Check the OVP as mentioned. The fuel pump relay is adjacent. Clean out any leaves and debris, make sure the relays plug back in tightly

Often cold solder joints in the FPR can cause issues. (You can either replace it or take it apart and go over each solder joint with a hot iron to reflow the solder, btdt)

Did you replace the wire from the coil to the distributor? Old wire might be worn and grounding out.
