(is not your engine but is all I have access to) Does not start. Possible cause, suggested repair a. Ignition control module malfunction. Install Siemens ignition control module. b. Formed hose between idle speed air valve and air guide housing fallen off due to backfire. (?) Test air flow potentiometer position. Check rest position of air sensor. Center air flow sensor plate. Check rubber hose between idle speed valve and air guide housing for tight fit. Replace if worn or swollen. sorry I don't know more about your car.
