Crimestopper RS999FMTW1 Install Problems

Hi   I am having troubles with a RS999 FM TW1  I have it installed in a 2000 Dodge Durango 4.7 liter w/ keyless entry but w/o factory alarm.  I have hooked up the wires according to the Crimestopper techweb wiring color codes.  The remote worked fine for 2 starts and then would start sporadically and only with the one way remote.  The techs at Crimestopper told me that they had some problems with the 2 ways not wanting to shut off and running down batteries.  They also told me to re-learn the one way  remote, which I did and the unit does accept the remote but just will not do anything.  Sometimes the remote works and other times nothing at all.  It almost acts like the antenna is not working properly. 

Any help would be greatly appreciated.  Thanks

Yes I have checked all connections three times.  Thing is the unit will re-learn the one-way remote but it will not do anything after that.  I thought maybe I was in valet mode but have checked and re-checked that also.  I still feel that the antenna is the culprit, but here is how I have it wired:

• 12 volts +  ----- + Battery (both red wires)                                                                                                    
• Ignition 1 ------  Dark Blue - Pink
• Ignition 2 ------  GREEN/ red - Pink/wht
• Accessory ----- BLACK/ orange - Gray
• Starter ----------  Yellow - brown
• Black (ground) from module on bolt on firewall
• Brake pedal wire is hooked up

I have checked all wires using a DMM and can not find anything wrong.  This isn't my first time installing a remote but first time with crimestopper

Thanks

Just another thing to think about.  I unplugged the box from the harness and let it sit out overnight and when I put it back in the next day it worked fine for a couple of times again!!  Just a question,  is there a possibility that I am not showing a big enough drop in voltage to prove to the unit that the truck is off!?? I know I am probably just grasping at straws but the website had where you hook 12V constant to 2 wires in the harness but the installation guide said to hook directly to the battery (recommended).  If I change it to tach mode will that help? 

Thanks again everyone.

Thank you everyone !!  This place is great!  I did find the trouble and it was where I had my 12 volt constant wires.  The Install book tells you to install both wires directly to the battery, while thier wiring diagram you get from Crimestopper says to hook them to wiring harness.  Tried battery first.  Changed those to under dash and it starts everytime. 

Thanks
