Fuel problems urge

G'day I'm new here but I have a problem with my 2001 e46 325ci manual

I recently have been having hard starts in my e46 so I change my fuel pump and it didn't want to start. Just cranked and then flooded cylinder 6. I changed injector 6 as it was leaking (I cranked the car without spark plugs in to get the fuel out).
I also change my spark plugs and oiled up the cylinders before putting them in.Got the car to idle but discovered fuel being pumped into the intake hose from the throttle body and the hose that comes into the pipe between the air filter and throttle body.
I can get the car to start and idle but it's just pumping fuel into the intake pipe and then stalls out.
It's my only mode of transport so any help would be greatly appricated.
Thank you

The fuel pressure regulator is bad.

Replace the Fuel Pressure Regulator, the diaphragm has a hole in it. The FPR may be part of the fuel filter. Fuel is leaking from the throttle body because it ran down the intake boots.

Replace the FPR.
