Im working on a buddys 96 impala ss. With no start fault. Dash does not light up warning light and only displays km turn indicaters are fuctional. Starter turns over with remote. Not able to recognize ecm thru obd2 yes cig lighter fuse good all other fuses are good. I tested key it has proper resistance. Pass key fuses are reciving power when key switched to start But no start. Haynes manuials does not have test points to test pins for anti theft module. Relay tested good. Is this module able to be tested?
