security system disable?

The keys that you are using, are they actual Ford keys with the Ford Logo on them?

This seems like it is the key issue. Basically it is not in theft mode which is why the theft light is operating normally. It doesn't enter theft mode when an incorrect key or (improperly programmed key) is inserted. It just doesn't allow the start and sets the B code that you are getting.

I have seen this exact issue a number of times when using a Walmart key or some other OEM. The Central Security Module does not like anything but OEM Ford keys. I would suggest getting one from Ford or atleast one that is a known OEM key and seeing what happens. Because the no spark and no fuel is the PCM not allowing the pulse or spark due to the key not being good. This doesn't mean you programmed it wrong, but if it is an aftermarket key then it is just a product that the module doesn't recognize.

Computer problem
2001 Ford F150 V8 Two Wheel Drive Automatic

My truck stopped and the anit theft light kept blinking.
if you let it set for about 10 nin. it would start.
They replaced the PCM module and ran all kind of test on the engine theft system with no codes. We replaced the module that lets the computer read the keys and it still will quit. When it does the theft liight keeps blinking and will not start. We put a brand new computer module in the truck and still have this problem of quitting or not starting until the computer resets. What could be the problem we are stumped.
When we ran test it gives no errors.
thanks in advanced.

WHen you let the key in the run position for 10+ minutes, it should over ride the system. That is why it will start for you. Have you had it checked at a dealer? They are the only ones that have the proper test equipment to check this part of the system.

hi i have f 150 2001 icame home for lunch when i was ready to back to work the would not start the theft light came on then went away then when i try crank the theft light start blinking

Hi:
I hate to say it but the problem lies in the anti theft system. This guide can help us

Please run down this guide and report back.

The theft light is flashing, got a new PATS key but still does not work. Is there a way to reset it? Also, the door locks are not power.

Here is a guide that will help with that:

https://www.2carpros.com/articles/how-to-reset-a-security-system

If this does not solve the issue then we are going to have to scan for codes just to find out what it is telling us.

https://www.2carpros.com/articles/checking-a-service-engine-soon-or-check-engine-light-on-or-flashing

We will know what better direction to go because the flashing light is indicating that there is an active theft issue. So the vehicle thinks it is being stolen and we need to find out what the computer is telling us as to why.

Thanks

I have a 2001 Ford F-150. When I turn my key from the 3 to 4 position my anti-theft light does not turn off. It starts blinking rapidly. A locksmith told me that those keys do not often lose there programming. I went to a salvage yard and bought a 2002(f150) anti theft transceiver and put it on. It still does not disable the blinking light. Could this be do to the part being a 2002 part for a 2001? I used the same wires and plug to the part that were for my original anti theft transceiver. I have the cable (wire+) for the new one as well.

You can't just plug used parts into that system. Everything has to be programmed with a factory scan tool.

My dealership tells my my vehicle is to old for them to have the equipment to fix it. Would a regular mechanic shop have the tools necessary to do this.

Started my truck last night and the theft light came on for a matter of seconds, then went out for a matter of seconds, then came back on and stayed on. Truck runs like normal. Bought the truck with 28000 miles on it in 2002. The theft light blinked like normal until a few years ago, when it stopped blinking at all. I figured it had just given out, cause of the age of truck. Don't know if there is any relation, but the mileage indicator comes on and off, whenever it feels like it. Any idea how I can remedy this situation? Also, will this cause my engine to shut off?

The PATS system in your ford will not kill the engine after it has started, the system is active only until the vehicle starts. You will need to retrieve the codes from the HEC module and more than likely will get a code for indicator failure. The odometer problem is caused by a faulty solder joint in the cluster and can be repaired or sent out to a repair facility for usually 100 bucks or So, avery common problem.

I think we're on to something now, cause I started it this morning and the light went out. When I cut it off, it came back on. Did this several times. Same thing every time. It's a $100.00 to have it scanned at a shop. Will one of the inexpensive scanners from the auto parts store, tell me what I need to know?

The keys were lost to my truck, security was active, so replaced the column. Do I need to put back on or replace the ring in the ignition to make it start? It turns over but will not start.

Hello, I am Danny.

