07 Pontic G5 Does not start properly. Engine turns over and over but does not fire up on 1st try. Engine light is on, scanned error was Camshaft position sensor. Creared code, Came back. Tried new sensor, Cleared but came back. Also changed spark plugs as was time and was at the store. Feels like a timing issue (belt?) but i guess could be computer related as engine runs with dependancies on sersors. Either way am askin for help/ideas.

SOURCE: jumped timing?

It really does sound like the timing went out of whack. The timing belt should be replaced periodically, according to your owner's manual. It may have worn and stretched just enough to slip over a cog a bit. Remove the timing belt covers and check the alignment of your cam and crank. There should be subtle marks on the cogs and the rear cover or casting. The compression will be good during a cranking test, but will not be ok during a running compression check. Replace the timing belt and check the pulleys. If your timing belt did not slip, the timing chain tensioner or guide shoes may be worn and will require replacement.

The paperclip test wont work on the OBD2.. tried it many times. i've read at other places that they're replaced all the sensors, fuel filter and even took them to the pontiac dealers. the dealers say there's nothing wrong with them. i've been having this problem for about 2 months now.  still can't find the answer

Check the cap and rotor - if the contact point for cylinder number 5 is worn or corroded, or the edge of the rotor is smooth, you need to change them (the rotor's edge should look like the edge of a quarter, with ridges). If the contact point on the cap is worn out, it won't fire the plug.

There's a chance that the fuel injector for that cylinder isn't firing, so that would be something to look at if the electrical work doesn't fix the problem, but it sounds as if it's more of a problem with the electrical parts than a fuel injector.

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

SOURCE: replacing bad camshaft position sensor

1. Disconnect battery ground cable.
2. Remove water pump pulley attaching bolts, then the serpentine belt and water pump pulley.
3. Disconnect sensor wiring connector and remove sensor retaining bolt.
4. Twist and pull sensor to remove.

Reverse procedure to install and prior to installing new sensor, lubricate sensor O-ring.

It is located under the water pump. Make sure when you remove the sensor that you rotate the crank shaft and look in the hole to make sure the pick up magnet is still in there. Sometimes they come loose and cause a no start or long crank. You will need to have the code cleared still.
