i have a 91 four door integra. i borrowed a compression tester from a friend and now i need to know which fuse to remove so no fuel comes out the injectors, photo would help. also i can search for this one but does any off hand know the psi i should be pulling on each cylinder?

You pull the ecu fuse (usually 15 amp). In most obd1 civics and integras it is the top left fuse (don't know about obd0).

I get around 190-200 through all cylinders (b18b1).....remember to hold the throttle down/open.

Or you could just pull all the plugs/wires since you will have to do that anyhow?

But if you just pull the plugs/wires, you would still be getting fuel sprayed into the cylinder.
