Okay changed the filter on my car. It was then running fine for a bit then started to die, got it into the garage and now it won't start. The batter was dead before so I had to jump it, now I am charging it.

I believe I need to bleed out the system. Fuel came out immediately. Car still wouldn't start. It will only fire occasionally then die instantly. Now, is there valve located somewhere in the engine area?

Test the fuel pressure at the fuel rail... it should be 5bar I believe at idle and 5.5bar under load. If there is insufficient pressure, I believe it will through a cE light.

Quick Question?

How do I test the pressure at the rail? There isn't exactly a port is there?

You need to check to make sure you connected the lines to filter correctly and didn't interchange the return line with main line.
