Turn key ON and check for 12V on the main power relay purple wire. If power is there check for 12V on the pink/white wire on the coil and fuel injectors

Kill switch or in gear ? Sorry to ask. Both of these will do what you are having

Thanks for the replies and sorry for the delay in responding. UPDATE. the purple wire has power as well as the coil, there isn't a kill switch just the ignition and it wasn't in gear but I know that's a common mistake. We think we found the problem, a bad wiring harness on the motor, its a $1300 hit but there isn't much of a choice at this point I'll update once its installed.

Just returned from repair shop and they finally figured out what the problem was. A bad alternator. can you believe it?? I sure couldn't ,I never herd of a bad alternator not allowing the engine to at least crank, this is one for the books for me. anyway thanks for the input and I hope this helps someone in the future.
