When I start my engine cold it runs great but when it gets hot it looses all spark. I can let it sit over night and it does the same thing? 1995 Mercury 225......I have ohmed the electronics out and they seem to check out fine. I also switched out the ecm with my other engine and made no...
I was running about half throttle and the motor died like you turned off the key. I am getting fire on the top two cyl but not the bottom four? Any sugestions would be great .....Thanks Jeff
