can't get to codes
i have a 96 xlt 5.8l When i try to crank it up it won't fire if I cycle the key 3 or 4 times it starts and runs good. i replaced the pressure regulator and didnt fix the the problem. check engine light came on so i picked up a Hanyes manual went through how to retrive codes it showed where to place jump wire to start koeo test i found the STI connector but can't find the DLC connector. If there is any sugguestions or hints i could use a little help.
