Car Alarms: 99 Expedition Wont start, side kick panel, negative polarity

Question
I have a 99 Expedition that wont start supposedly due to the alarm killing the ignition? The engine turns over but does not fully start. I've tried to disable the alarm but still won't start. I have an aftermarket and stock alarm. Does the toggle override the factory alarm. Please Help

Answer
I don't think this is a after market issue.
If it were, the engine would not even crank.
It can either be the Ford PATS system
that needs to be reset, or the factory alarm
holding you back.

Ok, if the OEM alarm malfunctioning now,
(car horn blarring and head lights flashing)
odds are, it will again.

Get out some basic install tools or get
a friend or a good technician
in there to do this.

Normally, you would insert the key in
the drivers door, turn left, then right
to disarm and reset it. If yours is malfunctioning,
you can disable it for good by doing the following:

The FACTORY ALARM
DISARM WIRE IS THE DARK GREEN/VIOLET
|- negative polarity|
at the harness coming out of the door
in the driver's side kick panel.

Once Located, splice into this wire with
a simular guage wire, and put it to
a solid chassis ground. This terminates
the OEM alarm functions entirely.

However, at this point, this car would be exceedingly
easy to steel, so I suggest you get an aftermarket
alarm system to protect it from here on in.

Have a good day.
