Summary of "Engine Cranks But Will Not Start"

The video titled "Engine Cranks But Will Not Start" features a diagnostic session on a 2012 Jeep Grand Cherokee Overland with a HEMI engine. The main issue is an intermittent no-start condition, where the engine cranks but does not start. The customer initially believed the remote start feature was malfunctioning, but the problem was determined to be unrelated.

Key Technological Concepts and Product Features:

Diagnostic Tools: The hosts utilize a Chrysler factory scan tool to identify issues with the vehicle's modules, particularly the Wireless Control Module (WCM).
Crank Signal Analysis: The video discusses checking the RPM reading during cranking to confirm the crank signal is present, which is essential for diagnosing starting issues.
Fuel System Testing: The hosts perform a series of tests to assess fuel delivery, including:
- Checking the fuel pump relay control using the scan tool.
- Activating the fuel pump manually to see if the engine starts.
- Utilizing brake cleaner as a quick test to determine if the engine will run on an alternate fuel source, indicating a fuel delivery problem.
Electrical and Relay Diagnostics: The discussion includes checking the control side of the fuel pump relay and the potential issues with the Totally Integrated Power Module (TIPM), which houses the fuel pump relay. The hosts suspect that the TIPM may be faulty due to its known issues in Chrysler vehicles.
