My 7.3 will wont start on the first try its turning the motor fast it just dont start on first try it takes at least two sometimes three trys this has just started recently. any ideas? injector? hpop?
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
