Ford F-150 - 1997-2003 :: 2001 - Truck Won't Start - Anti Theft Light Flashes

My 2001 f150 is not starting up. The anti theft light flashes and then eventually slows down and flashes one time, pauses and then flashes two more times. The odometer still shows my mileage as I know some people with this issue just get dashes. I know there are passive anti theft codes that can indicate what is wrong but cant find a chart with any info for all the codes. I'm going to assume my pats transceiver module is shot. Or maybe the key simply needs to be reprogrammed? I checked fuses, relays, etc and didn't see any that were blown. What could be causing it? Or maybe there's a relay I forgot to check out.

Ford F-150 - 1997-2003 :: 2000 - Truck Would Not Start - Clicking Sound And Theft Light On Blinking

I just bought a 00 f150 4x4 with a 5.4 auto...it wouldn't start but not because something was wrong. it kept making a clicking sound and the theft light was one blinking...took my bronco to work and when I came home it started right up...I was thinking one of the keys didn't have the chip in it but it started with both keys....it doesn't have a key fob or keyless entry. I tried locking my drivers door with the key and unlock it...

Ford F-150 - 1997-2003 :: 2000 - Starting Rough Intermittently - Theft Light Flashes Once In A While?

I own a 2000 f-150 7700 series with a 4in body lift. recently Ive had a problem starting (I believe it is from the shifter not recognizing im in park) but now my theft light flashes at me and there is a weird sound that sounds like a relay from under my steering column when i roll my windows down, move shifter around or turn on 4x4. also my radio stays one every once in a while after the key is turned all the way back to off, and windows wont roll down after i hear the relay sound. Ive read to tighten shifter linkage and will do that tomorrow to see if that fixes it.

Ford F-150 - 1997-2003 :: 1999 XLT - Crank No Start / Theft Light Flashes A Code Of 1 Then 4 / PCM Not Power Up

I have an intermittent security system issue. I sometimes get a dotted line in odometer and rapidly flashing theft light.

Crank no start. After a time, the theft light flashes a code of 1 then 4. Research gives me the result that PCM did not power up.

Have pulled gauges. Fixed known cold solder joint issue. Checked all connectors and reinstalled. Truck starts fine about 7/10 tries.

I have replaced battery terminals. Removed cleaned and replaced all firewall grounds. Checked harness connection blocks and PCM connector. Made sure all under hood fuses and relays working.

Currently sitting in a parking lot waiting for it to decide to start again. Only one chipped key. Where to look next? 1999 F150 xlt 6 cylinder.

Ford F-150 - 1997-2003 :: Theft Light Is On And Truck Will Not Start

I did the power door fix, wrapping the door actuator motor 'resistor' in foil, and all was good. This morning I started the truck to move it, all fine, then pulled the door panel off to readjust the window guide in the door as windows were binding. After adjustment I went to turn on the ignition to test the window and the Theft light is on, and the truck won't start! It's a1999 F150, 5.4L.

1. The power comes on when I turn the key to ON, then when I turn the key to start the truck I hear nothing, no clicking, and the power goes off.
2. After leaving the key in the On position for 45 seconds, the Theft light blinks rapidly, the odometer is all dashes, the RPM and Speedometer gauges swing to max, then back to 0.
3. When turning the key to start the truck, there's a 1 click sound (solenoid?), then all power goes off on the instrument panel, no cranking.

What might have gone wrong here? Could the wrapping of the 'resistor' in foil in the door actuator have caused an electrical short? [URL] .....

Below happened previously but not any more...

4. When I turn the power back on to ON and push the buttons for the windows, the power seems to cycle On / Off in 2 second intervals, as the window goes down a bit, then stops, then goes down a bit, stops etc. and the lights on the instrument panel dim / go on / dim in the same cycle.

Ford F-150 - 1997-2003 :: Theft Light Flashes When Driving

I have a 2001 F150 4.2 V6. Three days ago, I noticed the Theft light blinking while driving. At first, there was no issues with performance, although the blinking was most noticeable just as I tapped the accelerator at cruising speed.

I thought it may temporarily disconnect the battery, which I did. After hooking it back up, I went for a test drive. About five miles into the drive I picked up an intermittent, though somewhat steady skip--almost like a plug wire. Shortly thereafter, the flashing light returned.

I'm not sure if the two problems are connected (the light and skip) or if it's just a coincidence.

Ford F-150 - 1997-2003 :: 1999 - Truck Won't Start / Theft Light Just Started Blinking

I recently changed the heater core on my 99 F-150 which meant i had to remove the dash. I got everything back together turned the key to start it and nothing it wouldn't start it wont even turn over. All the electronics come on like normal it just wont start. I have chased every wire every connection into madness. It has an aftermarket remote start someone said that would have bypassed the PATS but i dont know about that the theft light just started blinking.

