Hi I'm Wayne
I will help you with this
Thank you for asking for me
F401 fuse is for the
fuel pump and fuel solenoid
feel if the fuel pump is getting hot
next is remove wire from fuel solenoid, switch to on,
and tap that wire against the solenoid stud,
should be a very little spark
if big spark, replace it
