I replaced the under hood fuse / relay board, now it starts, sometimes.

Once started it idles and seems to run fine, have not driven it. Problem, if I run the RPM above 1,500 it throws a code 5200 which seems to be crank position sensor. I already replaced that, could I have a weak new sensor?

I have a no start issue, starter works fine. I would sometimes start and run fine, now never. It had a code for crank position sensor, replaced that. Found the 2 wires at the connector were twisted together and basically connected together. Repaired the wires going to the sensor. Now no start.... Re...
