Finally had some time to look at the camper again this morning.
Fitted the new distributor (I followed this video https://www.youtube.com/watch?v=KkyBAMMHpa4
), and coil connected everything up and the engine will turn over and the fuel pump buzzes on and off whilst cranking the engine, but it doesn't fire up.
tried many times now, checked and double checked the connections swapped between the two different fuel pump safety relays but no joy.
Also getting massive backfire occasionally when cranking the engine and smaller popping sounds but not firing up.
I checked each spark plug against the block while cranking the engine and they all spark. when checking number 2 there was a huge back fire though. I'm getting a pulsing (although quite faint) from the test lamp out of terminal 31b of the relay when cranking.
Any ideas? Could the engine be shot? the coil wrong? (although i got the one that was meant to match the distributor according to the simon bbc ebay info) Carbs blocked? not sure where to go from here
