checking for power in and out of fuses needs to be done here to make sure your getting power to all thing do with the key in the run position then go from there try not to just throw parts at it it gets frustrating

well i went off a jump and upon landing it quit. everything worked fine pre-jump haha
symptoms:
no gas or voltage gauges (but works when doing the self diagnostic test)
cranks and cranks
i have fuel getting in
no spark
checked all grounds and came back good!
i already replaced the CPS with high hopes :/ but it did nothing.
so i wanna say the cam sensor or distributer cap/rotor? ill take a pic of it apart if you'd want. or maybe the ECM has some kinda shock sensor in it? idk. HELP!!! this is my DD!

just re-checked everything and still nothing still no spark!
my next guesses are:
-ECM gone
-CAM sensor gone
-ignition coil
still no spark! my next guesses are:
