Ford Super Duty (1999-2016) :: 2008 Truck Will Not Crank Over - Anti Theft Light Blinks Rapidly
Sep 9, 2015
I have a 2008 F-350. The Anti-theft light blinks rapidly and the truck will not turn over. Give it some time or take the key out of the ignition and in repeatedly and it will start. Sometimes not till the next day. I have replaced the transceiver & key. Did not fix the problem. Dealers all say: they have never seen this before. I would like to just bypass the Anti-theft system if possible. There are times I will just let it run for hours not to be stuck.

My Ford 250 Super Duty, it is a 2008 model. I can't get it to start and the anti-theft light keeps blinking. At least i think it is an anti-theft light, a blinking red lock on the instrument panel. I bought this truck from an auction so I don't have a manual, neither do I have a key set with the push button stuff on it. Just 2 electronic keys. Someone suggested unhooking the battery overnight, and someone else suggested pressing the valet button. I found a button under the dash, I have no idea if it is the right one.

I was just wondering how you fix the theft light on top of the dash. I gotta 07 Lariat Diesel but the light never blinks no matter what I do? Is it possible it is burnt out? If so how do I go about replacing it? or could it be a fuse?

I have a 2000 EX V10 100K miles. Saturday my anti theft light started blinking rapidly and the truck would turn over but no fuel. No check engine light. Fires up if I use starter fluid. I have read online alot about PATS systems and keys so I tried my extra key.... Did not work. I am planning to try syncing the key with the truck again today. Whats next? I checked all fuses twice. I saw somewhere about the ECM? Might have an issue?

I just got an 08 F-150. No key fob and no power locks but it does have what appears to be an anti-theft device that blinks on the top of the dash. I would like to have keyless entry. What steps should I take?

I was driving down the freeway the other day and when I hit a rough patch of road, nothing major, the truck sputtered and the 4x4 Low light blinked a few times on the console. I was driving in 2wd at the time. I kept driving and every bump I hit the truck sputtered as though trying to shift and the light blinked. On smooth road it didn't happen.
Today I drove to work at 6:30AM (40 miles), no issue. At noon I drove home and the issue started again. Every bump I hit the light came on and the truck seemed to want to try and shift into 4x4 low.
I got home, parked the truck for a few hours, then went out again, no issue. But about 20 minutes later it started again. I pulled over shifted to 4x4 high, drove it, was fine, went into 4x4 low seemed fine, went back to 2wd drove it some more issue came back. I've read tons of online threads regarding 4x4 lights etc, none like this and none on F250 Super Duty (2008).

I have an issue with my 2008 f250 6.4 where the gauge cluster is dark and truck won't crank. The only light on the dash is the airbag light. I have tried reprogamming with my Spartan tuner, checked fuses, removed aftermarket alarm, charged batteries. I scanned and got two codes. P1260 theft detected and a u code no comm with cluster.

I have looked through a ton of threads to see if I can find one similar to my problem but have not. I have stock setup but had a dealer installed anti-theft device. The first time it would not crank, it was like the the anti-theft plug was missing so I checked out the key, tried the spare and finally removed it all together. I checked all the fuses and swapped the Starter relay for another of the same part number.
I later sifted it into neutral assuming it was the P/N Switch and it started. This continued intermittent for several days but then Neutral wouldn't work. I got under the truck and pushed on the actuator rod for the transmission and it started again for a few days. If finally failed again and I had time to buy a replacement switch.
Once installed I verified I had back up lights in reverse but still no crank. I have since pulled off the starter and had it verified as good. Is there more to setting/adjusting the neutral switch or is there something I am missing before I tow it in?

1999 f150 4.2l v6.. The anti theft system has kicked in and my truck won't turn over, the stereo won't turn on, the lights don't work. How can I fix this?

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 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.

ive got a 2000 v-10 excursion with 111k. Never had a problem like this before but last week I was driving home an noticed the theft light blinking while I was driving. Got home shut it off. next morning went to start it and nothing! when the doors open it makes a clicking noise under the dash. if I jump it the truck will start right up. If the batt is disconnected them re-connected it will start once until turned off and then nothing until its disconnected again. I ve got an elk hunt in 2 weeks and need to figure it out!

2013 F250 6.2, 71500 miles. Airbag light comes on and stays on steadily, no blinks so that I can read the code. Any way before I make the dreaded trip to the dealer?

My father-in-law has a 2008 f-250 with the 5.4. as he was driving a while back all the gauges of the dash quit. The engine still kept running without any noticeable difference but when he shut the engine off and tried to restart, it wouldn't even crank but the security light was flashing. He tried starting it again a few hours later and it started just like normal and ran fine.
He has had this problem occur several times in the last few months, but the other day it repeated the problem again and would not restart for about 5 days. He has tried charging the batteries, changing relays, checking all fuses and finding none blown, scanned it with his code reader, and checked the steering column for bare or rubbed wires.

Last night my truck wouldnt start. Drove fine all day, started up bunch of different times. Went to go home at night. No crank, everything else works, hear the fuel pump prime windows radio everything. smacked the starter a few times but no change. Checked the fuses and relays, all appear good. So im guessing the starter or the starter solenoid, but I cant find one on the truck just something that looks like it could be it attached to the starter.

I'm having a strange issue with my 2008 F350 6.4. I have only had this truck for about 2 months now. Every time it gets wet (from rain or a carwash), the 4x4 low light begins flashing, and the truck surges badly at low speeds. When I get above about 25 MPH, the light stops, and the truck runs normally. At the next stoplight, it happens all over again. After a couple days of dry time (?), the truck is back to normal (until it gets wet again). I have found a couple of old threads involving some similar symptoms, but they were never resolved on this forum (that I could find). I believe the transfer case selector motor has been replaced at some point, as it has a Dorman brand sticker on it. I wouldn't think Ford would use Dorman parts as original equipment.

On my new/used 2008 Escape XLT 2.3L 2WD. It flashes every two seconds, like the manual says. Lower left corner of instrument cluster.
But I don't recall the warning light flashing when I test drove it. But I did push the buttons on the keyfob and various places on the dash/instrument cluster to see what they did...
Is the anti-theft system an on/off affair? If so, how do I turn it off?

I'm having a problem with my 04 f250 6.0. I replaced my brakes rotors and calipers yesterday along with my fuel filters and after I took out my air filter to check it and put it back in my truck will no longer crank. When I put my key in the on position all of my lights and dings happen but I don't hear my fuel pump and when I go to turn it over I get nothing at all.

Last night it was surging at idle and then just died. It had a code on it about the crank sensor not communicating... no codes this morning and it wont start.
I just bought the damn thing 3 weeks ago and its already not running. Where do I start to diagnose this damn thing..........
