My 1999 integra with under 150k started stalling while mostly at stop sign or cruising towards one and won’t start for ten minutes or so. One time when it happened, I was on 35mph road but I do not remember if I released the accelerator momentarily. Once it stalled right after starting. Mostly stall…

This acts like a possible bad cranskshaft position sensor (cps). Works when cold, dies when hot, restarts cold and sets no codes. When it dies, try starting it with starter fluid. If it runs, it is not the cps, it is a fuel problem. If it doesn’t, and you check for spark and there is none, suspect …

Crankshaft position sensor could very well be it, but there may be more than one heat-sensitive component in the ignition system. As I recall there is something in the distributor, too, on my 1999 Honda. Also something that detects fluctuations in the crankshaft rotation speed.

When this happens try taking off the gas cap, see if there’s a vacuum. If there is, try starting. If it starts, there’s something wrong with the fuel vent system.

Thank you all and will work on those recommendations. BTW, nearly 14months ago, as a result of dirty IACV, my AC clutch disengages at idle speed when the car is warm. AC clutch back and forth tries to engage but unsuccessfully resulting in a tik, tik sound (at idle and the car is warm - RPM drops …

The next time the engine will not start, open the throttle while cranking the engine.

Check to see if there is spark immediately after it stops running. It could be a weak igniter. Otherwise use a scan tool to see what’s going on when it stops running. Running out of gas or suddenly disconnecting the spark plugs or similar incident won’t trigger the check engine light.

No, he means when it dies, open the gas cap and see if it will immediately restart.

Yes @Nevada_545 - I was also thinking of it. You hit the nail on the head with the AC issue https://community.cartalk.com/t/tik-tik-sound-soon-after-dont-have-to-be-cold-start-starting-the-car-and-goes-away/169063
