No spark and no fault codes
 

I’ve done all the standard tests and resets but to no avail. Oddly passlock light is acting as it should, there is no error code yet I have no spark.
i am going to switch out the ign switch module. As the starter has been hanging up and I think it’s in the switch. Any ideas?

Possible crank sensor has checked out... Usually these act up a bit before totally crapping out though.

Thanks for all the insight. And sorry for the duplicate thread. Yes I’m going to try out a crank sensor. And it was acting up too. I talked to a hummer tech he told me the theft lock system disables the fuel so it’s not in the equation here.
