1997 Saturn SC2 Q&A
1997 Saturn SC2 Question: Coil/Module?
Engine was running real rough and concluded #1 and #4 cylinders were not firing, however, #2 and #3 were firing. I thought that since there is 2 coils, that the coil was bad. But after replacing it, same problem. I switched the coils and still no spark to #1 or #4. Could the module be bad? Would it make just 1 coil fire or is it the computer? Service engine light is on, but I am not very familiar with Saturns. Please Help!! - mgreene
The module could have failed. I have repaired GM cars with a partial Ignition Module failure, so it can happen. - dandd
Not really sure either. But Autozone and some other part stores can test the module. It's pretty easy to take off. If 2 of four are firing and 2 are not I would say the module, coils or wires are the problem. If you already changed the coils then I wouls say test the module and replace the wires. - vegas dave
Hello. I have a very similar problem. 2003 Saturn ION. Cylinders 2 and 4 (going from left to right) are either not firing at the right time or not firing at all. The car would drive fine but suddenly stall at a stop light. Starting would take 2-3 tries then it would be fine and would run fine. However after this happened I came home and the engine was studdering. Took off the ignition module (rectangular black with four rubber tubes) and cylinders 2 and 4 were quite built up with carbon. Checked the plugs and both plugs were missing the piece of metal (L shaped) that sits at the specified distance above the electrode. Replaced the plugs and it worked fine for a while, however car began to stall at red lights, took 2-3 times to start. Tried to start it today, it started ok then ran for about 30 seconds and stalled. Any suggestions? Thanks! - Visitor
Ended up at the dealership. Computer was bad. Recently, the car was rear ended and totaled! Insurance and settlement covered all costs, including a another car! - Visitor
The engine will turn over without a problem but will not fire, could the ignition module be causing this? I've tried two new coils and it still would not fire.
2 weeks ago my car started having problems starting, all lights and radio work, no click, no noise... just wont fire. It always fires in the morning, as a delivery driver, will not start after runn...
