Over the last week I've had issues getting my car started. Its a 2004 320D tourer on 154000 miles.
When you turn the ignition to position 2 the Engine Warning/MIL light doesn't come on, neither does the oil pressure light and the temperature gauge goes all the way into the red and there is no sound from fuel pump. It will crank fine like this but show no signs of firing. I can get it to start eventually by turning ignition on and off until all lights etc come on the dash as normal, you can then hear the fuel pump working but takes a long time to build pressure - around 13 seconds. It will then fire up and run normally. After a reasonable legth drive (50 miles to work) it will restart no problem, fuel pressure builds in 5 seconds and pump sounds much stronger.

After reading various threads with similar issues I've replaced the fuel pump relay and this made no difference, I'm not inclined to spend £170 or so on a pump just yet as people who have gone this route seem to continue to have problems and I get the feeling its more of an electrical issue i.e. signal to/from ecu or instrument pack etc.

Has anyone found the root cause of this issue?

Thanks in advance.
