Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
As I am sure you know, in order for the engine to start and run you need good spark, injector pulse and proper fuel pressure (55 to 62 PSI). When it will not start check each one of these and let me know which on is lacking and post back with the results and I will help you from there.

Hi, found new crank sensor to be faulty causing no start at all-reinstalled old sensor & car starts and runs normally when cold, but problem with hot starting still remains.

Brian, so when it does not start are you loosing injector pulse or spark and ot both, are you 100% sure your still not dealing with a bad CKP and or the circuit to it?
