Ok, so upon replacing the fuel pressure regulator yesterday, the car fired up no problems after refusing to start and cutting out etc.
Must have stopped and started it a dozen times over two days no problems at home just to check...then drove to the shop, came out, and....it would not start.
I assume the fuel pump has packed up as there's plenty of battery power and it wouldn't start trying to bump it.
Although...I got towed home, and there was a colossal oil leak over the driveway, it's coming from the engine bay somewhere (it was dark and couldn't see where from)
So I may have two unrelated problems or one big one!
Any ideas?
Cheers

when my fuel pump started to fail i got by for a couple of weeks by whacking the fuel pump cover under the rear seat bench with a baeball bat, seemed to kick the fuel pump in the action.

try giving it a whack before trying to start the car or a whack while cranking, obviously only a temporary fix but if it works you know its a faulty fuel pump

Cheers guys, and it's a 1988 325 mate

Cheers for the info!
