SOURCE: determine hot wire color and location w/ignition on

yellow. you can splice into your factory wiring and work the same as if your ran one straight from the battery

SOURCE: bypassing starter

the solenoid has 2 big cables one goes to the battery and the other to the starter.
the small wire that has a boot that pushes on to the screw is the control to close the solenoid.unless the solenoid is shorted,the starter should not run

SOURCE: starter wont crank on a 2000 oldsmobile intrigue

Check your manual if you have it. I believe you need to have the key in the ignition in the ON position for about 10 minutes to reset the security system.

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 .

I have a 2004 Chevy trailblazer no start no crank but if I put key on hot wire the starter it will start I replace new ignition switch and new starter relay b


Before you do any thing check for loose or bad connections. Also check you ground connection to engine. Check Fuses, relay and for a Fusible Link open circuit. Now let me explain what a Fusible Link does. They are short lengths of small gauge wire installed between the Battery and the Ignition Switch, or the Battery and the Fuse Panel. They'll melt and open the circuit before damage occurs in the rest of the circuit. I hope this was helpful you.

08 Chevy Cobalt wont start. Battery is good.?


Is there a warning light , padlock an car symbol lit when it won't start ? I assume it has to be a bad starter? Every time i jump the car it starts up fine.??? It wouldn't be a starter then ! Have the charging system check out . Have a voltage drop test on the starter circuit done . Test from the starter relay . check out videos on youtube , but don't assume anything . Test , Test Test .

Starter Voltage Drop

VEHICLE RELAYS Testing from the relay base

Plus you need to know how the starter system works for the vehicle your trying to diagnose . I 'am a GM tech , Chevy , Cadillac , buick , GMC. Have access to GM factory repair info. Been to a lot of GM training school's . The computers on this vehicle have a lot to do with the starting of the vehicle ,PCM - engine computer , the ignition switch is a low voltage input to the BCM - body control module , which will send a message over the GMLAN serial data communication network to the PCM to energize the starter relay or crank relay .The PCM also has to see a voltage input coming from the transmission range selector switch , showing it's in park or neutral , has to have correct fuel enable password from the theft module etc...
Also it take's is a little corrosion , lose connetion , lower then normal circuit voltage for problem to happen .
Factory service repair manual discription

Moving the ignition switch to the start position signals the body control module (BCM) through discrete inputs from the ignition transducer that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the engine control module (ECM) requesting engine start. The ECM receives a ground signal from the park/neutral position (PNP) switch or a signal from the clutch pedal position sensor notifying that it is safe to start the engine. Ground G105 supplies ground for the CRNK relay coil. The starter relay coil control circuit is then supplied voltage by the ECM closing the switch in the starter relay suppling 12 volts from the CRNK fuse to terminal A of the starter. Ground is supplied to the starter solenoid through the engine block.

The first step in diagnosing a problem like this , hooking up factory scan tool , checking for DTC'S - diagnostic trouble code's , checking inputs to control modules that are in charge of starting the vehicle .

Testing an knowledge is the way to a fix , an testing cost $$$$$

R&r starter to 2006 cobalt ls


Park your Chevy Cobalt on a level surface, activate the emergency brake and place blocks behind the back tires for safety. Disconnect the negative battery cable with a terminal puller. Raise the front end of the car with a jack for easier access to the starter.
Remove the intercooler pump's outer bracket in models with a 2.0L engine. Place the bolt, and all other nuts and bolts, into the jar for safekeeping until later.
Disconnect the starter electrical connections, including the S-terminal and positive battery cable. Label the wires if you have concern about remembering where they go when you install the new starter.
Unscrew the starter mounting bolts and remove the starter from the vehicle's engine.
Take your malfunctioning starter to the parts store with you. Aftermarket distributors remanufacture most of the starters they sell, so you can likely obtain a partial credit toward your new starter by exchanging your old one. Be sure that you take care not to damage the starter in transit, because the better condition it is in, the more you can get for it.
Purchase a replacement starter that has the same or higher cranking capacity (power rating) as the original starter. Also, match the bolt patterns, drive gears and electrical connections. Your owner's manual may list specifications or the auto parts technician will help you determine them. Download a free owner's manual by registering with the Chevy Owner Center (see Resources).
Install the new starter by reversing the removal process. Torque the starter mounting bolts to 37 foot pounds (50 Nm). Tighten the bolt for the intercooler pump bracket to 15 foot pounds (20 Nm).
Lower your Cobalt back to the ground. Reconnect the negative battery cable. Turn the key in the ignition to see if your new starter motor functions correctly.

How to install a remote car starter


The remote start should come with instructions, you will need these especially for the diagram of the units wiring harness.  It will need to be wired into the ignition key on wire, the ignition starter wire, power and ground, and usually the brake light wire, and a hoodpin disable switch that will come with the unit.  Also most manufactures will have a website with vehicle specific details like color and location of each wire on the vehicle.  hope this helps.
