I have replaced my computer 4 times in 3 months. I have replaced coil, wires, plugs, crankshaft sensor, camshaft sensor. Van originally died at red light. Second computer lasted about a week. Third and fourth computer shorts out after plugging in. I usually get error code p0203 or p0303. Van runs but very badly. Took to dealer he said new computer and run a new wire to fuel injector number 3. I replaced computer and this one shorted out also. What is knocking out the computers?

You or the dealer are going to have to check each pin on the PCM plug-in, there is a short somewhere in the system, that is more than likely grounding a live circuit, or a bent pin that is shorting.

You can try disconnecting all the sensors, plug the PCM in and then plug the sensors in one at a time to isolate the problem, but you will probably fry another PCM.
