2001 Explorer with 124K, starts right up but runs rough 3-5 seconds and then cuts off. Restart and it does the same thing. Restart 2-4 times before it finally runs good. Does not happen every time, about 2-3 times a week. Spark plugs have less than 25K on them. Any ideas?
You may have a weak fuel pump.
When was the fuel filter last replaced?
Any codes show up? There doesn’t always have to be a CEL on to have codes register.
Let me just add: a fault in the ignition system may cause this interruption.
