How do I disable fuel injectors for compression test?

[Torqstr]

Just wondering, I want to run a compression test on my motor to see if it really is about to die just like I think it is or not, but I don't know how I'm supposed to disable the fuel injectors.

To disable them, remove that plastic rail that goes over them. You will need a flat-blade screwdriver.

Its a very complicated process, First you will need to look on the passenger side of your engine bay and there you will see a fuse box and it will have a fuse labeled "ECU", pull that fuse out and your ready for compression test. lol.

Yea just pull the ECU fuse and no fuel will go into there.

That ECU fuse will not disable the injectors...

You need to pull the ECU fuse in the underdash fuse box, and then you will be good to go.

Don't ask me why Honda did that, because I don't know.

Every CB7 I have tried to start with the underhood fuse removed, started and ran just fine, which means the injectors are working.

With the underdash one, it will not, and the Check Engine light will stay on.

you could disconnect that silver resistor box on the driver strut tower..
