After changing the timing belt the emegency electronics light comes on after 5 starts. left overnight the same sequence starts again (5 starts and the light comes on for the rest of the day) Checked the belt and timing again and found no problem, reset the fault light and started the car 4/5 times and the light came on again. I can reset the fault light by switching the ignition off and back on again as the car is being driven (2/3 mph is enough). Car runs ok, petrol consumption ok @ 40mpg. Any ideas, we are all stumped.
Well if you used a scan tool to reset the engine code light then you can use it ti find the problem just read the results from the scan

One question, have you replaced the ECTS (Electronic Cooling Temperature Sensor)? These cause no end of different seemingly unrelated problems on Saturns. Peice is about ten bucks and is an easy install. Just search on youtube for a how-to video. Even if that's not the problem it is reccommended to replace this peice just the same as they ALL end up going bad at some point.
If that's not a fix, start pulling plugs. Check to see if they're correctly gapped and if they have any damage/corrosion. If you're running Platinum plugs, immediatly change to a copper plug as Platinums have no place in these motors. Most people have the best luck with NGK copper.
Check to make sure that your plug wires haven't been crossed. This sounds like a plug or wire issue most likely so it has to be in that family, if the plugs are good, wires good and not crossed, sensors are fine, then time to replace your coil packs. If you've replaced everything up to the coil packs then that is most likely the cause of your dillema.
