I didnt think I had a factory alarm either until I saw the OEM alarm module next to the DME in the passenger footwell. I did not have an additional keyhole in my door or any other "indicators" of a factory alarm. Are you absolutely sure?

I am getting spark from the coil when doing the test on Clark's. I have tried a good coil off a running car and still nothing
Sorry not understanding. First sentence you have spark but the second sentence you say you have nothing. Typo?

Try to run your resistance checks for speed sensor (confirm part number is correct) from the DME pins to eliminate any issues with the harness or plug. The speed sensor plug (up near the O2 sensor plug near the firewall) is prone to heat and can become brittle and crumble (mine literally turned to dust), so verify the readings at the DME, not at the sensor.
