Has COMBUSTION when ign is held in start pos but dies when sw is released, correct?
22RE? Look for fuel pump check connector, short FP to B pin. Also search how Circuit Opening Relay works on my thread.

OK, I unpluged the TPS and the engine started and ran. Cleaned the plug and connector with contact cleaner, used dielectric grease on both pluged up TPS and all is well. Then did the same on igniter connectors and dist. connector. It is running. Thanks again guys.

So.. Shorted five volt vref in the tps harness probably. Which means when it tried to change from the start to run condition and didn't get ignitor feedback IGf (iirc) it wasn't sending IGt.
