I have a 2000 cavalier, 2.2 with 150,000 miles. I was driving it and the temp gage was almost to hot, so I pulled over and let the engine cool down. When I pulled over the antifreeze was coming out the overflow. I let it cool down and put more antifreeze in it and drove it to the closest gas station. When I had someone come to look at it now it will not start. It will turn over, just won't actually start. Also, on the way to the gas station, the temp gage kept going from hot to cold, like the car had been turned off.

HELP!

Okay
Here's the color codes:

From Regulator connector IASF

I = Green w/red striped goes to the charge indicator light then to the ignition switch.

A =Yellow white dotted is tied in with the Black orange which is the alternator output wire going to the positive battery post.

S=White and black striped goes to the stator winding at the alternator

F=Orange and light blue is the field winding

Disconnect the regulator connector jump A to F what you're doing is full fielding meaning you are bypassing the regulator and making the alternator throw everything its got. If the voltage increases the regulator is Bad and if it doesn't increase the alty is the problem.

Hope this helps
