unless you have the key fob also,you need a new ignition switch,with key fob and key with a chip in it,the switch turns on the fuel pump when the chip is recognized,take it to someone that knows what they are doing,you CANNOT hotwire it.

are you sure that you changed the ASD relay? that code is for no signal from the ASD to the PCM. Check that you have constant 12v at the relay base and that you have switched voltage when the key is on at the relay base, then make sure you have continuity to ground at the relay base. If the relay clicks when the key is turned on then the internal coil is making and should be sending a signal to the PCM when the key is turned on.

yes.
the engine computer does not know when to fire the plugs and injectors.

could be a bad sensor, fuel pressure regulator also recommend checkin fuel pressure for fuel pump and fuel filter

Low fuel pressure or problem with spark plugs or crank sensor is got dirty and needs cleaning or its time to replace crank sensor.

These will help.

Thanks.

sounds like fuel pump or fuse or relay cheack for fuel preasure at injector rails if you have fuel preasure then check to see if you have spark at plugs if not replace crank sensor.

This could be several things the first i would think it to be is the coil but if its not then it could be the distributor ignition pickup or the ignition control module or the crank sensor.My guess would be the coil.

You probably have a bad ignition coil. Which engine is in this truck? 3.7, 4.7, 5.7 or hemi

Check plugs again and see if they are fowled out.. check wires and distributor also
