Well this morning I had spark and now i have nothing after I retimed the car cause that needed to be done also. So after we retimed it now I have nothing in the spark area . I hooked a test light up to the dizzy will cranking with a test light and it was very faint. This morning it was fine the car was running but was backfiring so i redid the timing but theres no spark now. What are things I can check for possible ground came loose?

Oh the motor is a d15b bottom and and a z6 head . The distributor is a z6 and im running and unchipped p28

 

Did the timing belt snap? If not, check the coil in the distributor.
