WHEN PUT IN GEAR KILLS ENGINE IF NO BRAKE APPLIED IT WILL DRIVE BUT IF STOPPED DIES
check out your alternator
Sounds like it has to do with the micro-chip in the key. Starts for about 3 seconds and dies. In 1999 Ford installed a micro-chip in the ignition key for Anti-theft purposes. If the chip isn't there, or is malfunctioning, the vehicle starts briefly and dies.
Your idle air control valve may be dirty or clogged, the fuel filter may need changing or the rpm is set to low.
Problem with your alternator, possibly the diode pack or brushes. Remove them, (Can be done without removing the alternator) New unit for this is about $30 .
Everything Dies was created in 1999.
Slows, stops, or smolders.
WELL YOU MAY HAVE EITHER A BAD ALTERNATOR/CONECTION OR YOU ARE DISCONECTING THE NEGATIVE SIDE OF THE BATTERY FIRST. TRY DISCONECTING THE POSITIVE SIDE FIRST IT SHOULD THEN STAY ON.
A possible reason the engine dies when the oil light comes on in a 1999 Ford Escort could be because it is in major need of an oil change. There also could be an oil pressure problem because the oil pump may need to be replaced.
The idle sensor needs changed. Just had mines changed, I was having the same problem as you are having
that just happened to me last week.i had a simple vacuum hose leak so that should be the only problem
Check your fuel filter, it may need replaced.
