221: Start/Stall Cadillac CTS Diagnosis
About this episode
A detailed diagnostic case study of a 2013 Cadillac CTS experiencing a start-then-stall issue. The host investigates whether the problem is related to the anti-theft system, fuel delivery, or sensor data, ultimately discovering a ground fault at a key relay ground point. This faulty ground caused voltage issues that intermittently cut injector pulses, leading to stalling. The episode highlights the importance of not ignoring recurring codes, even if they seem unrelated, and demonstrates thorough diagnostic steps including scanning, data PID analysis, and electrical testing to pinpoint the root cause.
Today on the show I share a case study on a 2013 Cadillac CTS. This vehicle starts and stalls, but the shop has done their best to eliminate the anti theft system as the problem. I'll confirm that, but then figure out what else is causing this issue.
