No SECURITY light, no start - ZR-1 Net Registry Forums

Recently I replaced a broken wiper switch in my 1991 ZR1. At the same time I had the intake plenum off to repair a broken secondary vacuum fitting and replace the plug wires. Time to start the car and no SECURITY light and the starter won’t turn over. Spent considerable time going over old posts on this subject and performed all the troubleshooting. The VATS key resistance at the connector under the dash is correct. No CCM or ECM codes result from running diagnostics. When running system light checks using on board diagnostics, the SECURITY light works. Starter doesn’t work when jumping the large purple wire to the solenoid to battery positive with the key on, and clutch depressed. Clutch switch works. The interior lights do not come on when either door is open. Removed Haibeck chip and tried original chip and that didn’t help, put the Haibeck chip back in. Battery is charged. Except for no SECURITY light, all looks normal when key is in the run position. There’s no draw down on the circuit when go to start so appears to be an open somewhere or the VATS is not talking to the start circuit. I want to retain the VATS because I live near San Diego and work in San Diego and the border to the south is an open road for stolen vehicles. Any insight or help would be greatly appreciated.
