What causes a 1988 Chevy Beretta to have no spark?
Bad coil Distributor cap Rotor
In my personal experience, two common reasons for no spark on a 1988 Chevy Celebrity are: The crankshaft position sensor has failed. The ignition module has failed. There are the usual other possible problems including failed coils or bad spark plug wires Also it is possible that the engine computer has failed.
i found one in the gm corsica/beretta 1988-96 Chilton repair manual. The manual costs about $20 at Oreilly Auto Parts, or any other leading parts store. I recommend these manuals to anyone working on a vehicle. It tells you step-by-step instructions on just about anything on the entire vehicle. It has helped me hundreds of times.
