Hello and thanks for using Just Answer.I will try my best to help you with your question.
What year Lincoln do you have?
What Model Lincoln do you have?What engine size does your Lincoln have?
It sounds like you IAC (Idle Air Control) valve is bad. This valve allows your engine to idle when your foot is off the gas pedal. It allows air to enter the engine to keep it running. Try cleaning out the IAC and see if your problem stops. If not, replace the IAC. It is located on top of your engine under the engine cover.
so you dont think it has nothing to do with my fuel pump
