I had the computer read and it gave me a PO335 Crankshaft Position Sensor A circuit malfunction, PO341 Camshaft Position Sensor A Circuit Range and Performance B1, and Evaperative Emission system Incorrect purge flow. I was told that the place to start was with the Crankshaft position sensor, but I don't know where it is. I was told that its easy to replace but I am having a hard time finding anything on where it is or how to replace it. I need to get my car back on the road so any help would be great, thank you

I think that I found the Crankshaft Position Sensor but I have no idea on how to get to it, let alone get it out. How do I get it out and replace it?

I replaced the sensor, I have also replaced the ignition control module, ignition coils, wires and plugs and it is still does not always want to start. I have not started the car in 4 days I went out and it started pretty quick. At other times it will not start at all and when I check it has no spark. I have checked and rechecked the connections and the wires and they are tight. I am at a loss. Any ideas would be helpful.