I have attached a tutorial showing an Anti-Theft relearn procedure. Hope this helps and let us know if this works and get back to us. Thanks for using 2CarPros.

theft light flashes continuously after turning off ignition. Vehicle starts and drives fine however can't seem to reprogram remote lock fobs. Is this normal? No check engine codes and have found nothing in manual or on google about this one way or the other

the only way to programme fobs or diagnose faults on the PATS system is via ford's diagnostic computer or equivalent

Thanks for the reply. I'm trying to program the door lock remote--it is not responding under the method by ford and the usual on-of eight times to access program mode is not working. I'm not trying to access the PATSII system but I'm afraid that it's causing the problem.

Is this the same was as you are trying .. you have to follow it step by step to the letter or it will fail to reprogramme .. and you MUST wait the 5 minutes at the end !!

Thanks Dave,
I'll try the sequence tomorrow. I'm not at the truck now so I'll have to wait. The only thing I see different was the previous instruction I was following stated to hit the unlock button in the vehicle first then start the on-off sequence to access programming mode. I never got to programming mode so that may be why.
I'll let you know what happens.
Thanks again---you've been more than helpful

How do i bypass Theft Protection on my 2001 truck listed above.

Unfortunately you are not able to bypass it. The system was built to not be able to be bypassed or someone would be able to easily steal your vehicle.

So that leaves us with two options. First, we can figure out what the issue is with your system and fix it.

Or you can find a company that offers a system delete module. Basically the PCM has the system deleted from it so that it does not wait for the authorization to start from the theft system. I have not had success with these modules as others have used them and then need help fixing them but others have said they work fine.

I would suggest we start with scanning for codes and finding out what the issue is and go from there unless you already know what is wrong and do not want to fix it.

Let us know and we can go from there. Thanks

I don't have the key for the truck so i used a screw driver to try and start it. all i am trying to do is make sure the engine runs because I need to take it out and put it in my truck.

Okay. So you are just looking to use the engine out of this truck? If that is the case then you don't need to worry about the theft system on this truck because all that will stay with the truck. The engine moving over will be wired to its new truck and that security system will have to authorize the security system to start the truck.

Or are you trying to get it started in this truck to make sure it runs before you put it in the other truck? If that is the case, I am not sure that is going to work. You need the PCM to fire the injectors and plugs and that will not be unlocked unless you get past the security system and that is not going to happen without the key. There are a lot of people online that say it can be done but I never found any that don't have a scantool that can wipe the keys or us a kit to bypass it which is what I was talking about earlier.

So if you are trying to do this, I guess we could try and get it to run as if it were on an engine stand.

Let me know your needs and we can try and figure something out.

Yeah, i just wanted to make sure it runs before I go through all the trouble of pulling it out. how would you do it as if it was on a engine stand?

The more I look through this, we just have to get the PCM unlocked through the security system because even if we put power to the PCM it is not going to fire the injectors or coils unless they are unlocked.

I think the easiest thing would be to get a key cut and programmed to the truck. Unfortunately there is just no way that we can run this on a stand without getting that PCM unlocked so that PATs system is going to be included in it or we need a PCM that doesn't require that system which is something you would have to buy and a key is much cheaper.

What if I took the PCM and the sensor that is in the steering column and key out of my truck and put it in the other truck?

I suspect once you get the engine in the other vehicle that you are going to have use the PCM as the one in the older truck is not going to run this new engine as they are different. So the more that I think through this entire process rather then just getting this engine running, the more I think you are opening a can of worms.

It can be done but this is going to be extensive. You are going to have to move over the wiring harness, sensors on the 5.4L, PCM, and theft system. So most people that do this, don't mess with the theft system because it is not the easiest to move over so they get an unlocked PCM for the vehicle that does not require the theft system.

So I don't want to tell you to get that PCM just to test this engine to get it to fire to see if you are going to use it but I don't see any other way given these circumstances.

Recently while attempting to start my truck to go to work the engine would turn over, the theft light would flash and the motor would never start. I have 2 key and it happens with both. Do I need to replace the ignition? :?:

Do you think someone attempted to break into your truck? sometimes if for some reason the truck belives it was an attempted theft it will shut everything down and you will have to put in a certian code to get it running again.

Ford finally notified me of the problem although it took them 3 days to figure it out once I told them what I thoutht the problem was.. Turns out to be the computer chip (transcriber) in the ignition that is worn and has to be replaced. This is the chip that reads the keys chip. I thought that I would add this just incase anyone else comes up with this problem.

Thanks

Thanks for your responce. good luck and dont forget to come back if you ever need anymore help!
