#1: GTI wont start. Author: LeeThr, Location: North West WalesPosted: Tue Apr 05, 2011 5:46 pm ---- Right, friend of mine bought a 2000 plate 206 GTI on sunday. Seemed fine, another friend of mine was selling and has been faultless for the past 4 weeks ive known it started first time everytime. Coming back from work today the car just cut out completly on him. Got it towed back to his. Now the engine just turns over on the starter fine, but it just will not fire. Checked every fuse about half a dozen times, one had blown but changed it hasnt blown since. Read the ECU for fault codes and nothing. When you try and start it just turns and eventually the K light starts flashing. Checked fuel rail, plenty of fuel getting there. Clean as anything as well. Oil seems fine. The digital heater controll however has gone out and wont come back on at all as well. Only thing we can find is a 2 pin plug that is coverd in oil dangling from a group of a few others behind the rad next to the oil filter. However cant see anywhere for it to go to within reach. Spark plugs where changed last week. Central locking and alarm still seems to work.
Anybody have any ideas what to try next?

#3: Re: GTI wont start. Author: Seabook, Posted: Tue Apr 05, 2011 6:14 pm ---- but he has check the fuel rail and there is fuel over there, so don't think is the immobiliser because i think it work on the fuel pump isn't it?
#4: Re: GTI wont start. Author: LeeThr, Location: North West WalesPosted: Tue Apr 05, 2011 6:16 pm ---- Not too sure how to check the coil pack. Any advice?
Also what can be done about the immobiliser.
Also forgot to mention on the end of the engine that meets the gearbox there is a strong smell of something burning.
#5: Re: GTI wont start. Author: leigh_boy, Location: EastbournePosted: Wed Apr 06, 2011 1:00 am ---- to many things to list most common i can think of is
coil pack
crank shaft sensor loose or faulty
no fuel getting to plugs.
if you open the bonnet there is a big RED button at the back on the right hand side press it and try starting it again.

Good suggestion. Did he go over a pothole just before it cut out by any chance?

Allready tried the fuel cut off switch a million and one times, even tried turning over with someone pressing the switch as well, no difference.

#9: Re: GTI wont start. Author: orangeGTI, Location: whitbyPosted: Wed Apr 06, 2011 3:58 am ---- our car did this just stoped while driving round town. turned out that the fuel pump was f****d. was still geting fuel to the rail just wasn't injecting enough fuel

Yep, tried this allready.
#11: Re: GTI wont start. Author: LeeThr, Location: North West WalesPosted: Wed Apr 06, 2011 10:31 am ---- anybody got any ideas as to why the digital heater control has gone off? Checked every fuse about 10 times, this went the same time the car cut out. Does this run off a fuse? Only thing i can think of is if its a relay?

You have checked the fuses in BOTH the fuse boxes?
1 fuse box under the bonnet & another 1 in the passenger cabin.

Yes checked both fuse boxes, swapped relays around as well. No difference.
Pulled the fuel pipe going to the rail off tonight and placed it in a transparent container. When you turn the key to the second position (one after accessories) You can hear the fuel pump priming and you get a few dribbles of fuel through. When you try and crank the engine, nothing comes through at all. It's not long had a new fuel filter so, pump gone?

looks like immobilizer fault to me
#16: Re: GTI wont start. Author: LeeThr, Location: North West WalesPosted: Wed Apr 06, 2011 4:40 pm ---- How do you cure the immobilizer?
#17: Re: GTI wont start. Author: punk, Location: BrumPosted: Fri Apr 08, 2011 6:44 pm ---- If it is the immobiliser shouldn't the display read immobiliser fault

The display's a bit dodgey and doesnt work.
#19: Re: GTI wont start. Author: AX-Rated, Location: Swansea, WalesPosted: Sat Apr 09, 2011 3:19 am ---- My guess is that 2 pin connector goes to the crankshaft sensor.
If the ECU doesn't see this signal, it wont send thee firing signals to the Spark plugs or the injectors.
The sensor is close to the oil filter and sometimes wont give out fault codes if its defective/not plugged in.

Would this stop the fuel pump from priming as well?
#21: Re: GTI wont start. Author: leigh_boy, Location: EastbournePosted: Sat Apr 09, 2011 1:47 pm ---- if the fuel pump is not priming there is a relay that controlls lots of different things big black 1 under the ecu its about £40 for pug or u could get 1 from a breakers and will probabbly fix the fault.
#22: Re: GTI wont start. Author: Edward, Location: In the garagePosted: Sat Apr 09, 2011 2:40 pm ---- The big relay is about £15.
#23: Re: GTI wont start. Author: LeeThr, Location: North West WalesPosted: Sun Apr 10, 2011 12:48 pm ---- Does the big relay control the digital heater control as well?
i bought 1 about 2 years ago now becuae mine packed up and im sure i paid about 35 / 40 from pug, then again might be talking about something different.
Does the big relay control the digital heater control as well?
The heaters only blow when the engine is running, but they cam be adjusted without the engine running.
The crankshaft sensor wouldn't affect fuel pump priming.

I know they only run with the engine running, I mean the whole control unit has gone dead so you cant adjust it. Im asking if its that big relay that controls that as well?
