#162 of 203 97 Pontiac Bonneville won't start
Jun 06, 2011 (7:57 am)
I have a 1997 Bonneville - was running fine. Went to bank, came out and it would not start. The dash lights come on, but nothing when the key is turned. You can jump it from the starter, and will run 2-3 seconds and just die. Suggestions??

There's a 2nd positive wire that runs from the battery + side to the center of the cowl area. Generally, you can move that connector around (at the battery) to get it running. I eventually replaced that cable (approx $45 at GM) and all starting issues went away.

I had a Pontiac do that years ago = fuel pump was failing
Although your problem does sound more electrical

Your car is 2000 and newer...
Check the ground on rear floor. Remove and clean then retighten.
Check the connections on fuses in the holders under the rear seats. i recall some have found loose connections there--might do that with the ground wire removed...
Check same on the fuse holder in the front... Doesn't the power wire go there and then to the starter?
Could just be defective battery-post cracked. Bridged inside.... How old is battery?

Check for tightness on the back floor fuse set on the clips that the fuses go into. I don't know if you unbolt the box and lift it to get to understide or how. I recall someone men tioned that as source of their problem in Bonneville long back.
The gauges and things going crazy sounds like a drop in voltage symptoms some people have when the battery gets old or bad. But you have replaced battery. Check the end of the positive cable to be sure battery acid didn't seep into it from the battery post and corrode something.

I would check the 2nd positive cable going from the battery to the top of the firewall. I had intermittent issues until I replaced that cable. Since then, no issues at all, except finding a brake caliper mounting bracket to convert from drum to disc on the rear of my SSEi.

Is that on a 2000+ model that has that cable? I know the 92-99 models had one going to the Relay Center for fuses and relay power!
The main cable on 2000 and up goes to the front fuse relay center by the AC accumulator--right fender near front. I need to look into how the power goes from there to starter and others.
