97 maxima won't start, battery, alternator, and starter is fine, had check out. Car starts during normal/low temp. outside but when it get hot(high temp.) outside it just turns on at the dash. If I press hard and shake the key after several annoying attempts it will finally start. Is it a bad ignition switch? Starts smooth during low temps!

Could be several things that caused car won't start, inculding starter, ignition, dirty or loose battery connections.

A couple of thoughts: Test the alternator charging output and make sure it is operating normally. You didn't mention what happens when you try to restart, does it crank over normally or not at all? If your vehicle is high miles, which would be normal for a 94, you could have a bad starter. I have seen starters with worn bushings crank OK when cold, but when hot, the armature will drag and cause low/no cranking speed and an excessive amperage draw from the battery. Starter draw can be tested. I would suggest going to a parts store, such as Advance where you can have it tested, probably for free. Have them test battery, alternator output and starter amp draw, then buy what you need.

Well, you DO have a dilema! First, if the battery is internally shorted or run completely down, it is NORMAL for the alternator voltage to read a little low - at least until the battery is at full charge. The best advise I can give you is to read these articles:

My Car Won't Turn Over

From your description it sounds like the car will start when it is warm out ? I would start with the air temp sensor which regulates the air /fuel mixture on start up.Unfortunately,if I remember correctly, the air temp sensor is built in with the MAF sensor (Mass Air Flow) and you will need to replace both of these to start.Try your local wreckers for a low mile one.Good Luck

Could be a bad switch but heat usually doesnt cause this. A starter can be affected by heat tho

It sounds like an engine temp sensor is open.. When your engine is cold or anti-freeze is cold your ECU or ECM gets a signal from the temp sensor for cold engine start. It would make sense that it works fine when hot because the resistance on the sensor is a lot lower. Take an ohm meter if you have one and check the resistance across the temp sensor pins. When the engine is cold the resisitance should be really high. Start and warm up your car to normal temp and check it again. It should be a lot lower now. If not replace it. Hope this helps.

YOU NEED TO CHECK COOLANT LEVEL.AND CHECK THERMOSTAT.WHEN YOU FIRST START YOUR CAR UP IN THE MORNING .WHEN IT GET OPERATING TEMP.RUN ABOUT 5 TO 10 MINUTES.FEEL TOP RADIATOR HOSE AND THE BOTTOM RADIATOR HOSE.IF BOTH HOSES IS HOT THERMOSTAT GOOD.IF TOP HOSE IS NOT HOT BUT THE BOTTOM IS REPLACE THERMOSTAT.THAT CAUSING ENGINE TO GET HOT.IF ALL IS GOOD.CHECK WATER PUMP WEEP HOLE.IF LEAKING REPLACE WATER PUMP.CHECK COOLING FANS.MAKE SURE THEY ARE RUNNING.IF NOT CHECK FUSE AND RELAYS.

Hello, I would assume this is a starter problem. You can go to Autozone and get a free diagnostic of your electrical system for free and tell you if your starter, alternator, battery is bad and/or if you have any trouble codes present in your system. I would also check your battery connections to see if they are tight and I would also check and see if your starter cables are tight as well. I hope this helps you and Good Luck!

If this just started to fault after battery replace, I would suspect a vacuum hose or outside air temp sensor got unhooked or damaged under the hood. A scanner could help diagnose issue if nothing obvious is found to have been disturbed under the hood during batery replace.Good luck!
