SOURCE: vehicle is nonresponsive

Check all fuses and switch relays that have the same numbers to find a dead relay.
Sounds like the battery died in the keyless entry as well as the battery in the car - but that is unusual unless you left the lights on or something and your keyless entry was already dying.  When you turn ignition key on do you hear a click from the relays?
More input would help.
Could be the mechanism in the lock in door where, when you unlock door with key, alarm is deactivated - this switch or the wires in the door-jam have cracked possibly from the door opening and closing especially in cold weather like here, in Canada - so your theft system is not getting that signal that the key is turned to unlock. Check the wiring by opening the black sheath in between drivers door and the car-body between hinges - slice and remove sheath if necessary - check these wires carefully as the plastic may still be good around the broken wire.
Test the battery - try a boost!

Remove Positive battery post from car for 12 hours and then replace to reset ECM.
Check the ground wire from the battery to the body and perhaps run a temporary ground to the body from the battery to a bare spot or clean bolt, and then switch from the battery negative to the engine to see if any lights activate as a bad ground to the body.

At the Starter - there are usually 2 or more wires that group together from the big post into more wires (is live (positive) - there are black gummy-bears on these lines that are fusible links (remove positive battery post) and test with an ohmeter between each side of the black gummy-bear - if no ohmeter is available put a 12 volt light on some wires or run through a 12-volt battery or charger (wires must be removed from starter to prevent power from going through system to confirm that unit is good) you can then test these fusible links in that way.
 
Next perhaps I would remove the power Distribution Center (box with fuses and relays you already switched and eliminated as problem) next to the battery usually and check the wiring underneath it and wiggle the harness connections to see if anything lights up. being careful not to do damage to any connections. also look for vacuum lines that may be needing replacing while you are in this location but has nothing to do with present problem.

I really suspect a bad wire somewhere most of all.
There is a connector on the steeriing column under the dash that connects the ignition key switch to the power distribution center and the starter connections.
There are fuses under the dash to the left of the column at times and perhaps in the glovebox or behind it.
 
Hope this helps some and not to confuse you but electrical is lots of work. Just a few tips that may assist you.
Good luck
East Coast Canada Rocks!

2005 chevy classic new lock and keys starts and runs if off more then 10 minutes antitheft comes on and have to wait 10 minutes starts again any idea?


Yeah , take it to a qualified repair shop. You have a anti-theft system problem . Need to have code's pulled
DTC B2947
DTC B2948
DTC B2957
DTC B2958
DTC B2960
DTC B3031
DTC B3033
DTC P1626
DTC P1630
DTC P1631
DTC P1632

This will point to a diagnostic procedure .
The Passlock™ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock™ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.
The components of the Passlock™ System are as follows:
• The ignition lock cylinder and key
• The ignition lock cylinder case, including the Passlock™ sensor
• The ignition switch
• The body control module (BCM)
• The security indicator on the instrument cluster
• The powertrain control module (PCM)

Changing the Passlock™ Components
The following components contain codes or passwords, or must learn codes or passwords for the Passlock™ System to allow the vehicle to start:
• The ignition lock cylinder case
• The body control module (BCM)
• The powertrain control module (PCM)
If any of these parts are replaced, a learn procedure must be performed. Refer to Programming Theft Deterrent System Components . If parts are replaced and a learn procedure is not performed, the engine will crank and will not run or will start and stall immediately.

02 olds alero no start system shut down


Where did you try to by-pass at , with the 2000 ohm resistor ? Is the SECURITY light lit on the instrument cluster ? Probably has another problem other then the key . The anti-theft system in your vehicle can not be by-passed by using a resistor .

The Passlock™ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock™ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.

