I have a 1300 cross flow engine in a kit Jeep, always been a bit slow starting but now it won't at all have fitted new coil and spark plugs. Made sure rotar arm and dist cap is good. Still it won't start also checked fuel filter which is fine hasn't started for about 6 weeks now ... Not tried bump starting it yet thought I would ask on here before I tried that, all leads were new last year as well
