car was stolen , they broke the ignition & removed the pass key 3.
I replaced both , now it starts runs 3 seconds , and stops .
Starts again runs 3 seconds and kills itself over and over same thing.
When I 1st put the key in it dings 5 times then 3 times and 3 times and 3 times .
The security light is on solid the whole time . It never flashes. I replaced the PCM Inside
The air box twice. And the ignition and the pass key 3 .
How do I get it to run more than 3 seconds ?????

take it to a garage and let them set the security system with a scanner the keys are not coded to it. that is why it runs like it does.
