87 Plymouth reliant trouble codes 12 22 24 26 52? Came to the conclusion it is the computer causing all these problems how do I get the computer programed to this car?

I have replaced the coolant temp sensor the throttle position sensor replaced the oxygen sensor all of which three times. I have done the test to see if the wiring is ok which it is. I need to know how I can go about getting a new computer programmed to the car. Do I need to take it to a specialty shop or what tool do I need to use for it.

If you could find a salvage yard car with same year/engine/trans you might just swap ECU. These units seldom fail, but it does happen. First insure ECU is properly mounted and grounded--same for engine.

Why does my 87 reliant stalls when it gets hot.

Yes, the pick-up coil was a common cause of what you describe.
Drive along and suddenly die, but by the time help arrived it would re-start, and run for a while again, then quit again until it cooled down.
