Having trouble getting my SR to run after my rebuild. Checked for codes and am getting the cas code 11 on the ecu. Im pretty sure I installed it correctly, and don't want to buy another one if I know the problem isn't going to be fixed. Is it common to have to replace the cas or should I try something else. I got 90's on all cylinders on first start up. Second start with oil in the cylinders I got 115, 115, 122, and 130. On the last check I got 140, 135, 140, and 165. Now this is a rebuild so the rings might not be sealed. Appreciate any suggestions.
