Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello, My names Kurt, and I will be helping you today. Sorry you are having issues with the truck after all that work.
There are two common things that cause this code on the 5.4L The first thing is to make sure it has the correct amount of engine oil it, since everything is ran off of oil pressure, this is the very first thing to check.
If that checks out, we need to go ahead and check timing on this truck. It really sounds like the timing may have jumped on you while going back together with it. I know thats not the answer you want to hear, but chances are, thats the issue. It happens A lot more than you think to people.I attached a PDF of how to inspect, and correctly time the engine, in case that is the issue.Please feel free to ask me any other questions, and ill do my best to help so we can get this truck up and running correctly!Also, please do not forget to rate my service tonight!Thank you
