Hello and welcome to Just, Super mechanic here. About your vehicle.

Sounds like a bad crankshaft position sensor, but here is the test for it with the diagnostic aids.




DTC P0336 can be caused by secondary components leaking high voltage into the Ignition Control (IC) module. Inspect for the following conditions:

  • Incorrect harness routing near secondary ignition components.
  • Ignition coil arcing to wiring harness or IC module-Check ignition coils for:
  • Cracks
  • Carbon tracking
  • Other signs of damage
  • Secondary ignition wires arcing to wiring harness.

In step #3 you will need a scan tool. That crankshaft position sensor is in the front of the engine, behind the balancer. 24X

also this morning when i started it sounded like a miss fire even when i went on reverse it died.

That could be related, or it could be a fuel pressure low problem. Normally you would want to repair any obvious, (trouble code) things before trying to diagnoses any running concerns.
