Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and welcome!My name isCustomerand I can assist you with your question.
Can I start by getting your VIN?
Thank you for that information.
If there is no communication with the PCM, then this is why the starter is not engaging. The PCM controls the starter relay.
You could have a blown fuse, faulty PCM or a wiring issue. You will need to check all powers and all grounds going into the PCM with the key on to ensure proper inputs. If all checks out good but the PCM is not commuicating, the PCM is at fault and will need to be replaced.
Thank you for that information. So if the wiring up to the PCM is good and the PCM has the correct inputs with the key on, the PCM is at fault and will need to be replaced.
I am glad I can help!
