Default No power with key at ON???

I have been having an issue where I will have power with the key to ACC but the moment I turn the key to ON every thing is dead and the car won't start. sometimes if I wait a little bit with the on ACC then turn it slowly to ON I will have power, but then when I turn it to crank everything loses power. I also have been having the sticky starter issue, I have to turn the key to start a few times or pump the clutch to get the car to crank. I have found the thread on the Evil forum but I am confused, I feel like a few posts have been removed.

Have you checked the power at the switch terminals? If there is no power at the switch (I assume 2nd gen; Should have power to ign1 and ign2 in on position, no power to ign2 in start position). I'd bet on a bad ignition switch if you no haz power there.

I am going to test the switch tonight, it is just odd that not even my e-fan will work after I lose power. It is wired off the fuse box and is contorlled by a toggle switch.

Do as Gunny suggests and check the ignition switch, from description of symptoms that's probably the source. As far as having to pump the clutch to get it to crank, that is most likely a bad clutch switch, you'll want to check that as well.

As far as the e-fan wiring goes, explain to us how it's wired. Are you saying you tap a constant hot +12V at the fusebox, and just manually switch it on with the toggle switch? If so, then there's 2 possibilities as to why it doesn't work:
(1) The constant hot +12V you think you tapped in the fusebox is really a switched +12V source, or (2) Bad ground in the e-fan circuit.

Well A funny side note. I killed the battery because I left my lights on, so I jumped it, It had zero issues, minus the fact the vehicle I tired to use didn't have enough amps to jump my car. the starter cranked the 1st time every time.
