1999 f150 4.6 ext cab. vehicle cranks up fine runs rough and dies, I need to hold the thottle open to at least 1100 rpm or the engine dies. The batt and check engine lights are on, when starting cold the choke doesn't seem to be trying to hold any high idle.
Idles rough and quits when gas pedal is pressed less?

Its
a hot start issue.
Can
be related to low fuel pressure or problem with crank sensor.
Also
it can be weak battery or starter.

possibilities are to be inspected to confirm what exactly it is.------
