Hey guys. I'm working on an 89 RS with 305 TBI. I'm having some issues getting it started. I've done a bit of troubleshooting, and here's what I've come up with so far.

Fuel pump is working, I'm getting good constant pressure all the way up to the throttle body. If I spray starting fluid, it will fire and run, then die. So it seems there may be an issue with the injectors not firing. I've used a test light, and with the key in the RUN position, the 'A' wires to both injectors light up, and the 'B' wires both are dark. Injector fuse is good as well. I also tried unplugging the TPS to see if that got any results. Basically I'm trying to figure out if it's an electrical/signal problem, or if the injectors are just clogged/bad. Any insight, or further testing methods would be greatly appreciated. TIA.

You've lost second injector power.
Your second injector power should look just like the first injector.
With key on, engine off, power should be at both wires at injectors.
With key on, engine running, the colored wire goes to the ECM and ECM places a low voltage on the wire to open injector.
ECM colored wire comes from the ECM driver.
Black(?) wire comes from battery/fuse/relay.
