When you say that it doesn't crank, do you mean it will not even activate the starter solenoid ? If so, you have a wiring issue but if it turns over the starter but doesn't run, then it's a tach issue or an Immobilizer issue.Jeff

Velocity, Yes, It won't activate the starter solenoid. The instructions on the DEI 555f says to hook up all the wires for the remote start before you install the By pass module. I've Got 12v constant Ignition 1 and 2 Starter I just need it to crank but it won't crank at all... I've got Different Wiring codes.. And both are different. I Tested all the wiring Constant True IGN 1 True IGN 2 Starter Got it all hooked up.. Don't seem to Get it To crank.

if you indeed hooked up all the correct wiring, then you should be able to use these same wires and hot wire the car to start it, right? if you are unable to hot wire the car with those wires that you've chosen, then they're not the right wires....period. remember, a remote starter is just simply trying to duplicate the effect of you turning the key to start the car. btw, there's a few of other things that you'll need to check.....is the hood pin wire receiving a ground signal somehow? howabout the brake wire....is it receiving +12v somehow? are there some programming features that need to be done first before you can remote start? good luck

I had this same problem. Turns out I had the start wire from the remote start on the wring side of the Starter Kill/Anti Grind Relay.itmdtr

I had this same problem. Turns out I had the start wire from the remote start on the wrong side of the Starter Kill/Anti Grind Relay.itmdtr

I don't have a starter kill relay. I wired it directly to the starter wire. My starter wire is Blk/wht. Anyone has another wiring diagram for this car.

That car has two starter wires: GREEN/ YELLOW is starter #1, BLACK/ White is starter #2.itmdtr
