Hello, so it started fine before the windshield was replaced? Does the check engine light turn on when the key is turned on and if it does, does it turn off when cranking the engine?

I switched rr mirror back to original. Dono if it had a sensor in it
Auto Mechanic: Gene, Auto Service Technician replied 8 months ago

Ok so the light works, so the PCM power relay is working and the powertrain control module should be getting power since the relay is working( It turns on the engine light when the key is turned to on). When the pcm gets an rpm signal it turns the engine light off when cranking. Do you have fuel pressure at the fuel rail? You replaced the front windhshield? You said you have injector pulse, you have spark? Will it try and start if you spray carb cleaner into the intake? The anti theft light flashes when the key is on?

Ok which light is flashing the red THEFT lamp is flashing fast when the key is turned to the on position? Your scan tool will not communicate with the pcm, but it will power up off the data link connector, pin 16 on the DLC has power?

Red lite flashes fast on on pos my scann comes on but cant get any info or do any test. Its a snapon solus
Auto Mechanic: Gene, Auto Service Technician replied 8 months ago

Ok im sorry but im a little confused. Just to clairfy. The red Theft lamp is flashing fast when you are turning the key to on. This means there is an issue with the PATS key not being read by the security system. But im more concerned that the scan tool cant communicate with the vehicle. Will it work on another car if you try it. You said all fuses are good, you are powering the scan tool through the data link connector or through a cigar lighter/power point? You have power to pin 16 on the data link connector?

No 16 is that the bottom rt yes batt voltage
Customer reply replied 8 months ago
Tried another scanner. No comm either
Auto Mechanic: Gene, Auto Service Technician replied 8 months ago

Ok I will opt out then, it should communciate with pin 16 hot and the check engine light working. Another expert may be of more help to you.
