Crank but not starting ( no spark!!!)

Okay so i know theres probably a ton of these posts, but all that i have read are not like my case. i bought a 95 integra and it ran for a while (less than an hour) then wouldnt start, after forever of troubleshooting i ended up diagnosing and replacing the ecu and it worked, for about another few hours. Now the car isnt getting spark but i have checked and i see that theres a bad ground on the distributor, specifically that blue wire on the second connector. im not sure where it runs but i just wanna see if anyone knows where it grounds out? thank you (this car has been a pain)
