Well, finally got the rear drivers side brakes done. Replaced everything, even backing plate. Went to reposition in garage and now won’t start. Will go thru the normal progression. But, haven’t checked, does this year have a diagnostic port? Has pretty much all dash lights. Did have some hesitation issues and random engine light flickering before I put it in for brakes. Any thoughts? Thanks and be safe.

Does it not crank? Or crank but not start? If it cranks then the battery/alternator are ok. You need 3 things to run; fuel compression and spark.

Cranks. Figured fuel, spark or compression. Old fuel filter, starting there first.

Sounds like an ignition module to me. Fuel is easy to test by putting some gas down the carb, spark pull a plug wire and ground the end of the plug to the engine while cranking over.
