I need to know how to replace a fuel injector on a 1996 Chevy Lumina with a 3.1L engine. If you could help me with that it would be great.

You will have to remove the upper intake manifold, throttle body. Also anything else that would be in the way (MAP sensor, coil pack).

Then remove the fuel rail by disconnecting the fuel lines (special tool required available at most autoparts stores).

Injectors are held to fuel rail by clips, remove clip then injector. The injector connections are numbered.

Cylinders on firewall side (from passengers side to drivers side are 1-3-5 and on front from passengers side to drivers side are 2-4-6) Firing order is 1-2-3-4-5-6.

Get a manual from the link in this thread, or a Haynes manual. It will make it much easier.
