Dear people, hope one of you techies can help me.

It is a Ford F-150 Bj 2001 5.4L triton Lariat version crew 4x4.

The truck will not start properly when the engine is cold (seems to be drowning) And when the engine is warm, no more power, but it does start well!?
When reading no error codes, I made a list of what happened to it.

New head gaskets (heads flattened and overhauled).
New distribution chains.
New spark plugs and ignition coils plus new plugs.
New fuel pump plus fuel filter.
New camshaft sensor.
New crankshaft sensor.
New fuel pressure regulator.
New temperature sensor in the air filter tube.
New EGR pressure regulator.
New fuel pump relay.
All vacuum lines checked and not leaking.

Maybe I forgot something, can someone help me with this problem?
Or a garage that can read the truck completely, have the license FORscan itself, but I have the idea that it does not read everything.
Hope to find a solution soon (if possible).

Yours sincerely.

Wim (from Holland)
