791xv on 2001 suburban

Well the first poblem is i cant get the remote start to work. Nothing happens. When you hit the star twice nothing happens. I have everything hooked up right I think. I used the 555l and hooked it up like it said. Also to use the factory disarm wire do i have to use a relay. I hooked the tach wire to the ecm like it said pin number 10. I hooked in the heavy guage satelite pack. I hooked the starter wire up to the right sides. i also hooked up the pink/white to the 2nd ign wire. Is that necessary. What wire do i hook to the 555l blue wire. I used the blue wire from the satelite output harness the four wire one.  What do I do with the whie/blue wire from harness 1. And do I ground the hood pin wire off. Do I ground the brake shut down wire? Alarm and keyless work fine just having probs with RS and factory disarm. The factory alarm goes off when I hit the unlock button the 791. thanks for any help.Ace Customs

Hoodpin cannot see ground, it should ground with the hood open which will disable the remote start feature. Brake wire should go to the positive side at the brake switch. The brake wire is White at the brake switch and should show 12v+ when the pedal is depressed. Disarm wire is Lt.Green found at the keyless entry module and it is negative, no relay should be required. I know that doesn't solve your problem, but it might help. Some other ideas I do have but since I am unfamiliar with DEI products, I don't know if they will help: Some units require you to program the tach before they will attempt to remote start. The install manual will tell you this. I guess another idea would be to check if there is a diagnostic code that might tell you if something is wrong. The manual will tell you this also. Sorry I couldn't be of more specific assistence.J Rilla

you need to program the tach before it will remote start.

k i will try this and let you know what happens. Ace Customs

This is not a shot in anyway, but did you read the install manual. Every question you asked is answered in that manual. I would suggest mabye browsing through it again.double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer
