1994 nissan altima will not start...

Probably the starter. Which if is not the funnest job. There is the possibility of a poor connection, but that's still a little tough, and not really likely.

I have a 1992 Nissan Sentra with much the same problem. I replaced first the battery, then the starter...but the problem persists. As far as I can tell, it is either the switch on the clutch that has to engage or the ignition interrupt relay. The latter item is a dealer only part, and, I have not had time to check out the former. Maybe this weekend. In any case, with the Sentra, sometimes releasing the clutch and re-applying it will make the problem go away. Sometimes jiggling the car a bit takes care of it. This seems to be a recurring problem with Nissans of that age, as I have seen a number of posts listing these same symptoms. Good luck, and, if you find out the answer, Please post it here to help EVERYONE. Regards Dave Mundt

Hi. I thing it is Lambda Sensor problem. You shoul replace them.

1. When the engine is cool - then starts, but when is hot - cant start.
2. Engine works properly by high RPM. But not work properly by low RPM.

Is that right? If yes, its a bad Lambda Sensor for 90%.

Check the grommet on the clutch that allows the selonoid to be engaged to start the car. The grommet may be broken or missing allowing the clutch to not engage the selonoid. Grommet is black from the factory, replacements are clear.