Ford Ranger / B-Series :: 2000 Truck Won't Start / Theft Light Blinks

I just bought a 2000 Ranger. I bought it at company auction for cheap because it wouldn't start. The battery was dead when I got to it. I put a brand new battery in it since it has 155,000 miles. When you turn the key to the on position, the theft light starts blinking rapidly. It will continue to do so for about 45 seconds if you leave the key on; then it will go out. However, if you turn the key to start, all you hear is relays clicking. The engine doesn't crank at all. I jumped the starter relay and the engine turns over. I have the factory manuals for wiring diagrams and diagnostic procedures.

The theft system relies on trouble codes to point you in the right direction for testing. I borrowed an Actron code reader (like you get at Autozone) and it says there are no codes. I'm wondering, though, if it only reads the SAE standard codes from any vehicle and not the manufacturer specific codes like the theft system. I have gone through a few of the diagnostic procedures with a multimeter, but it's like looking for a needle in a haystack without the codes. So far everything I've checked has come back ok. Any common issues this might be related to? BTW, I've gotten bits and pieces of info about this truck from the guys who drove it. Apparently, it just wouldn't start one day and was parked for the next several months until I bought it.

Ford F-150 - 1997-2003 :: No Start Just Crank - Theft Light Blinking

i have a 99 f150 with a 4.6 that will not start. it has sat for a while now. when i go to turn the key to turn it on it cranks and cranks and cranks but wont start. the theft light blinks like crazy and the odometer reads dashes. There is also a relay which i do believe is the pcm relay that clicks like crazy. when the relay clicks and the key is first turned to the on position the fuel pump will turn on and off as the relay clicks.

We tried putting a scan tool to it to try to pull a code and the scan tool wont connect. I do believe its the pats system kicking, but i also think its related to this relay clicking like a mother, maybe a bad connection in the junction or something. But I am not really sure how to try to start and find the problem. i have also tried replacing the relay that clicks and the new relay does the same thing.

Ford F-150 - 1997-2003 :: ECM Changed But Still Won't Start And Theft Light Is Flashing

My alarm and lights started going off one night. By the time I got to it, everything stopped. When I tried to start the next morning, I got nothing. After several tries, horn and lights started again. The only way to stop it was to disconnect battery.

One person told me that it was the key or the ignition not recognizing the key. I was then told that my truck, 97 f150, had no chip in the key so the problem was the computer.

I replaced my computer with a refurbished one. Once I hooked up the battery, the horn was still going, lights flashing and theft light still blinking. Also, not sure if its related, but when I try to use the key in the passenger door it turns, but there is very little resistance and the door does not unlock.

Ford F-150 - 1997-2003 :: Code P1260 Indicating Attempted Theft Which Disabled The Truck

I have a 1999 F150 with a 5.4L. I recently replaced the PCM with a new unit from autocomputerexchange.net that was programed for my truck. I installed the PCM but the truck did not start. The theft light is also flashing rapidly during cranking. I ran a code scanner a recieved the code P1260 indicating an attempted theft which disabled the truck. I read that if you have two keys you can sync the keys with the new computer but unfortunately one of the keys stopped working a couple years ago (not sure why, stopped for gas and it never started back up). Since i do not have two working keys do i have to tow the truck to a dealer and let them reprogram the keys and reset the PATS or can i have a locksmith recode the keys and sync the keys myself.

Ford F-150 (2004-2008) :: No Crank And Red Theft Light Flashes

...Battery is very weak also but had a couple questions...

I started by reading up on issue and 9 times out of 10 people were saying the fuel pump driver module causes the issue...

So I ordered a Dorman and plugged it in...I did not bolt it down...Just wanted to see if it would fix and nothing...

Now stuck on the starter...Top bolt is a huge nightmare.

Would a weak battery and bad starter cause theft light to flash or is my problem elsewhere?

Ford F-150 - 1997-2003 :: 2000 Truck Will Not Start After Running For A While Then Sits For About An Hour

2000 2WD 4.6L ... I was trouble shooting why the truck will not start after it has run for awhile then sits for about an hour. I was checking the connections on the solenoid switch on the fire wall when my wrench slipped and touched both terminals on the solenoid and the engine starter kicked in. I tightened the connection then tried to start the truck with no luck. so I tried leaving the key in the "ON" position and jumped the two terminals and the truck started. Does this tell me I have a bad solenoid switch?

I was driving home tonight and stopped at stop sign. I took off and truck died and coasted to a stop. I tried to start but all it does is theft light blinks really fast and will not turn motor over. I tried to reset pat by following procedure I found on internet. Still no start. I then unhooked battery cables and left off for 15 minutes then hooked up but still no start and blinking theft light. I also tried spare key and still no start. What else can I do. I had it towed to place that just bulletproof my truck. Truck has been running great. I did not want to leave it on the side off road in the middle of country all night.
