This could be a simple problem. Remember with the new computer technology today that an electrical problem is hard to diagnose without being hooked up to a diagnosis computer, however my mother has a Trailblazer that did the same thing and it was just the battery terminals corroded at the connection. Sometimes you can't see this until you remove the connections at the battery. I hope you are able to use this and fix your problem, Roger

Sounds like an immobiliser fault.
Try another key if you have one. If you still get no joy with that, then the only solution is to take it to the dealers for a re-code or fault find, as testing of these parts is near impossible DIY.

"Warning Lights" on the dashboard of "1995 Nissan Maxima"


The warning lights coming on with the key in the on position is normal. If the key is turned to the start position and the engine will not crank over, suspect an internal starter motor problem or lack of power to the starter solenoid. You can try tapping on the starter motor with a blunt object while someone holds the key in the crank position to see if it starts when this problem occurs. If it starts using this procedure, the starter motor will be defective

How can i bypass the alarm/immobiliser on Autowatch 446RLI the car battery died, after charging the car battery the car won't start. it is dead quite when turning the key even thou the dash is lit.


Try getting a friend to boost start your battery with his vehicle and see if your car will crank. If your car cranks over - you have a faulty battery.

Check your battery leads, particularly the black earth lead where it connects to the engine/bodywork.
It's worth pointing out that a failed battery will charge up to a certain extent - however there isn't sufficient power in that battery to crank the engine even though all your dashboard lights are illuminated.
Get somebody to try boost-starting your battery first.

If you're sure that your battery is ok (or if connected to another vehicle): Put your ignition key in and turn it on/off a few times. Leave it in the 'on' position for 2-3 minutes. Give the system time to re-recognise the key

It actually sounds to be battery problem

My car started out by stalling when I put the right turn signal on but would start back up. Now it died and will not start back up has new battery. the dash lights come on but when you turn the key


Sounds like you might have wire problem.
Try turning the key to the point before ignition. This is actually a dashboard test that have all lights on the dashboard turn on. Try to see if the lights are completely bright or a bit dull in the light.

You battery might be uncharging itself, instead of charging. I have tried that. even with an only 1-2 day old battery.

Reset timing belt light on quantum 2.5 diesel


Try this: 1. Put the key in the ignition and turn it up one notch. The dashboard lights will not turn on. 2. Hold down your trip meter button next to the odometer. 3. When you are holding the trip meter button down, turn your key to the next notch. So, the dashboard lights will be on, but the car will not be started. Do not start the car. 4. Continue holding the trip meter button until the light turns off. You have now reset your Maintenance Required, or Maint Reqd, light

1996 nissan maxima wont start, windows wont roll and dashboard caution lights and icons not lighting up when i turn the key. the turn signals also arent working but they do with the hazard lights on. car...


I think your ignition switch has quit working, or it has stopped getting power. If you pull the connector apart to the ignition switch and check if there is one wire on the harness side of the connector that has power, it sure looks like a bad ignition switch. One fat wire, about 12 gauge size, going into the switch should be hot at all times. If you have it, pretty obvious that power is not going out of the switch. key on should send power out of the switch to the fuses for the windows and other accessories, and also send power to the dash for the warning lights and gauges.
Power to the switch will be either from one of your fusible links near the battery or from a maxi fuse in the fuse/relay block under the hood. The funny action of the key kind of points to the ignition switch, though. Still, check for power into the switch first.

2005 Nissan Micra start when push but not with the key and there is power


Not an expert on non-us Nissans, but there should be a clutch switch to prevent you from cranking the engine in gear.
I would check the circuit with that switch.

Lights, radio and powerdoor locks work, turn key to start car nothing happens


If you had said the radio did not work, I would say it was the key switch or a large fuse or fuseable link.
But the radio is powered thru the key switch.
The problem could still be the key switch or a major fuse, I would check all of the fuses then power at the key switch.
Also check the ground connections.

Rover Won't Start


Possibly a bad starter, need to check for power at the starter to verify. The big wire is from the battery, the small wire is from the ignition. If you have power on both wires with the key in the crank position, you have a bad starter. If you dont have power on the samll wire when cranking, then you need to test your ignition and neutral safty switches.
