Default I think I have a bad injector

My 92 was running great when I parked it for a while. Now it has started blowing the right inj bank fuse.

I'm guessing an injector shorted out but how do I find the culprit?

Not interested in replacing all 8, is there a source to find a good OEM injector to stick in there?

I would start by testing resistance on each of them. If you don't have an ohm meter you can always unplug them one at a time and see which ones pop the fuse.

One 25 year old injector died and you're looking for 1 replacement. You can do the job once by changing all 8, or 7 more times til they are all new. You really want 8 new (or remans) and get it over with

Sooner or later, if they are Multecs especially.

Go with a FIC rebuilt set of Bosch III fuel injectors. I swapped to those injectors when one of my original Multecs read low resistance.

There is a vendor on this web site who will take care of you.

I have occasional access to a flow bench and unbeknownst to them randomly tested before and after. Their results are accurate so they are not doing the BS routine.

You can get one from rock auto but by the time you spend $50 for one plus an oring kit, your almost half way to a full set of Bosch.

I went with these
