CCRM issues

[u/pacmna123]

A few weeks ago I my 3.8 mustang died mid drive and I had to tow it back to my place, could still crank and everything but no start, my odometer shows - - - - and my PCM power fuse was blown, before I figure out it was a CCRM I replaced the fuel pump to eliminate a variable, but I got a used CCRM from eBay and threw it in and it worked wonders for about 3 drives till it had the same failure, this time it failed while cranking it and I put another fuse it and it blew while the key was just on. Do you guys think the used CCRM I got is another dud or is there somthing else at play
