Weird no start issue - runs briefly with fuel pump fuse out

I have a no start issue with my '86 Carrera. Engine turns over fine. Swapped DMEs and no change. I can smell fuel so I check for spark next. I removed the fuel pump fuse and pull one of the plugs and ground it. Then turn the engine over and it runs for about 10 seconds until I presume there is no fuel left in the lines. Weird.

I plug the fuse back in and no start. So I decide to remove the fuel pump fuse again and crank it. Lo and behold it runs again for a few seconds. I feel the answer is simple but I can't see what problem is causing this.

Any help greatly appreciated.
