I would check to see if the spark plugs are fouled. Or you might have a bad ignition control module (mounted under the coil packs). Auto Zone can test the ignition control module.

SOURCE: 2000 Pontiac Bonneville SLE starts

You could have something as simple as a loose vacuum line or you could have a problem with the ( IAC ) Idle Air Control Module. You can CAREFULLY spray carb cleaner along the lengths of vacuum tubing in short ( 1 second ) bursts - if the idle races, then look where you just sprayed for a loose , fallen off or cracked vacuum lines. If that doesn't work then you'll need to have the IAC checked to see if it's working properly - your local shop should be able to quickly check that for proper operation. If the IAC is bad, they are relatively easy to change - with the biggest expense being the part. It is also possible to clean out the IAC which may restore operation by removing the IAC from the intake system and blasting it out real good with carb cleaner, then re - installing the IAC and testing it by starting the vehicle. Hope this helps!

Hi, Very carefully. You'll have to get on top of the engine to remove the back plugs.
Just take your shoes off when you do this so you don't break anything. Also prop the hood up so you can access the plugs better. Good luck.

What's missing ? Does it have spark ? Pull a plug wire off the vehicle an see if it has spark ! Buy a fuel pressure gauge an hook it to the schrader valve on the fuel injector rail . Is there fuel pressure ? Does the engine have compression ? No Start Diagnostic Basics EricTheCarGuy
