O2 sensor has always been disconnected. My city mpg always been high, and yes smell of fuel always been there(little more than typical classic car)...could something that was going from all along reached its point...?
Its ok..i always try to figure this myself before handing the car to the pros....i am greatfull with the help that i received from all of you guys, that i have troubleshoot things i did not know before...now i know where the fv valve and o2 relay is haha....
My first 911, and aside from alternator rebuild really never had issues with it in 8-9 months of ownership...was getting a little bored...one should be carefull of own wishes
will try to update once figured out

BOJAN,
How many times have you mentioned that you felt it was fuel related. But you never once attempted to check it. If you don't have a fuel gauge to check for the fuel pressure, you could do the volumetric or flow rate check. Test the
FP and measure the amount of fuel coming out before the
FA (fuel accumulator). Do multiple measurements. If the flow rate is 1 liter+ per 30 sec., consider the
FP out of the equation.
An out of spec WUR will also give you starting problem too. So you need to know the control fuel pressures. Last but not the least, you have unmetered air going into the system. You may not know it but it's there. Unless you test and confirm the absence of a significant source of air leak, you are simply relying on quess-work troubleshooting. Stop quessing and you'll know and find out what's causing about this non-start scenario. You also could do visual inspection of all injectors including the
CSV. Keep us posted.
