#1426 of 2268 2000 Pontiac Bonneville Trunk Leak
Mar 07, 2005 (7:56 pm)
Spoiler is held with 6 bolts fastened through deck lid and foam-type adhesive. Waterproofing material around bolts degrades with time, allowing water to enter deck lid. Water stays in deck lid and then comes out into the trunk when trunk lid is raised. Some potential solutions are to remove spoiler and reseal around bolt holes and refasten spoiler and/or drill hole in lowest portion of deck lid to allow water to exit. If drilling a new hole, good idea to put some paint on so doesn't rust.
#1427 of 2268 2000 Bonneville cranks but doesn't start
Mar 08, 2005 (6:04 pm)
Occasionally, my Bonneville will crank, but it will not start. The service engine light is not on when this happens, and the only way it will start is if I put the accelerator all of the way to the floor. The fuel pressure regulator has been changed. One more thing that has happened this past week is that the security light is on all of the time. Any suggestions?

Is the security system light on. The car won't crank if the key doesn't turn on the security system.

Yours doesn't have a resistor in the key that's a security item?
IF you connect the correct battery cable directly to the starter terminal, does the thing crank? IF you're not sure which does what there, have someone who's done this before jump the solenoid connection that normally gets power from the key switch.
You might have a corroded out cable to the starter from the battery. Try paralleling a jumper cable from red battery post to red terminal on the starter.

I have the same problem on my 99 Bonneville. Last summer, all of a sudden, the courtesy lights stayed on after the door was closed. No intermittent problem here. I had to pull the courtesy lamp fuse and rig an on-off switch under the dash.
But, I am told the problem is in the door latch switch, but I would like to have someone verify the name...is it door lock relay, or door lock switch or door relay, etc?
Finally, how can I fix this myself? I assume I have to remove the driver's side door panel to get at the switch or relay, but how do I do this and is there a good instruction book with photos or is there something online for free?

#1434 of 2268 process of elimination

If the car was cranking, and you replaced an ignition module and a coil pack(s), and now it won't crank, it's time to put one of them back and see if you can't get it going. I'd start by putting back the old ignition module. Are the new parts GM? This is one area where the stock part is generally better than any aftermarket stuff you can buy.
#1435 of 2268 alarm system
