My engine shut down and would not restart. I have gotten the following fault codes (level one code)(25) High wter temp sensor reading,level 3 codes )81,82,83,84,85,86)- open in #1 thru #6 ign coil. Are the 2 sets of fault codes related? Are the coils showing open because of being in the test mode, or that the engine is not running? If it actually got the high water temp reading why didn't the "water temp" light come on instead?
