Just finished installing a Compustar CS800s with a Fortin INT-SL. Everything was working good, but I started having issues where the car would not stay running when remote started. It will start, run for maybe 5 seconds, and then die. It will do that a total of 3 times before giving up. It doesn't always do it though. A lot of the time it will start and stay running on the first try. Not sure what the issue is here. I do not have a tach wire conencted since the Compustar claimed it was tachless sensing. Do I need one? If so, any clue where it is on my car?
