Hi everyone!

It's been a while since I've posted anything here. Eventually, I sold my 1994 Blazer to a friend and my wife sold her 2000 Blazer to my mom who took it away to Nevada. However, my 1993 Jimmy is still around. I set it aside and didn't do anything with it after about 2014 because the oil lines started leaking badly and the starter went out. Now it has been sitting since 2014 without running. This weekend I want to pull it out of the weeds and get it back on the road. I know I'm going to need a new battery for it and a new starter. I'm also going to need to pull the oil lines and get them rebuilt with high-pressure hydraulic hose. Aside from that what else do I need to do to get it back in good running condition? Do I need to do anything about the old gas in the tank? Should I do anything to the old oil in the engine before I try and start it again?

 

Definitively dump the old fuel and check for rust in the tank. Eventually removing the pump assy. Fuel filter should be replaced. Check the fuel lines.

For the engine I would remove all the spark plugs and have a close look, possibly with an endoscope.
Then hand turn it with a socket, best from beneath on the crank. Some have successfully turned the engine at the alternator bolt, but I'm not a friend of applying that much torque to this part.

I would in any case change the oil, and prime the oil circuitry through the distributor. That means you need to be comfortable in removing the distributor. The other option is to build pressure by removing the fuel pump fuse and turning the engine over with the starter. In any case I would prime the engine with oil before the first start attempt.

 

Thanks for the good, thorough response!

I had thought about the old fuel and planned to at least drop the tank and give it a look. I know that after six years the gas has probably separated and would have absorbed at least a little bit of water. The tank will need some attention to ensure it's still in good condition.

I'm planning on removing the oil cooler lines to have them rebuilt. I'm thinking I should drain the current oil (since I have to do that to remove the cooler lines) and then replace it with fresh oil before cranking some oil through the engine. I don't have an endoscope for looking in the cylinders, though, so that's not likely to happen.

I'll post back here as I get through the process of putting the Jimmy back on the road.

 

Once you pull the spark plugs you will already have an idea what it looks inside the cylinders.
Good luck, that it held tight over the years and will run fine.
