Fuel pump or factory immobiliser.

factory immobilizer is what my gut is saying, something about if the oem alarm is going off and the battery is disconnected it won't restart?

Is there a way to reset it?

if the factory immobilizer is keeping the car from starting usually the red theft deterrent light stays solid when you start the car.  I know in some cars you can turn the key to ignition and leave it sit awhile.Advanced

So, I read somewhere that to reset the computer you pull the ground terminal on the battery and let the car dissipate any charge over 24 hours. So I pulled it last night and am waiting till after work to try again.

Actually, 20 minutes. And it cured a factory immobiliser problem for me on a Lexus LS once.

Well, I'm at work now, and it is a decent walk back home... but I will be testing it tonight, just scared doodieless that I damaged my car computer... and I am through trying to get the remote start to work, wish I would have listened to the echo throughout every forum I read "don't try this yourself, take it to an installer and spend the money" btw, thanks dasbogie and howie II for all of the assistance!
