S2 Still won't fire on cylinder 4
Discussion
Hi all, been dipping in and out sorting various recommissioning issues on my 2.9 but 2 elude me - brake master and slave and the lack of spark on cylinder 4.
It seems to be only cylinder 4 that won't fire. The plug is wet so has fuel. I have ground a plug to the block and still no spark (sometimes I get an intermittent spark but thats rare). I have swapped leads and I think it may be a dodgy plug suppression extender but not 100%.
I've swapped the cap for a known good used one - same fault.
Outside of the suppression (where do you get those from and can I run without?), any ideas why else it might not spark on that one cylinder or what other tests I should be doing? Thanks!
