Electrical problem
2000 Ford F150 6 cyl Two Wheel Drive Manual 180k miles

My truck has a ghost in it.

Example: I start my truck like normal, drive (times/speeds vary), stalls, won't re-start in motion with key, won't "pop-clutch" start, park on the side of the road, won't start for 15-30 minutes (starter turns engine over, won't run), miraculously, after waiting, engine fires up, drive home, search for help online.

Given: Has PATS "C"-type (?), VIPER alarm (not remote start or 2-way), just replaced battery (3rd or 4th in lifetime).
Do you
have the same problem?

With two alarm systems, or to be more precise, anti theft systems, what does the light on the das (factory) do when it's not starting> With key removed, it should blink once every 2-3 seconds, key on "on" it should go out, this means it's now able to start, ANY other position, acc, off, or key out, light should blink, what's yours doing?

My "THEFT" light on my dash flashes aggressively (about 3 times per second or faster) when the truck stalls out AND when it doesn't start up.

Be aware that the new PATS system types B and C (on the following chart) offer an anti-scan feature. If you are trying to start a vehicle with an unprogrammed PATS key, the Theft Light Emitting Diode (LED) will flash rapidly and the vehicle will not be able to start. In this case, leave the key in the run position for 30 seconds for the anti-scan feature to time-out. The vehicle would still fail to start even if a programmed PATS key was attempted to start the vehicle within this 30 second window. The status of this feature can be checked by observing the antiscan PID under the PATS, HEC, or VIC module selections.
Your key may be defective, a trip to Ford for new programmed keys will help, but try starting the truck, leave key on on position for 30 seconds then start it.
If you have two good keys, you can program them again like this: KEY PROGRAMMING USING 2 PROGRAMMED KEYS 1. Insert first programmed ignition key into ignition lock cylinder. Turn ignition switch from LOCK to RUN position (ignition switch must stay in RUN position for one second). Turn ignition switch to LOCK position. Remove ignition key from ignition lock cylinder. 2. Within 5 seconds of turning ignition switch to LOCK position, insert second programmed ignition key into ignition lock cylinder. Turn ignition switch from LOCK to RUN position (ignition switch must stay in RUN position for one second). Turn ignition switch to LOCK position and remove second ignition key from ignition lock cylinder. 3. Within 5 seconds of turning ignition switch to LOCK position, insert a NEW unprogrammed ignition key into ignition lock cylinder. Turn ignition switch from LOCK to RUN position (ignition switch must stay in RUN position for one second). Turn ignition switch to LOCK position. Remove ignition key from ignition lock cylinder. The NEW ignition key should now be programmed. To program additional ignition key(s), repeat ignition key programming procedure from step 1.
NOTE: This procedure will only work if 2 or more programmed ignition keys are available and there is a need to program additional ignition keys. If 2 ignition keys are not available, perform ERASE ALL KEYS & PROGRAM 2 KEYS. PID SPARE_KY must be enabled for this procedure to operate. To enable this PID, perform ENABLE/DISABLE SPARE KEY PROGRAMMING and enable spare ignition key programming switch. If programming procedure is successful, new ignition key(s) will start vehicle and THEFT indicator will illuminate for 3 seconds. If programming procedure is not successful, new ignition key(s) will not start vehicle and THEFT indicator will flash. If necessary, repeat programming procedure. If programming of ignition key(s) is still unsuccessful, perform procedures in SELF-DIAGNOSTIC SYSTEM. Maximum of 8 ignition keys can be programmed into system. If procedure is not performed as outlined, programming procedure will end. Ignition keys must have correct ignition key cut for vehicle and must be an encoded ignition key.

I was under the impression that after a few seconds of running, PATS doesn't check for the key's code. If that's the case, even if I have a defective key, it will start and drive, and never die on the street. If I stall again, I will try your suggestion (and I could use an extra key). A couple days ago, I tried draining any natural memory by disconnecting my battery all night. Since then, it hasn't given me any problems. Do you think that natural memory in the computers could have been the culprit?

Fords have keep alive memory, and if a problem is repaired, this has to be reset, or the sysmtoms may persist, so it is possible.

So, with your second post, you're saying I could start my truck with a simple, metal-headed key as long as it's in the RUN position for more than 30 seconds?

On your 3rd post, "if a problem is repaired, this has to be reset."
Do you mean that my ECM has to be re-flashed, then reprogrammed for another set of keys?

Only if it has a remote start. This would require a good transponder key be in the starting circuit, that's done with a small box the key goes into and it reads the key as power is turned on by the remote starter. I am saying even though it may not think your key is the right one, it takes 30 seconds wait time before it will start even with a good key once the security light is flashing rapidly.

Ok, I see what you're saying, it's a 30 second lockout.
So I'm probably looking at getting 2 new keys programmed (for about $120, since I have just the one key) and if that doesn't fix it, check the PATS system for errors, then possibly re-flash the ECM?

If you have only one good key, Ford will charge for the two keys, I paid 21.00 each for Lincoln keys and programmed them with the above method, but because you only have one key, the NGS super star tool is needed. Add 1 hour labor at Ford!
