Is your battery good? And just because you changed the alt. doesn't mena the new one is good. It has happened before. If you have a volt meter then test it yourself, if you don't then it is like $10-20 at sears for a digital one, and will save you some headache.

if your alt is good and batt is good you could have a internal pcm problem. check for codes?

yah same crap here, Its the alternator wires go to near where the battery is take it out and the battery tray, follow the wires from the alternator and check the color of the wire at the fuse link near the driverside where the positive batterey cable connects to the car follow the wires down that are atached to the alternator wires,there should b 2 wires that need to be replaced happend to me...
