Sounds like a computer problem. Check the fuses like Archie said. Does the check engine or service engine soon light come on while cranking? If not, it's definitely a fuse or computer problem. HTH. -Jim

no the check engine light does not come on and checked the fuses all are good. I am not getting 12 volts at the coil shouldnt i get that even if the computer is bad

Under the dash there's probably a fuse. All by itself. That's the ignition fuse. See if you can find it. Since you have power at the coil, what about a bad ground? Have you checked for that? The check engine light should come on with the ignition on and the engine not running. HTH. -Jim
