It's an easy fix...
1-remove the bezel surround the spedo cluster... (2 Bolts at the top)
2-you will see 3 wires possiblly taped directily above the ignition where the key goes in. (yellow, black, and white)
3-cut the yellow wire (your security light will come on and stay on but the problem will no longer bother you)
4- if your battery ever dies you will need to reconnect the wire (some people put a toggle switch in to elimate this)

*Hope this helps tried on 2-3 cars and works perfectily every time for months now... One friend claims it has been a year and still no problem...

Its a anti-theft problem ( you already know that) but to fix, a shop or the dealer will have to check further and determine why its not recognizing your key.

What could be the causes of injectors not opening and spark plugs not firing


A long list of things. From fuses to ignition switch to ecu to security alarm and more.

Here is how to start looking: Turn the key to on. Do the dash gauges and warning lights and check engine light come on? Then power is getting to the switch and being sent out from it. Next, use a test light and check for power TO the coils and TO the injectors with key on. All four injectors use the same color power wire. My wiring diagram is poor quality, but it looks like a green wire or possibly a gray wire-remember same color power wire to all injectors-the other injector wire is a ground wire, and they are all different colors. Pull one injector connector off and check for power on one terminal with key on. And could do the same at the coil pack. With key on, the white wire with red stripe to the coils should have power-actually, the white wire is spliced and two white wires are shown going to coil pack-this is the primary current to the coils- is hot in run or start.

If no power to coil or injectors, here are the fuses to check: in the under hood fuse/relay block: ecu-10 amp fuse, Eng-15 amp fuse, and these maxi fuses: fuel inj-30 amp fuse, Main- 80 amp fuse, Ign-40 amp fuse. And one more- a designated Main fuse-15 amp fuse.
If these fuses are good, should have power going to injectors and the coil pack with key on. If the key is turning on the dash, some of those fuses are known good, but need to check all of those listed.

I will stop here, and wait for your reply. You get this far, you are on the way to diagnosing the problem.

Security alarm will not release to let ingine start is there anything i can do?


If you dont have the remote for the alarm you can try disconnecting the battery and then turn the key to the on position and then reconnect the battery and try to start. sometimes that will get around the alarm

No heat thermostat isopening and closing andfanis working sometimes you get a little barley warm air then it goes back to cold air also ck. eng. light is on


Ck Eng light probably not related.
The heater core is clogged. A bottle of cooling system "quick flush" may be all you need ($6 AutoZone).
There is also a complete flush system, but requires that you splice into the heater hose (I installed it on my Taurus - works great!).

By the way, there is a heater core bypass hose. It is connected to the two heater core hoses near the firewall. You may want to remove the two "Tee" fittings and use a 5/8" hose splicer so that the flush passes through the heater core at full force. Put the Tee's back in place after the flush.

If you remove the tee fittings and don't flush, the heater will work, but the core may eventually start leaking.

Ingine will not turn off after taking keys out . Everything else goes out but ingine keeps running.


Sounds like a faulty ignition barrel! If you take off the trims underneath the steering column you'll be able to gain access to the ignition barrel casing where the key goes. By undoing the casing you'll be able to turn off the engine with a simple flat bladed screwdriver.

Ignition barrels arent too expensive to have replaced, the other problem that might occur is the chance of needing a new set of keys or to have your current keys programmed to the new barrel (Normally a new set of keys is the common procedure with a new barrel)!

Hope this helps
