930 Sitting for over 4 years. Is it safe to start?

I may have a chance to buy a 930 that has been sitting for over 4 years.

Is it safe to try to start it? What should I do to it before trying to start it?

Hey Kirk, hope all is well!
In 4 years you can assume the gas is bad so drain that. CIS may not be clogged but that's a crapshoot. I'd change the oil, pull the plugs and turn the engine over manually, install new plugs then check for spark. Drain the fuel add new then pull the hose at the accumulator and run a few gallons out. Change the fuel filter and then pull the line after the fuel head and WUR and run another gallon or so out while observing flow. Stick some gages on it and see what system and cold pressure is. Pull the plug wire and turn the engine over to get oil pressure.
That's about it. The initial start will tell you what to do next. Others that have done this many times should chime in with things they have learned to look for.

Dave - Oops, you are correct. Sorry, I'm out of practice.

RarlyL8 - Thanks. I'm hoping to get back into 930's after a long hiatus. Found one that has been sitting for a while that I might try to buy soon.

I think the most important thing is remove the sparkplugs, squirt some motor oil into combustion chambers, remove the fuel pump relays or fuse and crank it over on the starter motor while the plugs are out until it gets oil pressure and crank it another 10-15 seconds with oil pressure.

The other things mentioned are good too but you want some oil spread around on the cylinder walls and rings before starting it first. Sometimes they'll even start on 4-5 year old gas but it's alot better to drain as much of the the old varnish smelling gas thats lost it's octane out and put fresh gas in. Change the fuel filter too.

So, following the above and after it cranks, what would you do with it? Take it for a ride, right? Check for means to stop it, such as: tires, brakes, stearing, TBs & shocks, lights...
Enjoy it!

To add to the above,

I would pull the coil wire and the fuel pump relays and crank it with the fresh oil to get some oil pressure and a little oil circulated before starting.
