]After not getting spark at my coil and doing multiple testing. I found both the crank and can sensor bad. The magnet on the pickup broke off. And when looking at live data while cranking I had 0 rpms. After changing them the jeep, 97 country, fired right up and ran a little rough. After about one minute it cut off and will not start again. My crank sensor if from advance 87$. I do still have rpms at the scan tool which tells me it didn't fail but all symptoms point that aftermarket sensor failing right off the bat. Code I have now is 1389 no ASD output. All fuses and relays are good.
