I have a 88 crx with a b16a recently I had a no crank problem so i replaced the starter. worked fine for a few days then again no crank. it is a reman starter so i guess it could be bad again what else could it be? maybe bad ignition switch? also I dont know if its related but my tach is jumpy past 4k. this all started to happen around the same time.

 

test out the ignition switch
