jeffr Posted June 6 Share Posted June 6 I am working on a 1998 5.4L econoline. Just replaced intake gaskets and now the it will only start if you hold pedal to the floor and it will not idle. I have changed fuel pump, regulator, IAC, HTS, and still puzzled. Once started it seems to run ok as long as you keep the pedal pressed. Any Ideas?
