Deliberately Cranking without starting

Hi all,

Does anyone know which is the best fuse to pull to crank the engine without starting in AND not losing any ECU short & long term memory?

My car gets driven quite rarely (every few weeks in the summer), and I want to be able to build oil pressure before starting.

Thanks in advance.

If you look on the underside of the fuse box cover (the one in the engine compartment), they are labeled.  The one you want is 'EFI'. 

On my 1ZZ,  it's the first one in the long row of fuses, blue 15 amp. 

It will cut the injectors.

Perfect, thank you.

I'm still using the 1ZZ loom, so will be the same for me.

I usually pull the top two 15A in the left side row,  I wasn't totally clear what each did but I thought it was fuel & ignition.

I've done this on my car before since it sits for weeks sometimes. I usually pull the fuel pump fuse to crank it without starting—works like a charm for building oil pressure. Just crank it for about 10-15 seconds, then pop the fuse back in and you're good to go. Never had an issue with losing ECU memory doing it this way either.

Which fuse is the fuel pump fuse?
