Heres the deal. When you put a remote starter on this year Cadillac (and about 100 other GM models) you have to bypass the security system. On these vehicles, that chip in your key has to communicate with the ignition/lock cylinder and then the TDM (computer) to allow your starter to start and/or allow the injectors to continue working. So what people will do is "bypass" the key and lock cylinder to fake the TDM into believing it has the correct key chip inserted. This allows you to remotely start a vehicle with an antitheft. My guess is that your TDM has now failed. Since the remote starter (which is hooked directly to starter) works and the key doesnt AND we already know that the system has been altered.... I'd put money on the TDM (theft deterrant module). Check out this link. You'll find an answer to your problem for sure. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Sometimes the security system can shut off your starter. Other times, a new starter does not match up with the correct frequency of the security system and can cause a starter failure. Read up on this site. Check to see if the security light is on. http://vatspasslockpasskeysecurityhelp.yolasite.com/

check fan fuse,fan relay and power at fan connector most likely bad relay.

Assuming you refilled on gas it is possible that in running so low on gas the concentration of containments have clogged the sock of your fuel pump. Should this be the case you will need to change the fuel pump.

yes, you can use regular gas but it wont perform as well. Long term use of a lower octane fuel can lead to other problems down the line but this is not a critical issue.

It could be many things. I would start by checking the coolant level and topping it off. If it is fine, I would then look for leaks and maybe look at the oil to make sure there is no mixing of oil and coolant which would indicate headgasket or a crack in the motor. If no leaks, you may want to then check the thermostat. If it is fine, the next step would be to test the fans to see if they are operational.
If you get that far and don't find anything, I would recommend sending it to a technician because it may be something difficult to diagnose. Goodluck.

check wiring or ground to driver side sockets.

You have to disconnect the battery in order for the compressor to come on so it will take in freon. The compressor is controlled by the computer so disconnect the battery to reset the computer than try putting in freon. hope this helps leave comment.

Don't take it to a dealership. They charge for things that should be free and charge triple for everything else. Just take it to a reliable repair shop.

Here is a great write-up to completely bypass the VATS system. This was the only thing that saved my car. http://newrockies.ca/vatsbypass

The problem is with the spark plug or in the starter . Otherwise the area you are living in may be causing this problem as the engine gets damaged during start up.

Here the bulletin explaining how to replace headlights. At the end of the document is explained how to align the headlight. Read the part titled Aiming The Headlights. The document should cover your model.

Below also the user manual in PDF. No info on headlight aiming is contained in the manual. Please refer to the service bulletin posted above.

Wiring diagram for the front components of the suspension:

As you can see both the solenoids are wired seperately to the control unit. I think the problem would be in the wiring. You should get 0V at the suspension with the ignition off. Disconnect the harnesses at both wheels and measure the resistance on the solenoids. The readings should be within 10% of each other. Then disconnect the harness at the control unit and check each of the wires for:
  • Continuity
  • Short to battery voltage
  • Short to earth
and repair where nescesary.
If you still have not found the problem I'd suggest using a set of leads, connect RF sensor to LF harness and vise versa. Then check to see if the code reader brings up LF wheel instead of RF wheel. If it does replace the strut - again!! If not your problem is wiring or control unit.

Hello mrsalbert, my name is JShreader. Thank you for choosing fixya.com

Depending on which oxygen sensor you are looking for...there are several of them throughout the Exhaust System. I will start out by giving you a brief description of what and oxygen sensor is, and they're general purpose.

Four Heated Oxygen Sensors (HO2S) are mounted in the exhaust system where they monitor the oxygen content in the exhaust stream. There is an oxygen sensor mounted in each exhaust manifold and one on each end of the catalytic converter. the oxygen sensor located in the front exhaust manifold is the Bank 2 Sensor 1 (Front) sensor. The oxygen sensor located in the rear exhaust manifold is the Bank 1 Sensor 1 (Rear) sensor. The oxygen sensor located in the Y-pipe ahead of the catalytic converter is the Bank 1 Sensor 2 (Pre-converter) sensor. The oxygen sensor located in the catalytic converter outlet is the Bank 1 Sensor 3 (Post-converter) sensor.

An oxygen sensor acts like a battery because it creates its own signal voltage once it reaches operating temperature. This voltage is produced when the oxygen content in the exhaust stream is different than the oxygen content in the atmosphere. A lean condition (high oxygen content in exhaust) will produce a low voltage (near 0 volts) and a rich condition (low oxygen content in exhaust) will produce a high voltage (near one volt). The PCM provides a reference signal voltage (0.45 volt) and a ground to the sensor. The PCM reference voltage is necessary because the oxygen sensors do not provide their own voltage until they reach operating temperature.

the oxygen sensors also incorporate a heating element inside of the sensor housing. This heating element is energized with the ignition On and allows the sensors to reach operating temperatures quickly. The PCM can then use oxygen sensor information sooner after engine start-up.

The PCM uses oxygen sensor information during Closed Loop operation to constantly adjust fuel control to reduce exhaust emissions. Because the oxygen sensors provide information sooner after engine start-up, exhaust emissions are reduced. Faulty oxygen sensors will cause various driveability conditions and will set a DTC.

That being said...I uploaded a .pdf for you of pictures showing the locations of ALL the oxygen Sensors on your Vehicle. You can download it by clicking HERE.

I hope this helps you. If you have any more questions or need any more diagrams, please don't hesitate to ask...Thanks again, JShreader!

Your engine condition could be caused by many factors, and is difficult to pin point without knowing if there are any PCM trouble codes stored in memory. If the check engine light lites up, I am sure you would have a coded stored in memory, and would be the first place a I or a Technician would check before proceeding with diagnostic procedures. With this being said, When was the last time spark plugs or other maintenance was performed on this vehicle? How many miles are on the vehicle?

Hello, Code 1406 refers to the EGR Valve pintle position, If the wiring and connector is okay then you will need a new EGR Valve, It is located on side of engine on top near the fuel lines attached with two bolts has one electrical connector

Check your battery cables for corrosion, make sure they are tight, check the ground wire (black wire) from the battery to the engine, make sure it is clean and tight. Use battery terminal cleaner to clean cables (do get any on top o the battery) If cables are bad corroded, replace the bolts on the cable and make sure the battery connectors are clean, Have you tried a jump start? It may be a bad battery. If the lights con
me on that does'nt mean the battery is good.

Please check if the rectifier/regulator unit has failed or is weak.
This can create fault in the charging system and cause fault in the ignition.Check the battery ground , clean terminals.
So check this out and check the timing ofthe engine.
