Any way to disable Fuel injector?

[pt80chip]

Hi Everyone, I have a 2002 Impala 3.4 and need to disable a fuel injector for a short period of time (1-2 hours). Is there an easy way to do that?

 

 

On my brother's Lumina you can unplug each one easily but on the Impala the plugs are not easily accessible.

 

 

Thanks in advance

Not without pulling the upper intake.

"easiest" non-destructive way would be to remove the pin that controls the injector you want to disable from the injector harness.

as he said, pull the inj ground wire/pin from the inj harness connector....all you need for em is a small sewing needle or safety pin needle.

 

google metri-pack or weatherpack pin or terminal removal

I see that there are a bunch of things connected to the intake, will this be a needlessly complicated task or is it just a handful of bolts?

There is an intake manifold above the injector plug, do you know if I can remove it without taking out the manifold? I have tried accessing the pin with a tiny screwdriver but I'm not convinced it's possible.

Sorry guys, I just realized that I replied 3 times to the same thread. Since I am logged in the answers weren't showing up, now I checked a different browser and see my respond 3 times

you wouldn't be disconnecting the pin from the injector plug itself, just the injector harness...

 

here's two images to give you an idea. looks like the injector harness connector is right by the coilpacks.

I see, so in other words follow the injector cable to the harness, find out which pin controls the injector for cylinder 5 and disable it. Any tips on how to disable it?

Also, which pin would it be? Is your image specific to my car?

that diagram is specifically for an 02 impala w/3400. should be able to match the colors to verify pin position before pulling it.

 

cylinder 5 is in position G, black wire with white stripe.

Thanks for all the info. I disconnected the two parts and the plastic is pretty brittle. Already managed to break a few pieces. The connector is a little stubborn, is there a secret to removing the pins?
