Dodge Caravan SXT: 2009 Caravan SXT 4.0l will not start. Replaced

Customer Question

2009 Caravan SXT 4.0l will not start. Replaced both cam and crank sensors full tune up even dealer cannot diagnose. No codes. It did start once but ran really rough and smoking.
Odd thing is when on a scan tool the RPM's when cranking got up and then drop to 0 and then up and drop to 0. Really stumped.
Even gone as far as rewiring the 2 sensors to the Computer to rule out bad wiring.

I take it there is no spark when cranking?
Are there any codes in the computer?
Have you checked engine compression?
