Put a set of plugs and wires in it before you spend (waste) any more time with diag. If you are getting voltage flow into the wires (you already confirmed this with the timing light check you did) and you spray some ether in and you get no start then it is either fouled out plugs (very likely with a borderline spark quality) and you have already proven you have at least one bad plug wire and that is probably the reason your plugs are fouled out.


P.S. DONT USE BOSCH PLUGS !!!!
