Hey guys I've got everything squared away besides a few things. I got a new fuel pump and CPS and battery checked everything out hocked the new fuel pump up had to stretch the hose heat it stretch it and hose clamp it to the pump and pressure regular. Injectors barely getting fuel so no fuel to cylinders so no combustion... cleaned the lines cleaned the injectors idk what to to now... any help?

Tell us what bike you have. What is the Fuel pressure?

 

Depending on the year and model it may have a fuel pump relay. If so you can remove it and jump the fuel pump on to always run. Then see if the bike will run. If it does then remove the jumper wire and have the relay tested. Do not leave the jumper wire in place other than for testing!

Are the fuel injectors operating properly? Also, check the pressure. May need a new regulator.

 

heated and stretched the lines does not sound as good as new proper size lines.
test the pump for output pressure. then test for volume. this can be done on the bench using even water or safety solvent.
it could be bad pump, malfunction in the pressure regulator or low voltage.

 

there were some issues with xl pump systems a while back. you need to do a fuel pressure test and see where that is first, then you might have to try to remove the assembly and bench test some of it to get a final diagnosis. fuel pressure test first.
