TBI injector problems.

[team39763]

I have a 94 S10 with a TBI 4.3L. A while back, we had problems with it misfiring and stalling. So we checked a few things and it looks like the injectors aren't firing. I checked to make sure they were getting power/signal, and they were. They just didn't fire, so I assumed they were clogged. So I pulled the injectors out and soaked them in some B-12 Chemtool, then blew them dry with high pressure air. I broke the gasket between the top/bottom plate, so I used rtv and bolted everything back together. When I went to turn it on, both injectors just poured gas out(not spray). One of them foamed up pretty good, but they both were just spilling gas badly even with the electrical connector removed. Did I ruin the injectors or do I just need to replace that gasket? Any help would be greatly appreciated.
