Sparky 2,068 Report post Posted March 9, 2010 When did it last run? Has any work been done on it lately? Where did you check for a spark - at the plugs, or have you also checked the coil?

freshcut 0 Report post Posted March 9, 2010 Unfamiliar with the S3's, but do they use electronic ignition? If so, you might possibly have a failed ignition module or pick-up coil. I've had ignition modules intermittently fail. Work fine one day, bad the next, and again working the day after. Quote Share this post Link to post Share on other sites

freshcut 0 Report post Posted March 10, 2010 (edited) You generally have to have it checked on a machine. Most local chain part stores have the equipment to check the ignition module. You might call around to a few. If you're in the States, most Autozone stores can check the module for you. Edit: checking the pick-up coil can be done using a standard ohm meter connected to the two leads of the pick-up coil. You'll have to check the specs on what your resistance range should be on the coil.....but I can tell you that if you get very high or very low resistance then the coil needs replacing.

molemot 518 1 Vehicles Report post Posted March 10, 2010 The Lucas ignition system has a three pin connector in the lead from the electronics to the distributor trigger.This often corrodes and then you get no sparks! Well worth a check. See if you have sparks from the HT lead from the coil...if you can get sparks from there, it's a distributor cap/ rotor arm problem; if not, then you're into the optical trigger, the 3 pin connector or the sparks box itself. Unlikely to be that, though, as I'm still using a spark box that spent months under water!!
