Have you made sure the Battery is fully charged and was the Battery replaced with a new one?

[Brandy0712]

Yes new Battery as old one was on its last legs. Tried 2 new crankshaft sensors same fault. They were blueprint sensors.

Hi, have you cleared the fault from your OBD ?? If you have then it seems to be a wiring fault. Check the sensor connection plug first off.

....And is the Battery 'fully' charged, as they don't always come 'fully' charged but with just enough power to get you started a few times over?

Yes Battery new and full been on car 2 weeks now and it does about 100 miles per day. Car starts and runs perfect just same to codes p0337 p0338

Then that rules that out! 

Do you know anyone with a similar car to yours which you could temporarily swap the crankshaft sensor with thus eliminating the sensor entirely? But in the mean time you could try what Bomber209 recommends, that been the connector and wiring to the sensor.
