    No crank no start

    I’m having the dreaded no crank no start problem. I’ve kinda narrowed it down to a few things. A faulty clutch switch, bad keys (none work) or a bad Ews. I was able to push start it by letting it roll and popping the clutch. My question is if my Ews or keys are bad would I be able to pop start it still?

    No you shouldn't. Clutch switch sounds likely.

      Is it not starting at all? Or is it not starting on the first crank but fire right up on the second?

        No. Since you were able to push start and run the engine, then key and EWS are good, but if the EWS internal relay is bad then it can't run the starter.

        Pull the EWS off the connector, key turned to START and measure pin2 and it should be 12v. If not then bad ignition switch.

          It’s not starting at all. Dash light up fuel pump primes. But no crank whatsoever.

            Check EWS pin8 for voltage toggling when activate clutch pedal, or use INPA to read the status.
            If everything is good then EWS pin1 should have 12v when key turned to Start
