Percolation? Heat soak? Don't drive during summer??

It doesn't do that constantly, only when I turn the key to the on position before I start cranking it over. Once I start cranking the engine over the coil is normal and will only do that again if i turn the key all the way off and then back to the start position before cranking it again. Its weird, I always thought I had an electric pump until Tony found the coil doing that...

Then by all means, ignore all of us and leave it on there. What WERE we thinking trying to help?
