Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here. In order for the engine to start and stay running you need good spark to the spark plugs, injector pulse at the injectors and proper fuel pressure. In order to determine why your engine is cutting off you need to start with checking to see which one of these to you are loosing when the engine stalls starting with installing a fuel pressure gauge and monitoring the fuel pressure on your new pump. If you can get this done and post back with your results we can work from there to determine the cause.
