No spark...crank sensor?? Not getting any spark at any cylinder. Checked all fuses/relays, actually replaced the Ignition relay. Still no spark. Ran the trouble codes, nothing out of the ordinary (cam swap, removed emissions stuff so there are several codes thrown). I have been told by several people that the crank sensor would cause the no start condition. Is there a way to test it? Whether it returns a signal/resistance/some other method? I just don't want to spend 60$ on a hunch. Any help is greatly appreciated. Thanks!

I you have HP tuners in the VCM scanner, under vcm controls, click the special box on the right side, at the bottom there is a button CASE Learn.
Did you install the CAM dot to dot?
usually a cam swap wont take out a crank sensor.

Don't have any tuning software, car has been on the stock tune for nearly three months with absolutely no problems. Yes it was installed dot to dot. Car has randomly started and run a few times since it has been down, maybe four times in thirty or so tries, but has not for several weeks now. Thought maybe a short somewhere but all the wiring I can see has perfect insulation and is not contacting anything that would ground it. Can the crank sensor start to go bad, giving random starts, then finally totally take a ****?

Well of course they can, but what I asked was can they work and sometimes not work? Like start to lose their functioning capabilities, then completely stop working one day? Or do they just die. Because it randomly started several times, but hasn't for quite a while.

Easiest way to check a CKP sensor is to watch counts on a scan tool, also I'd check the wires running to it they run right by the headers. You'd be best to watch live data on a scan tool, or just throw a sensor at it.
