So we bought a running driving 13 xl ecoboost, when we went to pick it up it started and died and then never started again and it was the timing chain, so we installed a new chain and guides as well as new MSD coils while we were at it. Well no it wont start and that's the only code we get! We hooked up a computer to it and while turning over it shows...
cam and crank syc? YES
Engine start? YES
RPM? 150-160

We are at a loss here...

Kinda surprised you haven't gotten a response. I assure you that there's knowledge here.

It could just be timing chain weariness? Not your fault, of course. But there's just so much already discussed for so long, concerning the subject

Have you done the crank re-learn procedure at the end of the repair section?

P0320 - Ignition/Distributor Engine Speed Input Circuit


Description:
This DTC sets when several erratic profile ignition pickup (PIP) pulses have occurred in the crankshaft position (CKP) sensor signal within a calibrated time period when the camshaft speed exceeds the equivalent speed of engine idle.​
Possible Causes:
  • CKP+ circuit intermittent open (VR type)
  • CKP- circuit intermittent open (VR type)
  • CKP circuit intermittent open (Hall effect)
  • VREF circuit intermittent open (Hall effect)
  • SIGRTN circuit intermittent open (Hall effect)
  • CKP+ circuit intermittent short to voltage (VR type)
  • CKP- circuit intermittent short to voltage (VR type)
  • CKP circuit intermittent short to voltage (Hall effect)
  • VREF circuit intermittent short to voltage (Hall effect)
  • SIGRTN circuit intermittent short to voltage (Hall effect)
  • CKP+ circuit intermittent short to ground (VR type)
  • CKP- circuit intermittent short to ground (VR type)
  • CKP circuit intermittent short to ground (Hall effect)
  • VREF circuit intermittent short to ground (Hall effect)
  • SIGRTN circuit intermittent short to ground (Hall effect)
  • CKP sensor incorrectly installed
  • Damaged CKP sensor
  • Incorrect, damaged or corroded connections
  • Arcing secondary ignition components (coil, wires and plugs)
  • Arcing relays or other high current devices (cooling fan or starter motor)
  • On board 2 way radio transceiver
  • Radio frequency interference or electromagnetic interference from an external source
  • Improperly grounded high power aftermarket equipment
Diagnostic Aids:
The DTC indicates two successive erratic PIP pulses occurred.​
