I had problems with the fuel pump not working at all so took it out and it was a proper mess. I replaced it with a new one which primed as soon as I turned the key which was awesome and it meant I didn’t have to deal with chasing down electrical gremlins. I just need a fuel level sender for it now . Sadly though it still doesn’t start, turns over but doesn’t even try and fire. The timing marks are all lined up and I’ve got a spark so will have to do some more fiddling about to see what’s up.
