P0339 crank No start, wrench light

[Silverslow5.0]

Hey guys I got a problem with this pos lately, so I blew the motor last year. Replaced it with a brand new long block. Installed a GT350 manifold to go with it and ever since I got it back, the car will not start. It will keep cranking and a wrench light comes on. The codes a P0339- crankshaft position sensor circuit intermittent, and a P06E9- unknown sae dtc. The car sat for a year before finally repairing it, the only way I could get it to start would use starting fluid and I wouldn’t experience any drivability issues. The car pulls hard but the no start issue is the problem

Was there any solution found to the problem ? I’m running into the same thing and need help.

What I found out what was wrong. There’s a ground on top of the engine bay, actually on the firewall behind the intake manifold. That was loose and tightened it, another ground is next to the starter. It has to be secured otherwise it won’t get any power to the pcm and throw a p0339 code. Also replaced starter, cars been fine ever since
