A couple of notes a bit late:
Earlier Chrysler and Renix systems had a cam position sensor that required disassembly of the distributor to replace. Later ones (95 and up for sure) do not, and it is dead easy to replace - take off cap and rotor, pull off sensor, snap sensor on, put rotor and cap back, drive away.
I found with my stepson's 93, and later with my 95, that the cam sensor prevents the computer from going through its initial boot sequence, but the engine can run without it. If you turn on the ignition, disconnect the cam sensor plug, then plug it back in, you will hear a sequence of startup noises, and the engine will start. You must repeat this for every start, and because injection is not timed right, it will not run as well, and may overheat, but it is a good way to diagnose if this is really the problem, and it just might get you home.
When the sensor went bad on the 93, it set only the correct OBD1 code. On the 95, it set both cam and crank sensor codes, I don't know why.
