I have the alarm system hooked up, i have the remote start hooked up as well but its not turning over and starting the car. it flashes 7 times, (parking lights) do i need to install the starter inhibit relay?

The seven flashes of the parking lights when you attempt to remote start is the tach signal not being programmed. If you hooked up the tach wire already, turn the ignition on, press and release the programming switch three times. Turn the key off, press and hold the programming switch and start the car. Continue to hold the programming switch while the vehicle runs. The parking lights will be flashing while the tach is being programming. Hold for at least 15 seconds for a good signal. This allows the engine to "smooth out" into a normal idle rpm.
If the parking lights are not flashing, the tach is not being programmed. You may have skipped a step during the set up for the programming or, you have the wrong tach wire. If you went to a injector or coil wire, it is the uncommon wire. This means that there exists two or three wires at the injectors/coil packs. One or two of the wires are the same color at all of the injectors/coil packs and one wire is a different color at each injector/coil pack.
