Default 06 Mini Cooper s problems help

So Monday my mini was running great, pulled into the gas station (didn’t get gas) and started to leave. Car started up fine but As I pulled away from the pump my car started to misfire. I pulled it aside and ran codes. Pulled the code for limp mode and a misfire in cylinder three. I assumed maybe a spark plug so I swapped 3 to 4. Cleared codes and started the car again. With my luck, it started misfiring again. I ran code and it came up with p0300 (random multiple cylinder misfire) and p0313 (misfire with low fuel detected). So I’m the parking lot I replaced plugs, coil pack, incectors, and fuel rail. Yet gain, no luck. Any ideas? Anything helps. Motor cranks over while throttling gas, it has a really hard start, and it just stumbles the whole time running. I drive it home two blocks and it ran like crap the whole time.

Check fuel pressure? Perhaps a clogged filter/pump going out?
