Hello, installed a remote starter in a 2005 buick allure. prostart ct-3471 tw and fortin Int-sl+. Used wire color and autostart wiring color guides. Used fortin int-sl+ schematic 1. Had unit start once with remote starter. Tried again, have not been able to start since with remote starter, still starts with key. when using remote, dash lights quickly light up, and then go out, does not crank. tried reprogramming int-sl+, loaded newest software v3.06. I am out of ideas. This vehicle was previously equipped with factory remote starter, noticed yellow ignition wire in ignition harness is +12v pulse, will not stay pos for duration of cranking. Please, any advice would be appreciated. Thanks, MIke Unger.
