Golf III TDi, Starting Problem

[Joe911]

Hi,

I have problems with my Golf TDi, 1997. It takes too much time to start. I have run diagonostic test and found that glow plug relay needs to be changed. I did changed it but still the problem is there. All glow plugs were checked and fine. It takes time everytime i start it. I have changed all fuel filters etc. When i try push start it doesnt take too much time and starts stright away. I changed its cam belt two months before and probably that can be the reason... or i need to run diagonistic again after changing glow plug relay to remove the error from ECU.. if anybody knows please help thanks

If the battery is less than 100% you may not have enough power for the glow plugs and the starter.

Thanks Neil, I have checked the battery, it is 100 % but problem is still there.....

Have you checked the main engine earth strap? A poor earth will mean the starter turns more slowly than it should.

If you have recently changed the cambelt, i would recheck the static injection timing with vagcom or similar, as it could have changed slightly.

Other than this, temp sensors or fuel pump.

Thanks for your replies, The engine turns in normal speed when i try to start but i get starts after six seven seconds normally it has to start within two three seconds even if the engine is warm. The earth and battery things are fine. the starter motor is running fine as well. there is no smoke and when car get start it runs very good........ please any one have any suggestion to solve this starting problem........ thanks

I would say most probably timing or air in the fuel.

Also try disconnecting the 4 pin temp sensor, and see if it fires up straight away.
