Well I have a 2000 Jeep grand Cherokee Laredo with a 4.7L V8 power tech engine. The problem is that I'll turn the key and the gages won't move. I'll start it up and it'll run for a few seconds and then immediately die.

What is your question?

I tried giving it gas and it still wouldn't stay running. The alarm doesn't work either. I tried taking out the computer and sanding the grounds out but still nothing. I'm guessing it electrical. Gages won't move, it'll start but won't stay running. Only runs for a good 2-3 seconds. I'm not sure.
