Default Need help with ignition timming!!!

I need help with getting my engine started. My coil pack does not get any spark, I changed my cam gear sensor and it still doesn't start. I was wondering if it could be my ignitor. By the way I also changed my coil and got the same thing trying to turn it over. Any help will be appritiated, thanks.

how did you test that your coilpack isnt getting spark? the coil pack shouldn't "get" spark, it should "give" spark. did you probe it for power in? did you check the wires for arc when cranking by unplugging one and laying it on a metal part of the engine and seeing if it sparks when cranking? I dont have a coil pack setup, so maybe im way off.

I checked the spark coming off the coil by taking off the plug wires and put my finger near it and had someone turn it over and no spark.

hmm, i dont think that is a very good test... id keep the plug wires on it, and hold the plug end near the engine block somewhere (only a millimeter away, the spark upon starting isnt the strongest and wont arc over much distance) and if no spark there, try another wire.. if you get no spark on one wire it could be a bad wire. Your body isnt a good ground for the spark and its frankly foolish to hold your finger near because it will give you a couple thousand volts to the fingertip. If you still get no spark, check the power in wire for the coilpack and make sure its getting 12v, or whatever its supposed to get during start/run on the ign switch. If no power there just keep chasing it until you find power. its all power and ground, super simple circuitry.

A little background, ie, recent mods/work done? Did you check the crank angle sensor as well as cam angle sensor?
As RaceFace said, test using leads grounding on the block. If nothing on any lead, get out the multimetre and check the plug going into the coilpack.
Failing that, trace the wiring back to the ecu, and test for an outgoing signal to the coilpack.
Has the ECU thrown any fault codes? You should get it scanned before you go to far with your troubleshooting

I know that the crank angle sensor works because it still gets fuel. I don't have a multimeter but will a voltmeter work?

yeah voltmeter will work fine, a multimeter is a voltmeter that has other functions but the only thing you need to see is if you are getting voltage and if so, how much. better find out what the correct voltage into the coilpack should be so you dont think its ok if it gets the incorrect voltage. If you are not firmiliar with using a voltmeter its easy, just make sure you ground one of the leads coming from the voltmeter and probe the coilpack power-in wire with the other. The crank angle sensor controls injector timing? i am asking as i have no idea. good luck, let us know what you find.

CAS monitors engine speed and piston position, and sends signals to the ECU to control fuel injection, ignition timing and other functions

i see. that makes perfect sense, just never thought about it enough. What does the cam sensor data allow the ECU to change? ALVS timing on the 06/07's?
