INSTALLED NEW SPARK PLUGS RECENTLY AND SEEMED BETTER. BUT DIDN'T FIRE UP THE OTHER DAY.
BECOMING UNRELIABLE.
Next time it refuses to start do below to determine if its fuel or ignition related problem
Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil, distributor pick-up coil, ignition control module, cam and crank sensors-
