Q? what fuses to pull that will allow the engine to turn over WITHOUT starting it?

After doing a bunch work to replace my existing Setrab home-brewed engine oil cooler, and in the process drained all the oil from the lines and cooler...

Now I want to turn the engine over a few times to get some oil into the lines without starting the Engine and having it run dry.

Note: I have filled the new oil Cooler with oil, but don't have a good way to fill the hoses and remove all the air...except for having the engine oil pump push so oil thru the system.

Q?: What fuses can I pull that will allow only the starter to turn the motor over, bu NOT provide Spark or Fuel to the engine???

BTW: Looking at FSM now for info...

You could probably pull the spark plug wires.

I don't think the Ignition System would like that

Injector, ignition (spark) and fuel pump fuses are the best bet. Don't need the fuel pump one as long as there is one for the injectors, but i'm not 100% sure on how the Z is setup. Can also pull the clips off all the injectors and coil packs, but on these cars they aren't easy to reach.

If you pull the fuel pump fuse the car may start for a few seconds and that may freak you out, I know I did

When this fuse went out on me, the car will turn over but it wont start.

It has something to do with the injectors.

This worked...pulled the Ignition and Fuel pump relays, engine turned over but didn't start....turned the engine over till I got some pressure (careful to not overheat the starter) ...the reinstalled the relays, then started car, then changed the oil...service complete!!!
