Strange behavior

1994 Mazda 626 runs great when the weather is cool, but when it's hot and humid (90 +), the car will go dead when you stop the car. 02 sensor? Any ideas?

Go dead as in the starter will not turn the engine over?

RE: Strange behavior

The starter will turn over, but it fails to crank immediately. If it sits for a few minutes. It will crank again.

RE: Strange behavior

Hard to say. When you shut a car off it actually gets hotter since the coolant is no longer circulating. I would check it for codes but those were notorious for distributor problems. The hotter a coil gets the more resistance it has so it is something i would check. Could be the fuel pressure regulator/fuel pump.Lots of things can cause what you describe. It can be very expensive to guess on that problem but i have never seen an o2 cause a nostart condition.
