Cranks fine but runs rough and dies.

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.

Difficult starting in warm weather

Check the vacuum hose attached to the fuel pressure regulator under the hood next to your intake pull it off and see if any fuel is present, if there is replace regulator.you may have to tap hose with your finger to get any fuel out or start vehicle run until hot then shut off and recheck if no fuel present in vacuum line let me know and we can try something else.

Won't start, engine wont rev above 2000rpm

Have the alternator tested. You are providing a low charge to the battery when you jump it and when taking it above 2K RPM requires more amperage resulting in the engine dying and the rough idle
