Only one working fuel injector ...what to do?
My 92 has been running pretty rough the last week. I decided to do a tune up. But when I removed the air clean I noticed that the drivers side injector only sprayed on start up.
What should be my next move? Should I change the injector? If so what brand? Should I change both the way you do headlights because the passenger is likely to go? Should I get one from the junkyard to temporary solve the problem? Any tricky issues with changing the injector? Can I fix the injector that is in there or just get a new one?
FYI: 305 TBI, probably has factory injectors on them.

Re: Only one working fuel injector ...what to do?
I don't know if it'll help, but I have a few TPI injectors that you can try and see if it is an injector or something else. I have mostly 22 pounders but I may have a set of 19's in this heap I call a garage! How far are you from Elk Grove Village?

if you have a test light just see if it is being commanded on and if so get injectors, if not you have other issues

Guess my help wasn't needed then, oh well, glad you got it fixed.

Re: Only one working fuel injector ...what to do?
When I was getting my LT1 running, I couldn't get it to fire. Finally gave up after testing all the injector plugs with a Noid light. They were all good, so I did the reverse, wired ground and 12v to each injector listening for a click.
Only 1 clicked. 7 of the 8 injectors were seized. Good thing I had a set of Ford SVO 24# injectors laying around from my old TPI engine.
Thanks Jeremy, still running, years later.
