Remote starter cranks but doesn't start!

I've had the remote starter on the car for 6 months working fine.  The dealer fixed my loose stering wheel and ever since then my remote starter doesn't work.  I had a fight with the dealer, they won't fix it because I installed it myself.  I checked for loose wires but couldn't seem to find any.  When you press the button the car turns over but then doesn't catch.  It tries several times, but always the same result, no start!  The car is a 2000 Cavelier z24, it starts fine without the remote. I have tried resetting it, again with no luck.  The dealer had problems with it because the called me to tell me the car was messed up and that the lights, or the heater didn't work.  They fixed that but that's it.  Any info will be greatly appreciated, I live in Canada and winter has arrived. 

Thank you

Actually I didn't get a chance to look at it again.  I will tomorrow.  I did notice one problem which may help narrow it down.  To program options on the starter/alarm you put the key to the "on position then press whatever button on the remote to active/disactivate a feature.  Well when I press the #2 button  4 times with the key "on" this turns "chirps" on or off.  But now if I press the #2 button 4 times without putting the key  "on" it still turns chirps on or off.  So it is as if the key is always "on".  No lights stay on, on the dash like when you do turn the key "on" though.  I think it must be either the ignition in the wrong place???

Any comments would help

Thanks
