Check the battery terminals first to make sure they are tightened and not corroded, if you have a way to check the battery that would be good [ you may have a voltage gauge on the dash, when you first turn on the key it should register at least 12 volts, and not drop below 9 volts when cranking ], a load tester is the best way. If all these things are ok, then I would suspect the igntion switch is faulty as it seems you have no power to anything at times.

2013 Hyundai Elanta will not start, turn key , new battery, nothing, all lights n dash work, could it be the alarm system OEM


If you have a second key, try that one. Sometimes 1 key will unlock, 1 key will start. If not it would be the anti theft or security system disabling the ignition module. Which is why it won't even try to turn over.

Turn key and nothing happens. Car is dead. Lights come on on dash and headlights but car won't start


sounds like your security system failed.. its real common in gm's. I have had the same issue with one of my cars..you can bypass it. this is how I fixed it.. pretty simple.. and I have to say I have had it in my car for 5 years and haven't had an issue since.. hope it helps

I have 1992 isuzu pup truck.sometimes i turn the key to crank it and there is nothing noise wize,no clicking nothing.the dash lights come on,battery is good.i turn the key another time and it cranks r


you need an ignition switch. One way to figure it out is to turn the key to engage the starter, quickly........over and over, the "catch and start" will happen with no change and suddenly, its engaged. Or, keep the key in the START position, don't let up on it and hit the steering column with your fist, or the steering wheel. It may just be shorting out.

Car won't start, seems to have power, all lights working. when I turn the key nothing happens. this only happens sometimes


Could be a bad alternator.. It may not be holding charge. Or your starter could have failed.

Though I've had the same problem and it was a dead battery in my vehicle. Had enough power, but to keep the car on..

sounds like a dead battery to start with. Not even enough juice in the battery to energize the solenoid / brake interlock to get it out of PARK. Hope this helps

2001 SAAB 9-3 SE won't send signal to start


Is your SAAB automatic? If so, it is most likely the Neutral Safety Switch. I have had the same problem, it is very common in automatic Saab 9-3 models made in 1999-2002.

2008 nissan sentra has occasional starting issues. this has happened 4 times since we bought the car. car runs fine, sometimes will not start when key is turned. everything is dead....no lights inside, no...


Could be bad battery or Somthing going on with the main fuse box.  Another thing to check is your ground wires.  If they are loose, you can not complete the circut.
