Default 408 crank sensor problem HELP!!!

New motor with a 6.0 n 4'' stroke Eagle crank(24x). Car starts & runs but keep getting crank position not verified code. The idle air controller keeps closing all the way once car starts up, so it dies after running for a while. Tried another crank sensor same problem. At start timing is 23 degree, timing stays the same while idle but fuel goes crazy. All verified through H.P. Tuner software. Any help would be appreciated

My 408 did the same thing after the first fire up. I just replaced it and moved on.

Check to make sure the wires are not burned or damaged from the headers.

I hate to be the bearer of bad news but do you think there might be a possibility the reluctor wheel was installed backwards?

Thanks to all for the help guys. I don't think Eagle would have place the reluctor wheel on backwards. Least I hope not, fingers crossed with that been said. Will run a crank relearn tomorrow evening to see if that helps, if not all good info is greatly appreciated.

If you were willing to wait I could fix this issue.
There is no one in the DFW area with more experience tuning SpeedDensity.
