My friend has a 2003 4.6L expedition with 190K miles. Runs good and drives good. Its spins more times than normal before starting although it always starts and runs fine. She now engages the starter about 2 to 3 short spins and it always starts. No OBD II codes set and runs good under acceleration and idle. We haven't checked fuel pressure at the fuel rails. Air Filter is new and good. Replaced fuel pump recently. Problem was present before and after fuel pumps change. Any thoughts on this one?
