I have a code 1351 that only shows up after running vehicle to operating temperature-let it set for 1 hour and then it will not start on first hit of ignition key. On second hit of key, it starts right up. Or if you let it set and cool all night it will start right up. I have replaced distributor cap, rotor, i.C.M. Module, coil, crankshaft sensor, camshaft sensor, plugs and wires. I have also replaced the e.C.M with a remanufactured one flashed from auto zone! What else could it be? Thank you.

I believe the problem you're having is ignition, not where the key go in, but what the key activates in the steering column, also you may want to check the "VCM" which provides control of the engine systems (vehicle control module) or the "PCM" (powertrain control module) check into that and get back to me.
