Z won't start ...
 

Car was in govt storage for 2 years and every month they start the car and drive the vehicle around. I noticed when I got the Z back that they had replaced the ECM a few months ago. I picked up the Z first week of May and it was fine. I went on vacation for 3 weeks and now the Z cranks just fine but it won't turn. I got my batt tested and charged. Came back home connected back the batt and still doing the same thing. Cranks good but doesn't turn over. I'm going to check the starter relay and fuel relay. If I can't resolve the issue by replacing the fuse. What should I do next?

Tow it to a mechanic to get it checked out, the only things i can see are

needs new spark plugs
fuel relay is shot
or you need a new started like you stated.

I removed the starter and fuel relays but from the look of it they look brand new. I called around they don't sell it! I'll check the spark plugs...
