My 1999 vw 1.9 sdi will not start there is no glow plug light any more. checked ALL the fuses replaced the glow plug relay. Still no luck. Hot wired the fuel pumps directly from the battery and got the car started straight away, but when it runs, the glow pug light flashes. Any idea why the car will not start?
The glow plug are used to heat the fuel on start up only, as a diesel uses compression instead of a spark (from the spark plug) have you try checking the connection on the glow plug, or changing the glow plugs themselves?

Check the glow plug thermo sensor...found in the cylinder head.
Unlightly anything wrong with injector pump.
Good luck

If the relay is not getting ground signal to turn on then it sounds like a problem with the ECU this is fed from there. Commonly dry solder joints inside the ECU can cause this problem, they have a tendency to crack around the transistors and heavier load components and also components that are subject to mechanical vibration. He said that the fuel pump relay is located in the kick panel and the ECU is next to this. Id take out the ECU and remove the main circuit board and examine for dry solder joints. If you don't know what they look like its somthing like this http://www.tegger.com/hondafaq/mainrelayoperation/dry-joint_small.jpg
Hope this helps
