my 2008 saturn aura wont start. has 12.5v from the battery and a new starter. has codes p1682, p0685, p0223,p0122,p0118,p0107. took it to two shops in my town, and both shops could not find the issue.
Does it even crank over?

F a crank no start, first you check for spark. Then you check for fuel. Depending which one is missing, go from there. Another thing to possibly rule out a timing problem is to open up the oil cap to see if you can see the valves moving when it is cranked. If they don’t move you know you have an internal timing problem. If they do move you can still have a timing problem but less likely.
Two shops looked at it and couldn’t tell if it is spark, fuel, or compression? Amazing.
no. the starter doesn’t even want to engage. but engine is not locked. turned it over.
the car has spark and fuel according to the last shop i took it to and engine turns over when they put a ratchet and 18mm to the crank. I never had any lights on the dash until it did this issue.
Possibly a Pass-Key security system problem with the key. Is the security light located in the tachometer illuminated? Do you have other keys that might work?

Test for the Pass-Key system 1st as Nevada said above, then if the starter does not engage then you have to make sure it has battery volts to the starter (big wire) all the time and the while trying to start the vehicle the signal wire (small wire) should have battery voltage as well, but only while trying to start it… If no power to the signal wire then you check to see if you can get it to start while moving the shifter back and forth a little in park and neutral…
Check for a bad ignition switch, check ALL fuses, check for a bad neutral safety switch, check to make sure the starter relay is clicking/working, also looks like you have the BCM and the ECM involved with making it start …
Also check to make sure the shifter cable is still attached to the transmission and the shifter…

Try shifting the transmission into neutral and then see if the engine starts.

Shop turned motor. Shop says starter is/not getting signal to crank when key is turned? Good place to start diagnosis at least.
According to OP the shop stated spark and fuel are good but engine does not crank. How would you determine spark and fuel on a no-crank? Sounds like a good place to start diagnosis is at a better shop.
Among the many fault codes listed are 2 for the throttle position sensors. At some point GM disabled engine starting when certain electronic throttle codes are set. They don’t want a runaway engine. Simple examination of data with a scan tool will point in the right direction.

A faulty ignition switch can easily cause a fails-to -crank. And the first code you list is for the ignition switch. Suggest to start there & follow DMP’s suggestion above; i.e. test that the starter motor is getting the proper voltages w/key in “start”.
@asemaster makes a good point above, how can the shop you are using say the spark is good when the engine won’t crank? On most vehicles, for safety reasons among others, the engine must be cranking before sparks are allowed. Suggest to ask them to explain this unuexpected claim.

I ended up replacing the ignition switch myself. because the story at the last shop did not add up. The car now starts. thank you.

The exact cause for that sort of symptom may not always be easy to find, but the reason why it isn’t cranking should be pretty obvious provided the shop tests the voltages at the starter motor. Which apparently neither did. That’s a shame (provided you offered to pay them to find the cause). On the + side, you’ve discovered two shops to avoid in the future. Finding a good shop seems like your first priority. Suggest to make this a project so you’ll be ready next time you need a shop. Ask your friends, co-workers, anybody you know which shop they use. Interview of few of those shop and decide which has the maintenance & repair philosophy you most agree with. Ask the shop you choose if an annual shop “general inspection” might be a good idea. They can look for signs of developing problems and give you a heads up. Best of luck.
There is no power to the starter solenoid, if there was, the engine would crank.
Starter motor operation is controlled by the PCM, this type of repair is too complicated for a typical auto maintenance shop.
My Corolla wouldn’t crank one time, & it had had power to the starter solenoid. If the shop measured the starter motor voltages and they were correct, I’d expect them to say so. Rather than “we don’t know why it won’t crank”.
If you want all your questions answered, speak to the mechanic yourself.
I had that intermittent one time. Ordered a new switch but when I went to put it in found out it was just out of adjustment. Turning the key didn’t move the slider on the switch enough to activate the starter. Returned the switch.
Your Pontiac uses the same ignition switch as this Saturn. Some believe too many keys will harm the switch, I have never replaced a switch that was worn out by too many keys.
No this was on one of my rivieras with the switch mounted along the steering column, down below.
Found internal fuse block losing ground to starter, replace fuse box problems solved. Check your grounds, that’s why after getting hot. Cool down and guess what good ground again and starting. Hope this helps
