Well despite the spark tester showing good spark, visual inspection of the plug grounded to frame sparking replacing the plug has corrected the problem. Thanks for the help

Yes fuel delivery doesn't seem to be the issue and it has spark and compression. Maybe a relay or ECU issue?

I have a 2012 420 that will crank but not start. All in one afternoon it started by stalling at an idle and would restart but hard to eventually a complete no start. Having read that fuel filters and pumps were common this is where I went first. My mistake for not taking the time to collect the correct testing equipment before replacing the fuel pump and filter with Honda parts and still won't start. Has compression, spark, fuel to the injector, fuel spraying from injector when tested out of the machine. Am I looking for a relay or something else that's causing this. Battery is fully charged and has had a tender sitting on it since this started. Any help would be great. Thanks
