Moving to the correct section. Welcome to the forum. That's the longest run on sentence. Ever.

 

What color smoke?

Sounds like bad PCM..

 

X2! No buss is a communication failure in the pcm itself.

 

blue and white

 

will a bad pcm make it smoke

 

Blue is oil, white is coolant. (or, just condensation burning off, how much you get makes a difference) Oil is more than likely valve seals.

Losing any coolant? Oil??

 

not losing coolant or oil replaced camshaft sen now hard to start and white smoke until it warms up ( thanks for reply )

 

Check fuel pressure.

The white smoke isn't a good sign......
