Hello Ken,
have you checked the plug holes to make sure your cam covers haven't leaked and buggered your coil packs/spark plugs?

Not yet

Cam covers done about 1 1/2 - 2 years ago

Righto, tbh still worth checking imho - coilpacks are expensive to have it go again

Code 19 is a crank sensor fault code, unless the codes were read with the engine off
first check is to see if the plug wells are full of oil, if so the cam covers have failed due to blocked breathers, or the gaskets were not gen gm, or the wrong sealant was used.

If it is the crank sensor do I need to get from dealer or parts store?

probably dealer, AndyC can get you dealer discount an posted from bury Vx. think there are two different connectors for crank sensors so easier to just get from dealers unless you take the old sensor to such as eurocarparts
