The switch can be tested with a multi-meter to see if it is the problem. The switch will have a hot at all times wire going into it. If the switch has power out on the start wire with key held in crank, or if there is continuity between the power in wire terminal and the start wire terminal (on the switch side of harness connector) when the key is held in crank, then the switch is good. Check the neutral safety switch, then the starter relay, then the starter solenoid for a fault. You may need to see a wiring diagram to find the color of the start wire coming out of the switch. A single wire from switch to the neutral safety switch and on to the starter solenoid.

It could be a loose wire or connector, defective or dirty contacts in the lock cylinder, broken wire coming from the lock cylinder or a temperature sensitive module to name a few things.

If this happens only when the temperature is cold, it could be a leaking Fuel Pressure Regulator (FPR), or due to lost pressure in the fuel lines due to cold, in which case you may have to replace the fuel pump / fuel filter / clean injectors.

The best way to diagnose this is to actually take it to a mechanic and have him check for you.

Hope that helps! Should you have any further questions, please post them here.

SOURCE: 1996 cadillac deviile want start,I checked

First off OBD 2 system which is in your car.will operate in closed situation which means although car may not run properly it will crank over and start as long as spark, fuel and air are present...What I suggest is to first check the voltage of battery..( It sounds like you have already ruled this out)If batterry has checked out good the next step I would do is check your fuses (there is a fuse for the ignition,this is probably blown....) If that checks out ok check the cable that goes from battery to starter making sure connections are tight...If all apears ok I would hook up a remote starter switch to starter followoing mfrs instruction and see if your vehicle cranks....If it does place the vehicle in neutral and try to start normally .. if it starts in neutral or any other gear it is your neutral safety switch.... I would actually try this first because it is a much easier procedure...I hope this fixxes your problem....Good luck!!!

1992 nissan maxima se 3.0 L new starter, solenoid, all relays, ignition switch still wont engage when jumping solenoid just bendix sound if I use ignition sw.wont do nothing help plz


If the starter works on the bench and you are manually energising the solenoid (to the little terminal) then it should work on the car if the battery is good and all the wiring and ground connections are good.

Shorting the two large solenoid terminals will just switch on the motor without engaging the pinion.

In your position I would have fitted a temporary starter switch until I found time to sort the problem out.

I suggest you remove the column shroud to expose the ignition switch wiring and bridge the supply to the starter terminal and if it starts the ignition starter switch (or the internal drive) is faulty and if it doesn't there is a wiring problem between the switch and the starter.

Sounds like the ignition switch, but it could be any of your other guesses too. When you turn the ignition switch do the accessory lights come on? If not, definitely the switch. Do you hear a faint clicking noise (the spark plugs igniting)? If so, it could be starter or the solenoid. It oculd also be the switch that allows the engine to start because the clutch is depressed (or the car is in park). if that switch is bad the car won't start because it thinks its in gear. Also be sure your battery is in good shape. It could be that after a short trip the battery isn't charging enough to start the car. You can test this easily next time it happens by checking voltage across the battery. It needs to be at least 12 volts. Anything less and the car probably won't start.

Hi there skate4life! The two thing that could be causing this is the starter or the ignition switch in the steering column. If you have a test light turn the ignition switch to the "on" position then test the hot wire on the starter. If it lights up the starter is bad. If it doesnt light up it means that the ignitions switch is bad and is not sending power to the starter. i hope that this sheds some light on your situation. Please leave positive feedback if this solution helps.

Have a good day!

THE NEXT TIME IT FAILS MAKE CERTAIN THE CAR IS IN " PARK " OR OUT OF GEAR SET THE EMERGENCY BRAKE,WHILE SOMEONE IS HOLDING THE IGNITION SWITCH IN THE START POSITION & MEASURE THE VOLTAGE AT THE BATTERY & AT THE STARTER SOLENOID OR RELAY, IT SHOULD READ 12 VOLTS AT THE BATTERY , IF THE VOLTAGE IS THERE, YOU MIGHT TAP ON THE STARTER { IGNITION SWITCH STILL IN THE START POSITION. IF TAPPING THE STARTER MAKES THE STARTER WORK THE STARTER NEEDS TO BE REMOVED & CHECKED & OR REPLACED

I think my starter motor has gone? my car wont start unless i pus it and kick start it in gear. Is it the starter motor gone or battery playing up??


hi...

both may be the reason for not starting.

11.please check the terminals from the battery,wires and all in good order.then check the volt comin to the starter motor if the volts are correct then the problem is with the started motor. please service or replace with the new motor.

2.if no supply is comin to the motor terminla then ther is a problem with the wires.the wire is damaged so no power goes to the motor.

3.if the voltmeter/multimeter reads less reading then the problem is with the battery.the charge is not sufficient enough to start the motor. please recharge or replace the battery if required.

if my information was usefull please vote

I guess what your doing is disconnecting the battery to stop the starter from grinding, on the starter solenoid sit on the fire wall there a small wire that just plug's into the solenoid that wire come's from the ignition switch, disconnect it connect battery if starter till stays engage it's not the switch it's the starter, also try checking voltage at that small wire should only have voltage with key to start only, also try hitting the starter some time that will disengage it, but more then likely bad starter, good luck, hope this was very helpful.

1994 ignition problem, battery is charged, sometimes starts when key is turned sometimes does not. I am not sure if it is ignition switch or elswhere.


Could be ignition switch, battery/battery connection, starter, starter solenoid, or starter relay. (phew!) Remove your battery cables and clean the posts and terminals. (There's a really cheap and easy-to-use tool for this that works VERY well. Cheap as in 1-2 bucks.) Get your battery checked, too. Just in case. If you're pretty good with stuff like this, remove the ignition switch and hotwire it. If it starts every time, it's your switch. If not that, replace your starter relay. Cheap and easy. If not that, Get your starter/starter solenoid checked at a parts store for FREE. (You'll have to remove it, but most can DIY.) Good Luck.

Won't start


there is no sensor that controls the starter motor, i suspect the problem lies with the ignition switch, there will be a single thin wire going to the starter motor, this needs to have battery voltage at it when you crank the ignition switch if you do not have battery voltage there then check it as it comes out of the ignition switch, i hope this helps
