Will turn over, but not start

[Calimaw]

My father and I changed the oil the other day in my girlfriends 07 Aveo moments after she arrived.

After changing the oil the car would no longer start. It does turn over, there is fuel in the rail, and I can hear the fuel pump prime.

I am not sure if perhaps while I was below removing the plug if my father bumped some sensors by the filter when removing it? Would this even cause this sort of problem?

There are no trouble codes reporting on my OBD 2 scanner either.

Checked what fuses could be visibly verified as good and working.

Check the valve cover and make sure there is no oil spilling over on the plugs. Aveos are really bad about leaking around the valve cover.

[Calimaw]

There is some oil in there, didnt clean it really well but tested for spark and there was none.

[Calimaw]

Cleaned the plug boot well and still no spark. I have trouble imagining that all 4 boots lost connection and not at least 1 sparking intermittently. I'd be able to hear that cylinder fire if that were the case.

It just lost all spark 15 minutes after it was just running. Coil pack problems? What else further up the line could cause this?

[xintersecty]

Yes, the coil pack could have gone bad. Was all four holes filled with oil? It could have damaged the coil pack.

[Calimaw]

Yes they were. Tried another coil pack and it made no difference.

As I had indicated before, the valve cover on these things leak. The seal gets hard and then oil leaks past it.

As with a no spark condition, the plugs, the wires, the coil pack and the computer needs to be working.
Did you really clean the oil out of the spark plug holes? I usually try and suck up as much oil as I can, then I remove the plug and clean the plug. The wires could have been damaged by putting them back into the oil filled plugs.

let us know what happen

[Calimaw]

Well here we go, I finally got some codes I'm about to look up; here they are meanwhile

P2101
P2105
P2106
P2110
P0606

[Calimaw]

Rounded up the information on the codes.

P2101 - Throttle Actuator Position Performance
P2105 - Throttle Actuator Control System - Forced Engine Shutdown
P2106 - Throttle Actuator Control System - Forced Limited Power
P2110 - Throttle Actuator Control System - Forced Limited RPM
P0606 - Engine Control Module Internal Performance Error

Looks like 2105 is explaining why it wont start, and that I'll be looking into the TAC.

[Calimaw]

Cleared the codes to try to lift the shutdown but to no avail.

However these 3 codes came back after trying to turn it over again.

P2101 - Throttle Actuator Position Performance
P2106 - Throttle Actuator Control System - Forced Limited Power
P2110 - Throttle Actuator Control System - Forced Limited RPM
