Unless you took off or moved you wire harness
All wires should be in the same spot. It is possible that you pinched a wire. But not likely. Lets see? Unplug wire, see if it fires, if not remove the cover. LOL its a whole lot easier to unplug a wire LOL. And normally the bushing wears and causes the seal to leak. But it is possible to replace seal and not bushing. Just keep a close look for an oil leak. Remove metal shrouds and look at cooling finns to see if they are clogged.
