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?

 

check for 12 volts at the coil harness, each coil should have voltage with the key in the on position and engine off
If no voltage look for an ignition fuse issue under hood fuse box,
If possible get a scanner and look at the theftlock status and make sure its enactive

You could check the VATS system. turn it off and try to start it.

 

Thanks for all the insight. And sorry for the duplicate thread. I’m going to try out a crank sensor. I talked to a hummer tech, he told me the theft lock system disables the fuel so it’s not in the equation here. It would not disable the ignition.
