Run Test NS-5B Repairing Fault "Ignition Control Circuit"
So spent some time today and still no luck:
Spark: Tested for spark and first wasn't getting spark on #1 (using adjustable spark tool) . Stopped there and checked wire checked coil connector. Using the diagnostic manual checked resistance at the 3 wire connector on coil, both at .8 so that should be good. Had my brother cranking the car and all 3 wires to the coil at the connector jump to 11-12v while cranking. I got a new neon coil and made up an adapter harness. Verified that the adapter was wired correctly and tried it. Still no spark. Unhooked the SBEC 60 way connector and tested continuity/resistance on the 2 coil wires 17 & 19 both test less that 1 ohm (tired 2 different multi meters). Sprayed elec contact cleaner on the 60 way and SBEC. Followed the wires back to the 2 10 way connectors behind the battery and spray cleaned them too. Wiggled wires while testing continuity/resistance and no change. Hooked the original coil back up spark on 1 & 4 but no on 2&3. Check wires again, still good, check voltage at coil connector while cranking and still jumps to 11-12v on all 3 wires. Hook the neon coil back up and pretty sure for a short while I got spark off 1,2&4 for a short time but no on 3. Tried different plug wire but no. While verifying I still had spark on 1,2 & 4 , #2 was no longer showing spark. Put the original coil on and still just 1&4. Only 2 things I can think of that could be wrong is some how the connector for 2&3 isn't making good contact when in the coil (or coils) did spray it and light amount of new dielectric. Or computer is bad, which to me doesn't make sense as I get voltage from that wire while cranking?
Fuel: Using a noid light verified light blinks at each injector
MAP Sensor: Using my OBD1 scanner showed that while cranking the voltage does vary every so slightly while cranking (something like 2.12 to 2.14v)
O2 sensor wiring: Did look it over. Did a reroute years back and the wires still look good. Believe the OBD1 was showing .6v (not sure if that's good or bad?)
