How to test the main relay?
I've been having trouble diagnosing the troubles I've been experiencing so now I'm checking my main relay. Is there any kind of test with just a test light or battery power that I can do (I have no ohmmeter) to see if the relay works?

I would try putting 12 volts to the trigger wires and listen for a click. If it doesn't click you know it's bad, if it does click it is still suspect and you need to find an ohm meter.
Not w/out the Helm's or if it has a picture on it it might have two terminals with a squiggly line connecting them, that represents the trigger coil. Sometimes they have the diagram etched on them somewhere.
I figured out how to test it and the relay is good. but the fuel pump fuse isn't sending power to the relay. I wired in a fused jumper wire and it turned the fuel pump and AFC on, but it still won't start. I'm not getting spark. I still have no dash lights and I don't know how to test if the ecu is powering up.
