2001 bonneville sse will not start has new starter, starter bumps but will not turn engine, will not jump start either

the higher the compression ratio the higher the octane rating required
normal compression ratio 10 or 11:1 will run on 91 or 95 octane rating
higher will require 100-110 octane rating or aircraft engine gas
superchargers only increase the amount of air available for combustion
it is the compression ratio that determines the octane rating required

check for a signal at the solenoid it sounds like an issue at the switch their is a starter relay as well as a fuse

What you need to do there is to turn the ignition switch on and off three times, leaving it on the third time. Leave it on for about fifteen or twenty minutes and the light should become steady. then you can start the engine. (I usually put a jumper battery on it to make sure it does not knock down the battery too far) If that fails to work, then the problem likely is in the switch or the security module.

Sounds like your starter motor is bad. Is the starter motor spinning?

Under the back seat. The seat just pops out.

It sounds like you have a short somewhere that is draining the battery...this type of thing is usually caused by a faulty voltage regulator. I recommend taking the alternator to an autoparts store to have it tested...don't be surprised if the alternator tests good; a faulty voltage regulator can and will drain a battery in a matter of hours. I am including a link where you can order a voltage regulator for your Bonneville or, while you are at the autoparts store, you can buy one there. The link will help you to see what the voltage regulator looks like so you can identify it in your engine compartment. Hope this helps, good luck!

its possibly the cylinoid or the ignition try testing the starter, let me know if that works...

Hello, you seem to have a problem with your anti-theft system the ignition lock cylinder has two wires that are very small and are common at breaking because every time the ignition switch turns the are being rocked back and forth, or either there is a malfunction in your key, but odds are you will be replacing the cylinder. You will also have to have a new key made.This fix is kind of exspensive so I would advise you to let the dealer do it. Besides when putting the switch in it could be possible to damage the new one so let them have that headache. Thank You

built into the pcm.....replace the key lock cylinder....get a new key with the same code as your old one and cut it to the gold key you get with the key lock cylinder

P0044 - HO2S Heater Control Circuit High. Put a new O2 sensor in it and you should be good.
