Thanks in advance for any suggestions.What should I do first to a 1992 fuel-injected Miata that sat parked for 3 years in order to drive it?
First use a flushing oil, then change the oil and flush the radiator and refill with a mix 50/50 water antifreeze. Fit new wires, spark-plugs and fit a new distributor. Clean out the old fuel and put in fresh gas and a full bottle of SeaFoam or B12 to rid the system of gum residue into the fuel tank. Fit a NEW battery. Remove the spark plugs and spin the engine over a couple of times and then refit the spark-plugs and you should be good to go. However, ask yourself why the vehicle sat for three years unused.

What should I do first to a 1992 fuel-injected Miata that sat parked for 3 years in order to drive it?Put fresh gas in it, a good battery and run the car normally. The rings should not be stuck unless the engine had a bad head gasket when you stopped running it. You can change the oil to be sure about it. I'd use some Mechanic's Engine Flush. I've restarted cars that sat longer than that and they drove fine.
Mmmm Get a new 600 amp battery, hook it up and turn the key. That is all I would do. Same oil, same gas, same coolant. same plugs. It will most likely run just fine. May stink a bit more but no biggy. Soon that is gone.What should I do first to a 1992 fuel-injected Miata that sat parked for 3 years in order to drive it?
Yea you know what to do. Don't forget to flush the brake fluid and chase the mice out too!
