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. Key on negine off fuel pressure specs are 35 to 45 psi and it should not leak down with the engine off (or key on engine off). If it does, it is likely a bad check ball in the fuel pump going bad and the fuel pump will need to be replaced. That will get you back up and running good again!
YES, the fuel pump is located in the fuel tank. There is a check ball inside the fuel pump that only allows fuel one way (to the engine). But yours has failed so it is allowing fuel back into the fuel tank when the fuel pump stops running.
The engine can start and run on low fuel pressure. But it wont run very good.
I am glad I can help!

In theory, YES. It could be bad. However, based on my experience, if the ignition module were bad, the engine simply would not start. By yes, you can certainly check it out as it would not hurt just to be sure.
