Keep in mind that the distributor itself has sensors in the bottom. If you get a CODE 4-Crank Angle Sensor-you will eventually be unable to start the car until it cools down a good bit and then it will run for a while and die again. Assuming a D16a6 with a TD-02U dizzy you will eventually have to replace the entire thing. (want one I have it for sale somewhere on this board)
I will agree with others-that you must check for codes. Even with a swap there is no guarantee that something internal has failed. The evidence of bearing failure is that the inside of the cap and various components will have a coating of a reddish dust. The other possibility is that you have a wiring problem at the connectors. If you have a PM^ ECU and you have done any arc welding without removing (I have one for sale) it is possible that it is bad-but very unlikely in general. If you have any water in the passenger footwell-clean up completely and check all of the wiring there.

Good luck
