnight, what a sod to start cranked for around 40 secs but as usual fired up and runs no problem,

 

then next day started perfect from cold , there must be some great brain out there to help with this, ive asked the same question a few times over a couple of years in the hope a new member may shed light onto this odd starting..

anyone ????

So did you check the voltage on the stop solenoid? if this car has a manual gearbox you can try this, remove wire from stop solenoid remove solenoid, remove plunger and spring, refit solenoid.

Engine will start, you will now have too stall the engine to stop it.

If car now starts OK every time you know you either have a dodgy solenoid or supply voltage fault. Do not try this with auto box

Thanks for that, would the stop solenoid not show up as a fault code if it was causing the problem ?
