Hi all new to the site and new GT owner,, I bought a 99 GT about 4 days ago was driving down the road and the car died out ended up having to get it towed home, the Anti Theft light is blinking at first started reading about it I thought it was the PATS system but further reading made it seem like the PATS wouldnt cause the car to die while driving down the road, I have tried all the Internet fixes I could try from the internet, it cranks fine but doesnt seem to be fireing also there is little to no preasure on the fuel rails, any help would be great, Thanks for any help. Forgot to say the anti theft light blinks 1 the 6 error code

Very first thing. Have you reviewed the battery and alternator?

Please review the "1996+ Crank with no start check list " and post the results.

With all the tests in the crank with no start check list, ^^ this is all that you did?

Does the fuel pump "prime" at initial key on?
