Re: problem with '93 camry 4cyl

how did you determine that it was the ignition coil on your camry. My son has a 1992 v6 camry which has been running great and then one day it died going through an intersection and would not start again. It cranks like mad but I have no spark at the plug. I checked the ignition coil resistance and found the secondary resistance to be a little high 12.2k ohms vs 10.4 max spec. So that appears to be a source of a weak spark but not NO spark. I tried to check the resistance of the plug wires but get an "open" reading. No way that 3 of the 3 plug wires I checked could all have failed at the same time. I think they are silicon, do you have to measure resistance differently. I measured the resitance of the igniter but do not see a spec anywhere. Any help.

Final diagnosis on my 1990 Camry 6 cyclner. IT turned out to be a bad coil and the rotor was cracked nearly in half and burnt very bad. Never seen a rotor die that bad. Not sure why the ignition wire resistance read so high but I guess it must be related to the amount of voltage my voltmeter uses to determine resistance and the very high resistance of the wires to prevent radio noise. Anyway, put everything back together and it cranks... and even runs like a champ. One item to know... my manual says there are two bolts to remove to get the distributor off.. and in fact there are three. So that cost me a distributor. Also, take care not to damage the ignition wire holders that attach to the distributor. They are $6 each and not carried in stock by the Toyota dealer. Also when you go to order them, take your VIN number as 1990 was a split year for two different configurations of the ignition wire holder.
