Questionhello
I have bought a use ford Taurus recently and it has run fine up until now. The problem I have is when I use the remote to open the door it will unlock it but when I try to start the car the theft light will stop blinking and just stay on and the engine will not start. I made sure that the wires were connected to the battery, then the car started. The next day, today, it happened again. Is my problem dealing with the theft system or the battery? Do you have any ideas to fix it?
thanks for your time John
AnswerTroublesome system, and not an uncommon issue
by a long shot.
Unfortunately, this vehicle's PATS key based engine disabling
system, and it is about to stop recognizing the chip in your key
for good (OR ALREADY HAS!).
My bet is that the switch sensor is going bad,
but I can not inspect that from here.
Now, my expertise is in disabling
the PATS for remote start applications,
but if it's me, on this car, I would suggest
the dei PKFM bypass kit (89.95 AT FORDPATS.COM)
to get around the issue for good.
You will need the original ignition
keys to program it.
This Bypass Module is designed to momentarilly
allow the engine to remote start by sending a proper
coded pulse to open the fuel rail passlock injector
cut off circuit.
The output from an alarm/remote starter
would then shut down the pulse, once it has detected
the engine has engaged, and preserve the integrity
of the PATS system.
That is it's designed purpose.
However, in your case, this input wire on
the DEI PKFM bypass kit, instead of going to a
momentary ground pulse from an
alarm/remote starter, would go to a
constant chassis ground, through
the bypass module, grounding out the PATS.
The PATS would always be bypassed as long
as that wire is chassis grounded.
The trick is that the car's engine has to start
or, you can not program it. &
also remeber, this is IMPORTANT...
You MUST have the original programmed
keys to program the bypass module!
Then any store bought key will work.
One key will do it, but if you try the others
after bypass has been achieved, they will
NOT work, and may even conflict with the PATS.
I can not speak about a damaged PATS system,
like if a thief has destroyed it, because I do not
get into this part of FORD'S security application.
But as a happy coincidence to installing
after market remote starters, this does work on bypassing
trnasponder in most all FORD vehicles we've run into,
including your year FORD vehicle as well.
I can't guaranty it would work here,
however, for the cost might be the best shot you have
before the "total" diagnosis can be verified.
But this does work 95% of the vehicles it's installed into.
In stock.
