car not starting

i have a 1998 mustang gt 5 speed, car cranks but won't start,theft light for securilock is flashing, do i have to re progran key to start the car.fuel and spark is there, but car won't start. thanks. :mad:

Yea thats what I'm thinking. The keys have a chip in them, so if it doesn't think it is right then they will NOT start. It is to make sure that someone doesn't copy your key at TruValu or something. I knew a Grand Marquis that did the same thing. I think you need to check with your local Ford garage to fix it. Hope this helps.

you may want to make sure you have pulse .i have seen spark and fuel preasure but the injectors not work . usaully the control mod under the coil packs . a noid light will tell ya quick if you have pulse though
