1990 Plymouth Voyager 6 cyl Front Wheel Drive Automatic

my problem is this, the car running cold was fine. After it warmed up, it developed a rough idle. Then the catalytic converter would turn cherry red. We changed that twice. Tune up, every scensor you can think of. Fuel injecters, computers you name it we done it. Car does not run at all.


please help

. Car does not run at all: could be the Cat is fully choked up the engine is not breathing.

Does it crank and won't start or just won't crank at all/nothing.

I will test the coolant temperature sensor and check fuel pressure to rule out the fuel pressure regulator and pump, clogged return line sounds like its on the rich side.
