Engine will turn over (cranks), but will not start (run). It has randomly started once or twice. I have good fuel pressure. Changed both the crank and cam sensors. Upon connecting my scan tool it will scan all modules by itself, and the only code it shows is P1000. Incomplete monitoring more or less. Now when I self test the modules by their self I get one DTC that I cannot clear, B1845, ignition tamper CKT fail in the Central Security module. When I run a live data stream I have a "IGNTAMSEN" that shows out of range. I would think the two related. I am unsure what exactly IGNTAMSEN is and its location. Also, I would think the "theft" light would be flashing with those two items and the theft light does not. I have also programmed two new keys to the truck after it quit running. Further information: I have No injector pulse or spark. The cop's have power to them but no GND pulse. Theft light comes on when key is turned to run. Goes out after 3 seconds and stays out. Flashes every 2 seconds when key is off. Any ideas or direction to go with would be great.

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.

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.

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 !

PROGRAMMING
REMOTE TRANSMITTER
Cycle ignition key 8 times within 10 seconds and end in RUN position to enter program mode. Doors should lock and unlock to confirm program mode has been entered. Press any button on transmitter(s). Doors will lock, then unlock to confirm being programmed. If doors do not respond, press button again (3 times maximum) with same transmitter. If doors still won't lock, go to SYSTEM TESTS. Repeat procedure for additional transmitters (4 maximum). If equipped with memory seats, ensure transmitter(s) are programmed in order according to numbers on back of transmitter(s). Turn ignition off or wait 5 minutes for system to exit program mode. All doors should lock, then unlock. Recheck system operation.
