HELP ME PLEASE. My '91 Accord EX gets no spark when the outside temp is less than 40. When the temp is above 40, it starts as soon as I turn the key. It has all MSD ignition components. MSDtech says nothing of theirs is temp sensitive. Honda mechanic does not know what the problem is! He has no experience with aftermarket mods.

 

I remember on my car having a problem with the stock distributor and igniter. Assuming you have the stock distributor, then you probably have the stock igniter module inside, which I think I remember there was a problem with. If you have a manual, I would check each component individually. You usually need to check resistance and voltage, so a multimeter is all you should need.
