My 1999 windstar has a theft light blinking on dash after changing battery turns over but no fuel how can I reset this

this will sound odd, but I was having the same issue, and I tried everything on this forum but I wasn't getting anywhere, but I decided to check all my fuses under the dash and found out on my 2010 Ford E350 fuse #54 fuel pump relay coil, was blown, I replaced it and the van started right up, I was having all the issues of a PAT system failure, dash lights on, security light blinking, and advance track service light on.

The problem may not be with anti-theft but with a bad fuel pump,cam/crank sensor etc. Also, you may try unlocking the drivers door with the key. On most cars that is the standard method for disabling the security system.

at the dealer

u have triped the anti theft and may have to go as far as puttinig old radio back in

Could be fuel pump. If you hear the pump in the rear of the car turn on and then quit you may have a theft system problem. Check on the dash for the theft system indicator. If it is blinking when you try to start the car that is the problem. Close all doors and turn key to On for 10 mins til theft light turns solid and disappears. then try to start car.

did you try to remove both battery cables for about 10 min or so ?? that may reset the comp and clear the problem

this is one way to reset it :
first make sure the battery is fully charged , then do the following:
key in the ignition but do not crank the motor, just leave it at the
ignition mode for ten minutes ,then turn it off POSITION for 5 seconds then REPEAT again 2 more times. at the 3 rd time youre gonna notice the ANTI THEFT light on dash to blink. when doing the last step , remove key , inserted again and turn on motor , good luck , AJ

my 2001 ford windstar wont start, i was driving it and completly lost power it would chug like it was running out of gas then had no power,shut it off and it wouldnt start again after that.I changed the mass air low censor,the fuel pump,the ignition switch,relays and fuses the brain box,i have no idea what to change next have any suggestion that could help that would be great thanks

Something in your anti theft system has failed. The key,transceiver, or module. The only way to find out is to run a diag on that circuit. You will need special tester.

The taurus is equipped with what is called a PATS (passive anti theft) that wont let the car start until it recognizes the key in the ignition, some things to check, first when you put the key in and turn the car to run (not start) does the theft light blink fast in the dash or is there a red on light on the dash that starts blinking? if so it is a PATS problem, the only ones I know of that can program keys are dealers, if the car wont turn over it probably is not a fuel pressure issue, the most common thing would be the PATS keys either unprogrammed or somthing wrong with the module. hope this helps
