Crank no start, except when starter fluid is applied
 

Hello all! I have a 2002 Honda Civic EX that has a crank no start issue. People have recommended I replace the main relay (2002 model has different relays than previous generations that cannot be soldered), but that did not fix the problem. Just today we found that if starter fluid is sprayed in it, and if it is floored while cranking it, it starts every time. Does this have to do with a fuel sensor? Would it have anything to do with the ignition? There isn't an engine light, so we cannot check a code. Also, it isn't a key immobilizer issue either. Thanks for the help!
