Random No-Crank Issue

A vehicle that randomly refuses to crank, especially with no pattern, points to more than just a dead battery. Here, the starting system is tested from the ignition switch through every control module and relay that stands in the way of starter engagement. Voltage drop, current path verification, and logic-level signal tracing help pinpoint exactly where the signal is lost. 


Whether it's a failed clutch interlock, a corroded relay feed, or a module that missed a wake-up command, the cause is isolated and confirmed under real-world conditions.


When it's not consistent, that's exactly when it needs professional-level testing.
