We had a similar problem recently at work with an impala. Ended up being some rust build up where the crank sensor mounts holding it away from the reluctor wheel just far enough to not read. So check that real well, maybe try to get a look at it with a mirror to make sure it's seated all the way.
Also with as much testing that you've done make sure none of the terminals in the connector are stretched causing a poor connection.
Something to check...I could see that being an issue too...thanks for the input
Im so jealous. This is one bad arse rig
It looks really bad arse sitting outside my house not running right now

One of these days it will run and be doing burnouts
