how to diagnose a vehicle has unknown problem?

I inherited 2005 Mercury Mariner with unknown problem. besides that its been sitting about 3 yrs.

where do I start after I check to see if engine is not frozen? it was abandoned in his yard after a problem I don't know about. I assume it wouldn't run.

I'm getting a battery, gonna squirt marvel oil in the plugs. my bet is electrical or brain issue but I have nothing to go on. its high mileage I'm sure so ill guess over 250,000.

any help appreciated.
