WHY DOES MY IGNITION FUSE KEEP BLOWING

It started as a fuel filter problem. After getting fuel flowing, every time I turn the ignition, the starter turns engines and then the 40amp ignition fuse blows. Any idea why?

Do you
have the same problem?

SO YOU ARE TURNING THE IGNITION TO START OR JUST THE ON POSITION?

SOUNDS LIKE A BAD GROUND. CHECK ALL YOUR LARGE GROUNDS LIKE THE ONE FROM THE BATTERY TO THE ENGINE IS WHERE I WOULD START.

I've checked all grounds, replaced relays, checked fuses, and now replaced starter with selenoid and when I try and hook up my negative battery cable, the starter true to start engine with the ignition off.
