Greeting!
I own a Chevrolet Caprice Classic Bougham 1989 and it won’t start. In the beginning it ran just fine, then it started running rough and would stall occasionally. It would start right up and I could continue to drive. Then it stalled again one day and I was not able to start it back up. Had to tow it back home. I noticed I don’t have spark at the plugs. I do have spark at ignition coil. Fuel injectors are spraying and the engine is turning over. I replaced the following parts:
Spark plugs
Ignition wires
Rotor & cap
Ignition coil
Ignition control module
Distributor

After I replaced those parts, still no spark. I also suspected it could be a ground issue, but couldn’t find anything. I don’t know what else to do. I would be grateful if I could get some advice!
Kind regards,
Ville from Sweden
