The 2007 Cadillac DTS does not have an inertia fuel reset switch. Instead, it has a fuel pump relay located in the rear fuse block under the back seat. If you are experiencing a fuel system issue, you may want to check the fuel pump relay and fuse first.

Here's a wiring guide for the fuel pump on a 2000 Cadillac Deville: 1. Remove the fuel tank and access the fuel pump module. 2. Disconnect the electrical connector from the top of the fuel pump module. 3. Locate the wiring harness that runs from the fuel pump module to the car's electrical system. 4. Cut the wires on the old fuel pump module connector, leaving enough wire to splice the new connector onto. 5. Connect the black wire from the new fuel pump module connector to the black wire in the car's wiring harness. 6. Connect the purple wire from the new fuel pump module connector to the purple wire in the car's wiring harness. 7. Connect the gray wire from the new fuel pump module connector to the gray wire in the car's wiring harness. 8. Connect the black/white wire from the new fuel pump module connector to the black/white wire in the car's wiring harness. 9. Connect the new fuel pump module electrical connector to the car's wiring harness connector. 10. Reinstall the fuel tank. Note that it is important to follow the wiring guide carefully to ensure proper installation and avoid damaging the fuel pump or electrical system.

If your 2005 Cadillac STS is displaying "TheftLock" on the navigation and radio screen after replacing the battery, it means that the anti-theft system has been activated. Here are the steps you can take to unlock the system: 1. Turn the ignition key to the "On" position. Don't start the car, just turn the key to "On" position. 2. Wait for the "TheftLock" message to disappear from the navigation and radio screen. This may take up to 10 minutes. 3. Press and hold the "1" and "4" buttons on the radio simultaneously for several seconds until "000" appears on the screen. 4. Use the "TUNE" knob to enter the code that was provided with the vehicle's owner's manual. If you don't have the code, you will need to contact a Cadillac dealership or a certified mechanic to retrieve it for you. 5. Once you entered the correct code, press the "AM/FM" button to unlock the radio and navigation system. If all doesn't work, it's time to contact a Cadillac dealership or a certified mechanic to help you sort it out.

Hi Joan Whittaker,what does no crank mean. the starter motor is dead? some posters call d crank= running engine. which engine there? cranks fast but will not start. underhood fuse box f24 blown? step 2 after all fuses checked is: shift to Neutral see if that allows cranking per my red circle below is PCM control. is the dash IMMO lamp happy? as you can see the pcm decides to do the cranking or not via its starter relay. if you scanned the PCM it will tell you why it id not start. immo error OR A/t PRNDL (TRS) ERRORS. OOPS the IMMO page in your users guide covers IMMO if key 1 fails try key2, car came with 2 keys new. READ ALL PAGES ON IMMO FIRST If the engine does not start and the Security System Light comes on Security System Light (CLUSTER LAMP ICON LOOKS LIKE CAR CUT IN HALF WITH A PADLOCK, never ignore this lamp. This light flashes when the Theft Deterrent System has been activated. https://www.manualslib.com/manual/1078925/Cadillac-Cts.html?page=256

the word sensor , missing? all cars in USA 1996 up for sure have CKP sensor and 99%^ of them changed out is not cure. not scanning the PCM first is why you miss out on causes the crank sensor is in 3 places all front ,middle or rear of the crank shaft. the 3.6 L the tone wheel is on the REAR service manual shows at #8

OP you did that all wrong. the parts are NOT PNP not plug and play at all and even by LAW. those parts must be reprogrammed and remarried or IMMO will be dead.

If you can unplug the module and the draw goes away, replace the module.

I would look for a vacuum leak.

There are two easy tests for the catalytic converters. One, use a infrared pyrometer and measure the temperature of both catalytic converters and compair the readings. There should not be much difference between the two if both are flowing correctly. Another easy test is to drill a 1/4" hole before each cat and check for excessive back pressure.
