hi i need help i have a mk vrs octavia it was running smooth and boosted strong on my way to work then after 4 hours I was going to a meeting and it wouldnt start I have tried bum and jump start and new battery as i thought it was dead 

still nothing the petrol pump is working and there is petrol in it the coils look ok could be cleaner i guess and not seen the spark plugs as dont have the tool to get them out am now at a loss can any one help please 

thanks 

think it may be fuel pressure regulator 

I would be inclined to check the fuse to the fuel pump relay, and the relay itself.

 

Is the yellow key symbol lit up on the dash at all?.
