Ford F-150 - 1997-2003 :: ECM Changed But Still Won't Start And Theft Light Is Flashing
Apr 11, 2016
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.

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.

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.

I have a 2000 f150 with 200k miles. I have no spark and no gas at the fuel rail Schrader valve. I have replaced the shaft pos sensor, no start. I have checked the fuses and the relays. I have crawled under truck and listen for the fuel pump to turn on while someone turned the key to on and heard nothing. I have 2 keys and while turning the key to on and start, the THEFT lite flashes. I have checked the impact sensor on the passing sick panel, it hasn't been tripped.

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.

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.

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...

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.

Same symptoms as last time : [URL].....
I did notice that the theft light is not flashing this time. Truck acts as if its not in park. I have wiggled the shifter, and even tried to start it in neutral with no luck. Im really thinking that it has something to do with the anti theft/PATS system.

My "Theft" light on my 2005 Ford Escape is flashing and I cannot start the Escape.
1. I tried the key that I had been using successfully for the last 7 years. , car did not start, Theft light blinked. ,
2. Tried wife's dealer key, Car won't start, theft light blinks.
3. Tried various things, such as manual locking & unlocking, turning alarm beeping on/off, disconnecting battery, etc. Nothing works.
Called the dealer, they say they know nothing. Must bring car in, they say. Basically I am screwed and now must spend big bucks to take it the dealer because of Ford's software bug.

My 2000 Explorer overheated and I had water pump and intake manifold replaced.. then it had a freeze plug rust out and its replaced, I'm holding water.. but now it just wont start.. we've tried everything from changing fuel injectors, fuel delivery unit on intake, now the fuel pump is changed.. still wont start and the theft light is flashing fast.. my dad changed computers while I was out of town,, is it the theft device or does the computer need coded for this explorer?? we have taken negative off battery but nothing.. And if I change the motor will that work or still not run because of theft light or computer??

How to reset the Anti Theft on my explorer? The light is flashing fast and the engine won't start. Without the anti theft being reset the truck won't start. Been checking around to find an answer but can't find one...

The brake lights on my '02 F150 have started flashing spontaneously ie - with no one in truck. This lasts for a few minutes, then stops, but can start again a few minutes later. The fear of course is that someday lights could come on and stay on, resulting in dead battery.
I do have a trailer brake controller that has been on truck ten years. Read something on internet that brake pedal switch might be going bad (??). Any one else observed this strange behavior?

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.

Left the truck sitting for a couple of months while working out of town. I bought this truck used with only 1 key. We rebuilt the engine and had noise issues so we don't want to drive it much until this is resolved. I went out to start the truck to move it and it would not start. It had cranked right up the week before. Now it just spins over and the theft light blinks rapidly. I've check all the door locks.
When I called a Ford dealership all the service guy would tell me is that it's going to have a new key made and I have to have the title on the truck to get it done. AND, I have to have the truck towed to a dealership to fix the problem of it not starting... The battery drained down so I took it out and charged it... only thing I can possibly think of is a low battery or maybe somebody tried to steal it while I was out of town and messed up something.

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.

So I noticed this is a common problem in several scenarios. Some are electric failures and key failures and computer failures....And other times they happen when you switch the cluster.
I had a blacked out cluster with a couple broken gauges and after spending an hour swapping the cluster I get a crank but no start. I tried switching the 301 and 304 fuses (fuel pump and PCM) as that was mentioned somewhere online but it did nothing. Any quick fixes or do I need to tow it to a dealership?

I have a 2003 Ford Escape Limited V6 replaced thermostat and fuel pump and 3 coils and 3 spark plugs recently. Now the theft light has come on and will not crank or start. The fuel pump is still not working unless I manually press the fuse under the hood which is also the only way the car will crank still will not start. That's because the previous owner got the key stuck in the ignition so he bypassed it with a dial you can turn. The dial will put the car into ACC and on mode but will not get the car to crank. Also btn1 and btn2 fuses under the hood are draining my battery.
