Default Compression test: disconnect?

Hello all,

I'm going to do a compression test on my 95 today. I have read a few posts on the site as to how to conduct the tests (dry/wet), but I haven't read what I should disconnect.

As far as ignition, I just unplug the coil right?
How about the fuel? What do I disconnect?

Thanks for any help,

Joe

Theres 2 Fuel Injector fuses in the box inside the passanger door. Prob a fuse for the pump somewhere too.

yep just unhook your coil and unhook fuel pump relay if you dont want the fuel. you can do it with the fuel on it really isnt going to make that much of a diff.

Good deal! Thanks everyone, I'm eager to see what the numbers are (i.e. how much work awaits...)
