Hey Folks! New member here! I just purchased a 2007 Yukon (I know not a Chevy not a Tahoe). It didn’t have any key fobs so I purchased some. Programming worked great, everything works except the remote start. I hit the lock button 2x and then the start button and I can hear the fuel pump run but it doesn’t start or even engage the starter. It has 3/4 tank or fuel, all doors and hood are shut, including the back glass. The only light that is on in the dash is tire pressure sensors. I’m guessing the battery’s are dead on the TPMS. Would that keep the vehicle from starting? No keys in the ignition and I have both key fobs in my hand. Remote start IS enabled on the DIC. This has me baffled. Please help!
