No injector pulse, too low compression, valve timing incorrect, bad ECM or wiring. Assuming that everything you have already installed is in operational order.

It was throwing a code for misfire and burning too rich I pulled the plenum manifold off and had fuel in the manifold so thats why I replaced the fuel lines injector and everythin under the plenum

Double check your work, it is really easy to leave off a ground or sensor wire.

It was running before I changed the fuel lines and evrything but now all it does is crank is there somethin I may be missing can any of the sensors cause it to just crank?
