Finally getting time to work on some of the cars and reclaim my driveway. M-Sport 318ci sold after a quick swap out of the fuel pump. Sod's law, next car in line won't fire, suspect it's a similar issue.

Swapped out pump, swapped out relay. No fire, fuel pump not priming. Cranking registering on rev counter, easy start allows it to fire briefly. What's next...?! It's a 316i E46 btw.

Cheers in advance
