The car was working fine, I shut it off then it wouldn't start again. It gave me a code for crankshaft sensor, so I replaced that. Then I changed coil pack. I am still not getting any spark, but car cranks like it wants to start it just wont catch.

Hi,

We need to find out if there are still codes in the system. When you replaced the CKP sensor did that code go away? What was the actual code for the crank sensor?

Clearly the CKP sensor will cause you to not have spark so we need to chase that down. If the code is still there then it wasn't the sensor itself. It was more than likely the wiring or even the ECM.

Let me know this information and we can go from there. Thanks

The crankshaft code is gone. The car isn't spitting out any codes anymore. I am not quite sure if my firing order is correct, but I am pretty positive it is. But maybe you can reasure me it is: 123456. That is what I believe it is

Yes. Firing order is correct but what was the actual code that you were getting for the CKP? Was it P0335? If so, where did you get the sensor from? I attached some info from other technicians that report aftermarket sensors did not correct the condition. Then when they replaced it with one from the manufacture it fixed it.

Then how did you check for spark? I just don't want to tell you to do something you have already done. Thanks
