95 taurus wont start

I have a 1995 taurus 3.0. Just installed a Bulldog Remote starter on it on Sunday. I had no problems at all. Tuesday Morning I started the car with the remote no problem. 10 minutes later I went to leave and the car had quit running. I could no longer start it either with the remote or the key in the ignition. Starter turns over just fine with the key. At first I thought it was the fuel pump relay... but I can hear the fuel pump kick in. When I turn the ignition key to start... the dash lights flash like the security system is acting up.... I have looked for loose connections with the Bulldog unit with no luck. Any ideas??? Thanks for your time. Tim

bulldogs are JUNK, i do this for a living, i work at best buy and we WILL NOT touch those. they are made very cheeply and they set on the shelf so long the brains go bad. i would allmost be willing to bet your brain is bad. hope that helps.
