Tdi Bad Starter

[Brookydave]

Hi there,

Just joined you lads today, as I have purchased today a very poor starting R reg Galaxy tdi. It will only start after a long tow, and doesn't seem to have any turbo oomph. I believe this all started after a cam belt change.

I will check the glow plugs and cam/diesel pump timing - Are Gates belts OK on Galaxy? - however my main question is:

There is a clear blueish section of pipe that leads to the fuel pump. There is an awful lot of air in this pipe even when running. Is this normal (doesn't seem correct). If abnormal any clues to its origin (replace fuel filter?)

Thanks in anticipation.

Interesting - my TDi 110 is also playing up shortly after a cambelt change - runs, but not properly. I'll keep an eye on this thread...

 

May help you to check out my TPS thread - contains a short yarn about my cambelt change - it coincided with problems with my immobiliser servo and EGR valve.

 

Good luck,

 

Matt

Update.

New battery. New glowplugs test OK for continuity. BUT no volts to heater rail + insulation removed from supply cables.... Some cowboy has beat me to it.

Need wiring diagram now. Presume fuse or relay or broken wire (which is why the water temp gauge does not work). Still rest of car in great nick, so chuffed.

I've been there. Try this simple routine and checks.

 

When warm, the voltage on the heater rail only exists for about a second or two at most. Down around freezing, the glow light and heater rail are active for several seconds.

 

A quick check, disconnect the coolant temperature sender - its behid some gubbinry on he front of the cylinder head near the gearbox and its a sod to get at. Do not be misled by the fact that the engine temperature gauge reads normal. There are two sensors in the package and it's the other one which the ECU uses for making decisions. A quick clue - does the engine fan always come on for a few mins after switching off, irrespective of temperature?.

 

When disconnecting this thing, you will possibly find that, like mine, the wiring is brittle and the earth connection breaks off. ( Also a sod to reconnect.) However, once connected, the glow plug feed and lamp are active for up to 15 seconds.

 

If the light comes on for a while and still now volts and yours in a 110hp unit, ther is a 60A fuse and some relays on a panel hidden behind the main fuseboard.

 

If you're chasing this, try to pick up on one of my topics, similar title, a month or so ago. Sorry can't be more help right now, gotta go - bushed - need sleep.

Thanks Scorpiorefugee.

The wire had gone brittle and broken off. Repaired wire and now have 10v on the glowplugs for about 8 secs.

Still wont start. nearly gets there, but what with lack of oomph, I think the diesel timing is out. Will wait for the manual before attempting that one.

Thanks again

Pleasure mate! :blink:

 

It took me a long time to get around to that one. Took all the damned fuse panel out and worked back from there. I assumed that, since the glow plug light came on, the circuit was live. (silly me!) I also assumed that, since the temperature gauge showed normal, the ECU knew that everything was OK(Silly me!!!)

 

Never mind. I'm glad that you're moving forwards.

 

It sounds like you have a fuel line problem also. I can't help you there but there are many who can and will. You may have to keep at it or start a new thread but the old Gal should be worth it in the end.

 

Good luck.

 

Ron.
