🔧 CRANK / NO START — DIAGNOSED & FIXED! ✅
This 2016 Dodge Charger 5.7L HEMI was cranking but would not start, so instead of guessing and throwing parts at it, we worked through the system step by step.
We started by checking the battery/charging system, fuses, and relays. From there, we moved to ignition, removed the spark plugs, and physically verified that the engine had spark. With spark confirmed, our diagnosis led us over to the fuel system.
⛽ The fuel pump was not priming, even though the relay and command to the pump were working. After probing the fuel pump wiring, we found heat/burn damage at terminals 4 & 5 of the fuel pump connector.
Based on our findings, we:
🔧 Replaced the fuel pump
🔧 Replaced the fuel filter/secondary unit
🔧 Removed the damaged connector and installed a new fuel pump pigtail
🔧 Wired the updated connector according to the proper configuration
🔧 Retested the system
Turned the key and she fired right up! 💪🏽🔥
This is exactly why proper diagnostics matter. A crank/no-start can come from several different systems — our job is to test, verify, find the failure, and repair what the vehicle actually needs.
