Starting for first time in a LONG time

OK so over the last couple years I have completely torn the car down to bare shell including pulling the wiring harness and have been building it back up. This morning I finished hooking everything up needed to attempt a start. Now I still have some stuff to do prior to starting but am getting my checklist together of things I want to do before I actually try to crank it.

Motor has not run since Sept 2018
Looking for suggestions on things to check prior to official cranking attempt.

On my list is to turn the motor to distribute oil.
Run the fuel pump to check for leaks.
Test the electrical system pretty thouroughly.

What else do I need to think about? What would you do on a car that has been completely apart?

When turning the engine over to pressurize oil (without ignition) bring it to full pressure by keeping an eye on the oil pressure light until it goes out. That's how I start mine every Spring.

Mine slumbered a few years longer than yours, but I also pulled all the plugs and shot some fogging oil (or Marvel Mystery Oil is also recommended) into each of the cylinders then turned over without compression to build oil (and fuel) pressure. Kind of a hassle but cheap insurance.

Has the fuel tank, injection system, and lines been emptied? You may want to consider that as well and fill/prime with fresh fuel.

Mine was down for about 5 years, but fired up first crank with the proper prep!

Thanks.
Yes all new fuel lines and tank was completely emptied and dry for quite a while now.

For prestart lubrication in those dry cylinders, you might consider removing the plugs and spraying in fogging oil, then let sit for a while. I did that to my 20 year stored 911. What I like about it is that you can coat more of the cylinder walls than just dumping some Marvel Mystery oil down the plug hole.

Remove valve covers and squirt motor oil on the cam/rocker area. Dry spinning without lube can scuff the cams. Or if you are really lazy, buy 6-7 quarts of the cheapest motor oil and fill the crankcase completely through the breather hose, let sit for a few minutes, drain, remove spark plugs, fill oil tank with desired oil and spin without ignition until oil pressure shows, reinstall plugs and fire it up.
I had an aircraft owner call me to revive a Piper Cub he had parked due to his wife’s extended illness. When she got sick, he just took all the oil he had and just filled up the crankcase to the top and let it sit for 10 years untouched. I drained the oil, let it sit for a day draining, pulled the plugs, hand propped it 20-30 blades, reinstalled the plugs and fired it up, it smoked like a locomotive until the oil burned out of the muffler. Did a compression leak down check, and it was at the upper end of acceptable. The airframe took a little more work.

When we have a motor sitting on the shelf for many years, we fog the cyls with Mystery oil as above, and we "Pre-Oil" the Motor by using a Pressure Pot used for Paint like this......



with 7-8 quarts of Oil set at 30 psi. This is fed through the motor through the Oil Pressure gauge port on the motor.

Yes, its a bit messy, but it ensures all oil passages are fully lubricated before startup.

I can make up fittings for this if you email me.
