pt80chip Posted February 24, 2013 Report Share Posted February 24, 2013 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 Quote Link to comment Share on other sites More sharing options...
White93z34 Posted February 24, 2013 Report Share Posted February 24, 2013 Not without pulling the upper intake. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted February 24, 2013 Report Share Posted February 24, 2013 "easiest" non-destructive way would be to remove the pin that controls the injector you want to disable from the injector harness. Quote Link to comment Share on other sites More sharing options...
Turbocharged400sbc Posted February 24, 2013 Report Share Posted February 24, 2013 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 Quote Link to comment Share on other sites More sharing options...
pt80chip Posted February 24, 2013 Author Report Share Posted February 24, 2013 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? Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...

RobertISaar Posted February 24, 2013 Report Share Posted February 24, 2013 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. http://i.imgur.com/dUQwIF1.gif http://i.imgur.com/pDfdNio.gif Quote Link to comment Share on other sites More sharing options...

Any tips on how to disable it? Quote Link to comment Share on other sites More sharing options...

RobertISaar Posted February 24, 2013 Report Share Posted February 24, 2013 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? Quote Link to comment Share on other sites More sharing options...
