remote start, 2004 isuzu rodeo

Ok guys i bought a code alarm a670 i have it all in stalled and every thing works perfect except the remote start i can't get it to even attempt to crank the starter the only way it will ingade the starter is if i turn the key to run.. with out the key all it does is turn the acc's on and then back off when the start fails... I have a 2004 isuzu rodeo, and i have the dei universay bypass with a key installed in it, I also need some help installing that in not sure on the antenna pice wheather i can tap into the existing 2 wires coming from the key or is i need to put that ring arounf the key or what the ring is kinda big. so any one that can please help me out with this once again installing the bypass model and what im missing the reason the starter wont even kick in even with the key in the ignition.

i do i have a 556u in there dei but im not to sure of how to hook it up to the ignition, plus i must need to hook up another wire cuz even with the key in the ignition it can't cracnk the starter untill i turn the key to run then the alarm can crank the starter and start the car..

It sounds to me as if you may have a wire that is supposed to be fed by a constant hot being energized by a wire that is a switched hot. As far as the bypass is concerned, does the vehicle start and run when the key is left in the on position? I would recommend gettting the remote starter working when you leave a key in the ignition before troubleshooting the bypass module.

For a test, run the constant hot inputs to the remote start directly to the + battery terminal, fused at the battery. Then retry the unit, with your key in the off position but in the key cylinder.

Actuly i got it finnaly I did have 2 of the ignition wires backwords. i swapped them around and it cranked and putting in the by pass was a breeze, heck i even got the 2 step door locks working, rear defroster, horn and headlights so every thing is hooked up now and working perfectly I think my next task will be a window moduel..  thanks for the help guys..
