Changed spark plugs, leads and I tried a new coil pak.
Used multi-meter on cable running into coil pack, constant twelve volts.

Is this a Crankshaft sensor issue? If so where is the the Cps located?
If not why wont my car start? :(

I believe the crank sensor for this vehicle is on the lower left hand side of the engine under the exhaust manifold. Looks like the blue wire on this diagram should be the signal wire back to the ECM and the green wire should be power to the sensor. Check for a pulse on the signal wire while cranking. There is also a cam sensor shown here but go for the crank sensor first.

Thank you for the reply, on the left hand side of the engine their is literally nothing but the exhaust manifold and alternator. I can see anything along the lines of the crankshaft sensor.

Well the crank sensor has to be somewhere it is able to be in contact with crankshaft to pick up a signal, so according to the book it should down there, but if you can dig around a bit in the wiring harness and find these plan green and blue wires together (and they look like they are shielded together to prevent the signal from being interrupted to ground) you should be able to find the sensor. Take a good look at the diagram I sent you, it is going to be a three wire sensor with those colors, the crank position sensor is a main input to the ECM, so you should not have too much trouble locating it. There wont be any other sensors with the same wire coloring. Sometimes as a Tech you have to dig a bit with little information to find a problem. Keep looking you will find it. Sensor wiring blue, green, black/blue. That is your crank sensor. Do not let it beat you.
