Pulled the valve cover to verify no 1 at tdc. crank at no. 1 dist. at no. 1.
Have compression on all cylinders. Code 12, spark is blue in bypass mode, noid light blinks
Had control module tested at Auto Zone, had AZ test mod 5 times to prove unit. passed. pick up coil is new and passes testing.Injectors are new. am now going to the egr valve. Theory ? Stuck valve and or not seated, allowing positive pressure in the plenum. Noticed vapors or smoke emiting and slight outword pressure at the intake end .
I refuse to give up I refuse to give up I refuse to give up. This has been them most challenging vehicle I have ever come across. replaced spark control