Your best bet , take it to a qualified repair shop . Before you render it unfixable . (cost to much )

Where is the alarm controll box on the 03 malibu


Alarm box ? You mean anti-theft system ?
The Passlock?"¢ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock?"¢ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.
The components of the Passlock?"¢ System are as follows:
?€¢
The ignition lock cylinder and key


?€¢
The ignition lock cylinder case, including the Passlock?"¢ sensor


?€¢
The ignition switch


?€¢
The body control module (BCM)


?€¢
The security indicator on the instrument cluster


?€¢
The powertrain control module (PCM)


Body Control Module (BCM)
The body control module (BCM) contains the logic of the Theft Deterrent System. The BCM provides the battery positive voltage to operate the Pass lock" sensor. The BCM also measures the voltage of the security sensor signal circuit. The voltage measured will indicate whether the Pass lock sensor has been activated and whether the resistance value from the sensor is a valid value or the tamper value. If voltage measured is in the valid range, the BCM compares this voltage, voltage code, to a previously learned voltage code. If the voltage codes match, the BCM sends a class 2 message containing a password to the powertrain control module (PCM). If the voltage codes do not match, or the voltage is in the tamper range, or there is a circuit fault, the BCM will not send the correct password to the PCM, and the vehicle will not start.
there is nothing you can do , if your vehicle won't start you need to take it to the dealer or a ASE certified repair shop. Messing with the anti-theft system may render your vehicle useless .

Whr is my fuel pump reset button on my 2003 grand am? Its security lock, it wont get any fuel. It cranks but wont start. Not getting any fuel. First time ever happening


There is no reset button.
The problem could be the anti-theft system which would knock out the injectors and spark to the plugs.
If the security light is staying on, the problem could be the chip in the key.

Where is the remote start fuse located?


Do your power door locks work ? There is no fuse for just the remote start !
Remote vehicle start (RVS) begins as an RF message received by the remote control door lock receiver (RCDLR) from a keyless entry transmitter. The RVS request is sent by the RCDLR to the body control module (BCM) via serial data. The BCM monitors system conditions such as content theft deterrent (CTD), hood ajar status, and body DTCs to determine if an RVS even will occur. If conditions are determined to be acceptable, the RVS message is sent to the engine control module (ECM). The ECM monitors system conditions such as engine control parameters and vehicle theft deterrent (VTD) to determine if engine starting will be allowed. If conditions are acceptable, the ECM will initiate engine starting. During the engine run time in a RVS attempt, before the operator enters the vehicle, the ECM may discontinue engine operation if system conditions require it or a message is received from the BCM requesting the engine be turned OFF.
The RVS system will not operate if any of the following conditions are present:
?€¢
A current vehicle DTC that illuminates the malfunction indicator lamp (MIL)


?€¢
The vehicle is in valet mode.


?€¢
More than 2 remote starts have been attempted.


?€¢
The hazard switch is in the ON position.


?€¢
A current hazard switch DTC is set.


?€¢
The vehicle hood is ajar.


?€¢
A current hood ajar DTC is set.


?€¢
The CTD system detects an alarm trigger.


?€¢
Excessive engine RPM


?€¢
Excessive coolant temperature


?€¢
Accelerator pedal position greater than 0 percent


?€¢
Vehicle not in Park


?€¢
Vehicle theft deterrent malfunction


?€¢
A current automatic transmission shift lock control system DRC is set.


?€¢
A vehicle speed sensor signal is detected by the ECM.

Put new key ignition in my 1999 and it will not program to turn over and start the vehicle


Is because the ignition/column and theft module do not match, or maybe damaged theft system during the attempted theft of truck. You can bypass tho.

Car dies when I use my remote start and press the lock or unlock button


This is most likely caused by the car's anti-theft system. Most newer cards require a separate module to be installed to override the anti-theft system while the remote start is in use. Otherwise, when the anti-theft system detects an anomaly, it will immobilize the vehicle.
DEI makes a 556H module for this purpose. The link shows the instrall manual for this device.

No start cranks but does not fire has spark. has fuel if bypassed by relay fuses good new fuel pump a year ago has fuel replaced battery froze, has prostart remote start, been in 8 years no issues 2000...


check to see if the security light or anti theft light flashes. if that is the case, sounds like the bypass for the remote starter may be causeing the no start by tripping the anti theft system. Remove remote starter and bypass system and join any cut wires back together that may be cut for remote starter. Try starting, if theft light still flashes leave key in the on position after attempted start for 15 minutes till theft light goes solid, turn off and try again. Repeat process for three times to re-learn factory theft system in vehicle. If problem still persists, then take to your local dealer to reprogram factory theft module in the cluster.

Vehicle won't start after replacng alternator.


sounds like a bad power connection or dead battery. when you place a load on the system a poor connection or dead battery will allow voltage to drop below norms causing everything to shut down. when you release the key and the load is removed, some voltage returns to power the lights and displays.
