Hello....The ECM on your camaro has one (1) injector driver in it. This drive splits to 2 traces inside of the ECM and exits on 2 separate pins.
Each bank of injectors has its own fuse. So a fuse may have popped. Check the wiring harness and check for bad grounds.
To check the injectors measure the resistance across the injector pins. It needs to be above 14 ohms. Best if checked while they are hot.
Good luck, i hope this helps.

On my 89 Camaro TBI V8 305 I am only getting fuel from one of the injectors. I am only getting power to the driver side of the fuel injectors.

Sounds like the injector wiring harness is bad. I would check for voltage at the plug and chase the wires to find the short(open wire) in the harness.

I have an 89 camaro rs and the feul gauge is stuck on full. is it the sending unit or something else

Most likely it would be the tank sender unit,but it could also be the dash gauge and or possible wiring. When u turn off the key , does the gauge go to a different position ? If so, then probably the tank sender, if not then the dash gage.

Transmission for an 89' Camaro Rs ?

Definitely you can save by buying used. Check for local auto dismantlers in your area. Be sure to ask them what kind of mileage the car had on it when they pulled the tranny. Also replace filter and pan gasket while it's out.
