Sorry mate but I'm getting frustrated. You started 5 topics - each one has now got theories from others in them with advice.
Listen to the post above re no power to fuel pump/s ^. That will certainly stop your car from running (Fuel, Oxygen, Spark)
It's nice to get advice and maybe there is a quick n easy fix you could do yourself. If you HAVE to DIY then create a list from obvious to not obvious and check it off.
To summarise the possible issues suggested in some of your threads in no particular order but if there is no fuel then START from there.
CAS + connection - Spark
Power to pump - Fuel, Cranks doesn't start
Fuel Relay - "
Fuel Pump - "
Fuel Filter - "
Fuel Reg - "
IC Piping - Pressure (AFM's)
Sparkplugs (fouled). Spark
Earthing - Spark
Coilpacks - Spark
Loom - Spark
Ignitor - Spark
AFM - AF Ratios
ECU - Management
02 (no!)
Then take it to a mechanic, please.
