You need to check your FICM (Fuel Injection Control Module) voltage. Needs to be at least 46v-48v.

Very. If the voltage is low, don't buy a stock FICM from Ford. You will have to pay for the module and then pay to have it programmed. Check these guys out and go with the 58v upgrade. Swamp's Webstore I just put one in my buddies truck for the same problem and now I think mine is on it's way out.
