there are several things that can cause that , low oil level and bad quality oil , in other words ,needs to be changed, if oil gets thin enough can ause your concern , bad glow plug relay , fuel draining down overnight , or even oil draiing from hpop reservoir overnight , the two i mentioned first being the most common

Just changed the oil yesterday and the fuel filter. I have a programmer (superchips) it threw a p0603 code but i cant find the code book if anyone has one handy let me know the code thanks.

p0603 is a keep alive memory code that is set anytime you use that programmer or change settings in the pcm with the programmer, if that is the only code you have , need to test glow plug relay if oil is good,you still could have oil draining out of reservoir overnight , but start with the basics
