Have you checked spark and fuel when the engine does not start?
Are you looking for some possible causes?
Would you be willing to speak on the phone?
Sounds good no problem.
You will need to see if the engine is missing spark or fuel when this no start condition occurs. Is this issue ignition or fuel related? That's what we need to determine. If the engine does not have fuel, maybe we have a fuel pump or fuel pump circuit issue. If the engine does not have spark, then we could have an ignition system failure (crankshaft position sensor)
If the engine is hard starting (cranking longer than normal to start), then either the engine is missing spark or the engine is missing fuel preventing it from starting. The only other possible cause would be an air/fuel ratio condition.. which could be caused by a faulty engine coolant temp sensor or another sensor.
If you did not check fuel pressure and spark when this occurs then that will be your next step.
If there is a fuel pressure test port, yes you can.
I am glad I can help!
