You haven't provided any details about your MegaSquirt ECU; I have no idea what's in it.
It sounds like you're in a little over your head. You might consider taking your project to a professional and have them complete it.

its megasquirt v2.2 and i bought the car with it already wired in. i have done alot of research and i dont see how removing the relay/power board would help.

If the relay board is causing your problems, removing it will help. It's generally not needed, and it just adds another layer of unecessary complexity.
If you want to keep it, then you're going to have to listen to my suggestions. Take the circuit board out of the enclosure and inspect the board for cold solder joints, cracked solder joints and shorts. If you can't find any faults, remove the relay that's getting hot and replace it.
If you don't know how to do any of this, you really need to let a professional handle this aspect of your project.

im sorry i didnt mention earlier, but i have done that. All the solder joints look fine and i dont see any shorts.
Like i said i would love to just take the relay board out of the equation, but i dont know how. Im sure i physically could, but i have no idea what to take off, what to re-route, etc.

Well, something's definitely wired incorrectly. I'd take a look at the FSM and the wiring diagram supplied by whoever built the MegaSquirt ECU. Those two documents should also provide enough information for you to remove the relay board. I don't know if this wiring diagram will apply to you, but here's the FSM and one possible wiring diagram:
