I got the parts today

R&R'd the combo relay (fuel pump,etc.) and replaced the fuel pressure regulator.

Took me a few minutes to figure out how the regulator comes out - but once I did it was easy.

Make sure you have something to compress one of these spring/ring/clip type of things - I used a pair of pliers but it was not too easy.



The fuel Pressure Regulator that was in there was a Mercedes unit and the replacement is a Bosch unit rated at 3.8bar.

Could that be it? I HOPE!

I started it cold twice and fired up perfectly and warm three times and all 3 times, it started without any drama.

If anybody knows any other things I should look at that don't cost too much - feel free to suggest.

Thanks again everyone
