I know the sticky and the ignition switches and grounds but my issue is a little more specific. If I have my knock sensor hooked up the car will act like it loses power to everything while the starter tries to engage, cause all the clicking of relays and the starter but the starter motor does nothing, I've replaced the ignition switch (yesterday) and crankshaft sensor. The car throws no codes and clears it codes. I'm trying to narrow it down but it seems the knock sensor causes all of my issues the connector always has the slightest bit of oil on it. Could it be the knock or something a little deeper causing the issue?
