Nissan maxima 2000, related ignition switch but still as soon as battery is connected the relay clicks (near battery 3rd one) and tries to start the car without even key in the ignition...

Two relays must close. One for security system and one for neutral safety. Check both circuits. Is there a security light flashing?


Do It Yourself Diagnosis and Repair

does the car turn over or do you get nothing at all...cos your ignition switch could be bad....it takes me five minutes to start my 95 maxima up cos of this problem..

sounds to me like you need a new ignition switch. not the ignition in which you put the key into but the switch that is mounted to the back of the ignition switch. there is a white round switch mounted to the back of the ignition cylinder. I thing it has a problem. so you don't need the while ignition cylinder, but the electrical portion of it only.

it might be in your ignition still try turning it from the first click acc to stat and dont stop on the on position thats how mine is

it is one of two things.

• the starter is either worn and brushes not making contact or an engine oil leak onto the starter. thus keeping the brushes from making contact you can check this by banging on the starter while someone trys turning the ignition back and forth to start.(making the click click click)

• ignition switch is weak, not providing enough voltage from the to kick the soliniod all the way to start the starter

The way to check that is to hot wire the starter soliniod little wire, to battery voltage. (the big cable on the solinoid)
If it turns over good, then you can either replace the ignition switch or install a relay someware near the starter to supply it with propper current to kick the solinoid all the way to engage the motor.
The relay acts as a remote starter switch that feeds more direct power to the starter solinoid.Now the only thing the ignition switch is responsible for, is trigger the relay.

It could be the ignition switch, neutral safety switch,alternator, ignition/starter relay, ignition coil/module.

Please check for loose ground wires. You should see these wires connected to the engine and the body of the car. There are several of them. Check each of them. You may also want to check the cables to the ignition coil or the ignition coil if it is working

put key in trunk and pop it try this it may work

check first the ground connections and the terminals if they are loose. Check also the starter relay and its cables. Have the starter capacitor checked. If that does not resolve it go to the starter motor and have it checked.

Sounds as if you need the electrical portion of the ignition switch. The contacts inside are most likely worn out.
