omega rs 7ks

Hello guys. I need some help. Ill try to explain as well as I can. 2006 ford ranger plain truck. No locks no nothing. I installed. A excalibur omega. Rs-7 on it that I've had new laying around for yrs. I used a wiring diagram. From this site. Helped a lot!!!! The starter will start the truck then runner for a few seconds then shut off. Seems like it runs till the high idle settles. Down then shuts off. I used a basic set up power, ground, starter, hood pin , ignition, accessory. ,brake pedal, engine detect smart start. Have not hooked up parking lights yet.that is all I know please help. Thanks Robb

It definitely sounds like the RS doesn't know the vehicle is still running. Although I am not familiar with that piece, you mention "engine detect smart start". I assume this is their version of virtual tach or similar. Hook up the tach wire, reprogram and report back. Tach connections are the most reliable way.Installer, IT support, and FFL. I need less hobbies.
