Alrighty I will first admit to my dumb@$$ move, Sunday I changed out my ignition module and spark packs WITHOUT disconnecting the neg lead. But it started. Of course Monday when the wife had to go to work it won''t start. checked out no spark on any plug, replaced ignition module AGAIN, got spark engine almost starts. Looking at crank sensor or at a far reach timing chain. Can you help??

Well, no comment as to the year/model, or any failure codes, so it is simply a guess that the crank sensor is failing/has failed ...

this is a 2002 saturn SC2 3 door coupe with 135,000 miles on it


Can you see a trend here

Thank You for your info, I went ahead and changed out the crank sensor as well. the results were the same so I decided to step on the gas, it seems as thought the engine was flooded. But for further reference the vibration my wife was feeling in the brake pedal disappeared. I believe this was due to a failing crank sensor.
