Zero compression

Left bank has 0,60,0 psi. Did not change after
adding 2 oz. Of oil and cranking again w/fuel and
ignition off. Have not tested right bank yet.  Car
has not started in a year. Had alot of gas in
crankcase. Changed oil an filter, fuel pressure
regulator. Bench tested and cleaned fuel injectors.
All work fine. New valve cover gasket. No oil in
coolant or vice versa. Heavy gas smell out tailpipe
when fuel is on and cranking motor but still not
starting. What do you think is the problem ? Thank
you in advance.
