So I installed a spe cp4 disaster kit followed everything on the instructions primed the fuel system looking for leaks found none. So I put everything back together went to start the truck and it just cranked it was throwing a p2291 code injector control pressure to low-engine cranking so I took it all back apart checked everything made sure connections are good still just cranked then I decided to put it all back to stock and finished that still just cranked so I replaced the pressure control on the top of the cp4 thinking I might have messed it up but nothing still just cranks. I might have gotten like a spec or 2 of dirt in it but that wouldn't stop it immediately from starting right? I should have something I'm all put of options no idea what to do now

 

Any luck figuring out the issue? Currently having the same problem!
