Why Does My F-150 Crank but Not Start?
League City · October 2026 · From our shop records
The wiring between the crankshaft position sensor connector and the PCM had excessive resistance, so we repaired it with soldered connections. When their vehicle would not start, a League City driver brought it into our Kemah shop at 236,000 miles. On a visual inspection, our tech found a cracked heater hose. After the wiring repair, the engine still cranked and would not start, and scan tool data showed no engine RPM signal while cranking.
We replaced the crankshaft position sensor and updated the PCM software to the latest available calibration. The team replaced the heater hose inlet.
