Update:
Had a chance to play a bit more.
Bus won't start at all now, so that is good news.
Things it is not:Fuel flow appears fine (new pump, tank screen is clean)   fuel flows well from the pressure test screw.Temp2 sensor was replaced.TPS ok, I think.   clicks right away when you move the throttle, pins seem to read correctlyNew coilNew cap/rotorNew air filter since I had one
Things to do:Will check spark tonight when I have a helper.Afm, moves nicely, but unsure how to test.I don't think the injectors are firing.   No smell of gas.I have a spare distributor.   Existing distributor has a very loose wiring socket, and some plastic bits inside it.  Everything seems brittle.
Questions:Is there something to look for on the ecm that would indicate a sign of life?Something to indicate the afm is healthy?I'm pretty sure I have the pump hooked up correctly, but would there still be a lot of fuel at the pressure test port of it was hooked up backwardsIs taking a pair of injectors out the best way to see if the injectors are in play?
Thanks!
