Engine Dies Intermittently, Main relay question

Recommended Posts

I have been having the same problem as many others with my 93 Accord 10th Anniversary.  It dies intermittently, then will sometime start back up before I come to a stop without my doing anything (kinda like popping the clutch in a manual) and sometimes I have to crank it for a while before I can gt it to start.  I have replaced the ignition switch as that seemed the most common issue, I pulled apart the old one and the contacts were black, but not really pitted.  I have seen a number of posts regarding the Main fuel relay, but I am wondering how the vehicles dies when it is a fuel relay related problem.  My car just cuts off like a switch was turned off, leading me to believe it is electrical, rather than fuel.  What happens when the relay fails, does the engine sputter a little, or does it simply switch off?  I am planning to replace the coil and igniter next, but will wait to hear what you guys think about the relay possibly being the culprit.  I should also mention that the problem only occurs in cold weather, and especially when the engine/car is cold.  Once the car has been ruinning for a while, the problem goes away.  Could this be related to the distributor?  Maybe a crack/condensation? Once the condensation evaps off, engine is ok?
