i keep gettin 4 and 8 flashes on my ecu which is crank sensor and tdc seonsor. both have to do with the dizzy but ive changed the dizzys alread but i am using the same ignition coil so would the ignition coil b the problem? any help would b great

 

Check the plug on the harness side. Get a meter and check continuity from the plug at the ecu to the plug for the distributor in the engine bay. It prolly has an open or the plug is jacked up.
