First point is to find the sensors, pictures would help but I've only got boost one and its on here in another thread. Here's a picture of engine with roughly where sensors are.
1 Temp Sensor.
2 Crank Position.
9 Camshaft.
13 Air Temp/Boost.
15 Fuel Pressure.
Every case where Crank and Cam sensors are mentioned there is always a wiring check because the signal has to be right. Think tfb refers to it as a square wave with no fluctuations and mentions it needs Oscilloscope test.
Got a picture from a scope page somewhere.

 

Thank you so much for all your help. I will give this a try tomorrow

 

Here's a scope picture for a cam sensor.
