Background. Car runs great no issues at all. BUT, steering gearbox was leaking badly, so I replaced it with new unit. I had to remove plug wires, headers, steering column to get it out. I put everything back, went to start it and pop pop pop. #5 and 7 plug wires were switched. I changed them back. Went to start again and it will stay running as long as I keep the key in start position and my foot on the gas. Let the key off and it dies. Any ideas?

See if you disrupted the wiring at ballast resistor, ecu and/or main bulkhead connector.

Thanks, I thought it might be the bulkhead connector. May have happened when I removed the column? Could having the 5 and 7 plug switched cause it?

4 pin ballast? (1) pulloff both connectors and ohm it. a high mileage one I had measured 1.6 and 6 ohms. (2) see if the end connector w the blue loop gets fire w key in run (ign1) and that the brown wire on the other end gets fire w a helper holding the key to "start" (ign2).
