I was checking to make sure that I had spark coming out of the #3 spark plug and when I determind that I did i put the spark plug wire back on the plug, as the car was still running, i gave it a little gas and then it shut off... Now i have no spark at all any sugestions. it is a 1993 saturn with duel overhead cam... Thanks Spoonman

this will fix 95% of no spark problems in saturns
take all four wires off the coil pack, disable the fuel injectors(pull the fuse). have a second person to crank the engine, there should be a spark tower to tower (two on the left side and two on the right side). if there is, check the order of the spark plugs, it should be (left to right) 1 - 2 - 3 - 4 on the block, 4 - 1 - 2 - 3 on the coil pack. if there is no spark, check the DIS fuse, if it is good, then the crank sensor is bad.
