Check you lead's on the battery first,
then check you postive lead from the battery to the starter, to make sure none of the leads have come loose.
if they are ok, it will be the ignition switch need changing.

2001 Cadillac DTS wont start or turn over


Turning ignition switch to start position ! Nothing happens , no click , nothing ?
Circuit Description
Moving the ignition switch to the CRANK position sends a 12 V signal to the PCM Ignition Crank Sense. The PCM verifies that the transmission is in the PARK or NEUTRAL position. The PCM then grounds the control circuit of the START relay. When the START relay is energized it allows voltage to the starter solenoid S terminal.

Starter Solenoid Does Not Click

2
Turn the ignition to the START position.
Does the engine crank?
YES - Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
NO - Go to Step 3
3
Install a scan tool.
Turn ON the ignition, with the engine OFF.
With a scan tool, observe the Crank Request Signal parameter in the PCM data list.
Turn the ignition to the START position.
Does the scan tool display Yes?
YES - Go to Step 5
NO - Go to Step 4
4
Turn ON the ignition, with the engine OFF.
With a scan tool, observe the Crank Request Signal parameter in the PCM data list.
Turn the ignition to the START position.
Does the scan tool display Yes?
YES - Go to Step 11
NO - Go to Range Selector Displays Incorrect Range in Automatic Transaxle - 4T80- E
5
Turn OFF the ignition.
Disconnect the Starter relay.
Turn ON the ignition, with the engine OFF.
Connect a test lamp between the battery positive voltage of the Starter relay coil circuit and a good ground.
Does the test lamp illuminate?
YES - Go to Step 6
NO - Go to Step 19

This is troubleshooting info from GM factory service testing and repair manual .A scan tool isn't necessary , you could use a test light if you knew which pins at the PCM . For example , testing Crank Request Signal parameter in the PCM data list. Find this wire circuit at the PCM , with a test light .When turning the key to start position ,does the test light light ? A factory scan tool just cuts down the time of diagnoses . A wiring diagram is a must for diagnosing this . Free wiring diagrams can be found at
http://www.bbbind.com/free_tsb.html There are videos on youtube on basic automotive electrical trouble shooting , Control module diagnostics . That is if you don't know how to already .

Use a 12volt test light and connect to the starter energiser wire, get someone to turn the key and see if the test light comes on, if no then the starter relay has packed in. A further test you can do, but YOU NEED TO BE CAREFUL, set car in park DON't switch the ignition on, and direct feed the starter to see if it cranks the engine, if yes you are back to the starter relay.

When I turn the key nothing happens. No clicks, no crank. All of the lights work properly. No dimming or turning off when I try to start. This has happened a few times before. The first time I put the car...


Ignition switch....the electrical ignition switch. To verify, find the thick white wire in the harness coming from the switch and do two things; first, check for power at this wire, when you switch the key position to start. If nothing, power the wire momentarily with the key in the run position, and your car should start.

My 2000 honda civic wont turn over and has no spark but the ignition coil and modual are both fine


Won't turn over? Do you mean the starter won't crank the engine over?

Or the engine cranks over and won't start, and you have tested for spark when cranking and have no spark? And then you have tested the coil and ignition module, and they tested out good? Am I on the right page here? If so, maybe the next thing to check would be the crank position sensor. The ecu (computer) signals the ignitor (ignition module) when to initiate spark after it digests the signals from the crank position sensor and the cam position sensor.

Key turns fine. Car won't turn on. Won't even crank. Sometimes pushing key further into the ignition switch with a bit of pressure helps. Battery is one year old.


What you are saying is the key switch is worn out, and there is a separate problem with the engine performance.
Either an import shop or the dealer are your options here.

MY 98 FORD EXPLORER CRANKS BUT DOES NOT TURN OVER. I HAVE POWER BUT MY VEHICLE WON'T START


You mean that the starter is turning (cranks) the engine but the engine won't start? Be sure it is getting fuel. Turn the key to the on position and you should hear the fuel pump in the fuel tank run for a few seconds. If so that is good. If the fuel is being delivered then possibly you have no spark which usually is the electronic ignition module. The only way to test it is to replace it. Your timing chain or belt could be broken or "jumped" as the third possibility. I am leaning toward ignition module being bad as they just die without warning and nothing can revive them.

Ignition switch maybe ? Do you know how to do automotive electrical testing with a volt meter ? Pull the covers off the steering column to get at ignition switch electrical connector , then look at a wiring diagram to see which wires should have B+ voltage in the on - run position ! See if the B+ voltage drops out or just isn't there . You can find free wiring diagrams here
http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine . Under system click electrical distribution ,then under subsystem click on power distribution .Click the search button then the blue link . scroll down the diagrams till you see any that show the ignition switch . Check all the wires that should have B+ power in the run position . I know GM has had ignition switch issues .
The starting of the vehicle is computer controlled ,when you turn the key to start ,this sends B+ voltage to the PCM - engine computer which will then energize the starter relay ,thier by cranking the engine .
