[QUOTE="ford_racer, post: 8768247, member: 33480"] Did you not read what I said? Any could mean transmission related, chassis related, alignment related, etc. I work in a parts store and get people asking for code scanners because their car shutters when they brake, or it pulls to one side. As for what you said, code scanners will not immediately diagnose why your car does not start. It reads codes off of sensors. Does a Saturn SC1 have a sensor that reads when a fuel pump is not operating sufficiently? No. Therefore, if the OP's gf's fuel pump is going out, a code scanner will not do anything for him. I cannot remember off hand the coil setup on the car, but if it has one coil for all the plugs (which it most likely does), a code scanner will not pick up the fact that the coil has gone dead. If it has multiple coils, like GM 3.8s do, a code scanner will read that there is a misfire in one or two cylinders, but it will not directly point to the coil. The bottom line is that while code scanners do make it easier, they only narrow the problem down but do not always directly point out the problem. There is still a bit of diagnosing to do on many problems. OP, go to a parts store and ask for a spark plug tester. If I was at work, I'd give you an O'Reillys part number and price, but I don't work until tomorrow. Another way to test is to pull out the spark plug, reconnect the plug wire, and ground the plug via the ground electrode and have someone crank. If it does not spark, then there's no spark in that cylinder. This isn't fool proof however, as it may be difficult to get a ground. [/QUOTE]
