no start

Hi I have a  2008 wr250r and it wont start. I have spark but no injection pulse. all fuses are good and there is power at the pcm. what next?? can any body help??

Possible that the fuel pump has gone out.  It is a known issue with some of the early WR250s.

Do you hear the fuel pump prime when you turn on the ignition?

Yes, the fuel pump runs, and I have spark. Does the crank sensor control spark? What does the lean sensor control? Where are thies sensors located? Thank you for your help. I just need to get my bike going again. I need a wireing diagram that I can see and able to read, the one I have came from yahama and its hard to make out.
