2006 mercury 60hp 4 stroke intermittent no start

[nathanjfla]

I have a 2006 mercury 60 hp 4 stroke that has an intermittent no start. Sometimes it will start and run fine. Sometimes it will start then shut off. Sometimes it won't start at all. When it doesn't start at all, it has no spark. I've bypassed my kill switch. I've replaced the pickup coil. This motor is killing me because Every time i try to diagnose it, it starts and runs fine. Can someone give me some insight?

Also my battery is new and I've tried multiple batteries.

can you hear elec fuel pump turn on when you turn the key,i would remove and clean connections on top of pump also remove bottom relay and swap with trim relay clean all connections see if that helps also battery cables might have a fault ,the only way to dignose problem is when it wont start,good luck let us know what you find.
