Thank you for your response. You are Awesome!!! I really appreciate that! Did CMP and CRK checks that early saturday morning. Want to tell you what I left out in my initial search. DTC's 135, 155, 161, 302, 141 and 1510 came up while searching DTC'S... Just in case they could be a culprit of my problem... I cleared all DTC'S and ran engine for a few minutes and received PO133, PO155 and PO302... which I know exactly what they represent as you do. So I replaced both bank1 and bank 2 upstream O2. sensors. I then checked for signal to #2 again and got nothing. Swapped coils with #4 and still nothing. So I went on to check all cylinders for signal. No problems with the other 5 cylinders. Then I went to ECM and unplugged line to #2. Checked for continuity between ECM plug and coil plug and it checks ok. Also checked for short to ground... it checks ok. I still get all three DTC's... guessing that the excess fuel is tripping both banks because of #2 not firing... not sure? do you agree or not? I then pulled ECM plug and checked the CKP Sensor for ohms check. It's at .630 ohms. Then plugged back in and disconnected plug at CKP. Checked sensor at .630 ohms also. Then went to EMC and disconnected plug and turned key on and checked for 12volts and 5 volts according to the book... which is a Grand Vitara... not a Vitara. I could not find a Vitara book by the way. IF you know where to get... please send a link. Thanks!
