My fiance has a 93 Del Sol Si with the D16Z6, a five speed and 199,000 miles. About two weeks ago it woludnt start at all. Replaced the coil and Ignition module. She drove it for about a week and it would miss and the tach would jump all over the place. Now it wont start again and I replaced the plugs, wires, dist cap, rotor, and another ignition module. I would like to get it fixed soon because she is driving my Cadillac. Thanks

 

sounds like the distributor to me check the ecu codes and see what code it is throwing

 

bouncing tach= bad ignitor
