Examination
1. Check the condition of the intermediate shaft, especially the fuel pump and distributor drive surfaces.
2. Check the condition of the teeth on the intermediate shaft sprocket. The teeth on the sprocket are symmetrical and if one side of the teeth is worn out, the intermediate shaft must be replaced.
