Troubleshooting the Fuel Pump Control Module
Before you spend $500 on a new fuel pump, make sure the controller isn’t the real problem. This guide covers symptoms and the “Key-On” test for modern trucks.
Top 3 FPCM Symptoms
- ✅ Extended Crank: Engine turns over for 5-10 seconds before firing.
- ✅ Stalling: Engine dies at stoplights or while cruising.
- ✅ No Pump Prime: You don’t hear the 2-second “hum” when you turn the key on.
