have you checked the ground on the coil connector ?

this is sent from the pcm , if you changed the coil and module & crank sensor , that tells me power or ground or both are missing ?

can you check and let me know ?

the truck still spins over , just want start ,you have no fire , but you have fuel pressure correct ?

is there a red security light flashing or steady on when attempting to start on the dash ?

Please let me know

Thank You
