remote start issue

My car’s a 98 pontiac grand prix GTP.  I have a Viper 160XV remote start and alarm.  Its been working great for over a year now.  I didn’t use solder, but mainly used wire crimps to tap the ignition/starter/(un)lock wires together.  I have the module just under the carpeted area near the hood latch/button.  Just yesterday after watchin Oceans 13 I went out to my car and pressed on my remote to activate the cars ignition.  It was raining and I accidentally left my windows open a bit.  Nothing started and when I pressed the unlock button still nothing.  I then noticed the LED light was on but very dim(suppose to be blinking to show its working. 

After turning the key and starting the car the LED was showing full bright.  I tried pressing both lock/unlock but the alarm/horn didn’t activate.  So I decided to unplug the main/primary wiring harness on the module just in case.  This morning I decided to see if I could troubleshoot the problem.  I double-checked to ensure no fuses were blown and they’re all OK.  I also made certain the ground wire off the primary harness was still being grounded and it is.  I then decided to replug the primary harness but when I did the module made the starter run, but the ignition was not being activated, so the starter was basically just running by itself.  When I noticed this for the 3-4 seconds I quickly disconnected the primary harness.  I thought it’d be the tach wire but its still tapped, with wire crimp, behind the dash overlay.  I then looked under the dash, and made certain all the wire crimps were tight and they appear to be.  I then unplugged the remote start ribbon harness off the module and replugged the primary, the starter didn’t turn on.  So I know it might have to do with either the remote start ribbon or the heavy gauge relay satellite that connects to it and also goes to the wiring harness on the car. 

My question is, why would the starter want to turn over when I would try to reconnect everything-remote start ribbon into module-but not have the ignition come on as well?  Im at a loss now, and I am in need of some serious help.  Thanks in advance. 

Btw the module didn’t seem to be wet from the rain, but when I was driving the car yesterday b4 unplugging the primary harness, I belive I heard a distinct ‘foil scrapping’ sound coming from the module, and I think a live wire was touching the chassis causing spark.  I don’t know for certain, just an assumption from the sound.  When I stopped the car, and checked I heard nor saw anything unusual.  Sorry for the long story. 

You sound like you're determined, so I'll give it a shot. dei units are known to crank the starter when you plug in main harness with all the fuses in. Same with if you disconnect the positive post of the battery and reconnect, the unit will attempt to start and keep cranking, so this was probably a fluke. As far as your dim LED light, this right here signifies something is definitely wrong. Ground is the first thing tech support will tell you to check. I recommend using the factory ground wire and tapping into it. If this doesn't fix your problem, start systematically eliminating your "crimp connectors" I assume you mean t taps "I didn’t use solder, but mainly used wire crimps to tap the ignition/starter/(un)lock wires together" and put the wires copper to copper and use 3m 33+ tape to wrap them tightly. This car is one of the easiest remote start installs out there and 80% of the wires are in the ignition harness, just clean the stuff up and you will find that one of your crimp connections that appear to be good aren't. Hope it doesn't burn down.....
