Question about 1991 Lexus ES 250
The ign. coil is RARELY the cause of no spark, although they do indeed fail. your car has electronic engine management, which includes ignition and fuel management (fuel injectors) Before you spend a lot more money "throwing parts at the problem" and still no results, do some diagnostics. Start by drawing the diagnostic codes stored in the computer. The resulting codes will tell you what system(s) are out of range, or non-responsive to self tests. This will tell you what SYSTEM or CIRCUIT have failed, NOT necessarily the specific component. Get into the diagnostic mindset: What does it take to make the engine run? (Fuel, Air, & Heat) Any one of the three missing, or not timed correctly, there will be no BOOM, and engine doesn't run. Look for the things that will cause your failure, not ANYTHING that you see wrong. For example, an oxygen sensor is certainly going to have some bearing on how well your engine manages fuel control, but it WON'T stop ignition (or fuel for that matter). Go here------> http://autorepair.about.com/library/ts/obd-i/bl-dtcs-36.htm and follow the procedure for drawing the codes, and if you are unfamiliar with the process or fundamentals of electronic management, use the repair manual for the diagnostic "trouble-tree" to diagnose and correct the failure. If you haven't a repair manual, you can usually buy one for < $20.00 at a parts store or book store. If money is an issue, or you can't locate one for sale, go to your library in the REFERENCE section. Also available at most libraries these days is a computer-based repair resource called Mitchell On-Demand or ALLDATA. This is professional level information. You can also subscribe to either of them for a single vehicle for an annual subscription here----> http://www.eautorepair.net/ http://www.alldatadiy.com/ Good Luck.
