cts wont start no check engine light
Country: United StatesMake: CadillacModel: CTSEngine: 3.6
ran CabIBD2 diagnostics flashing C EV O and OH
I don't know what CabIBD2 is, nor do I know what the letter codes mean.What year is that, and what can you tell me about the tool you're using/those letter codes?
sorry it is a 2005 CTS 3.6 engine codes from the On board diagnotsic tool
I'm not familiar with that diagnostic tool, nor those codes. I assume they mean something, perhaps your owner's manual for the tool has that information.At any rate, have you gone through and checked all of the fuses yet? It sounds like you have no power.There is also a recall campaign for this car for a no start concern, that has to do with some faulty ECM software.... this may be a part of your problem if this hasn't been corrected in the past. I'll attach that campaign notice here:

Cadillac vehicles will also display the message, "Starting Disabled, Remove Key" on the Driver Information Center. All vehicles will set a Diagnostic Test Code (DTC) of P1631 when the condition occurs.
Dealers are to reflash all affected 2004-2005 vehicles with corrected software/calibration. The memory location that was susceptible to damage will no longer be used.

Dear General Motors Customer:

We have learned that your vehicle has an Engine Control Module (ECM) programming error, which can cause ECM memory damage and result in the inability to start the engine. Cadillac vehicles will also display the message, "Starting Disabled, Remove Key" on the Driver Information Center.
To prevent this condition from occurring, your General Motors dealer will reprogram the Engine Control Module (ECM). This service will be performed for you at no charge.
Otherwise..... is it cranking, or not cranking? Any other messages on the dash?
this is the third time this has happened.first time dealer said it was a battery and the computer had to be reprogrammedsecond time dealer said it was a bad fuel pumpit cranks, i believe it is getting gas but no fire
this is the third time this has happened.first time dealer said it was a battery and the computer had to be reprogrammedsecond time dealer said it was a bad fuel pumpit cranks, i believe it is getting gas but no fire and yes fuses checked good.
This is something that I would have a Tech 2 attached to, for sure. I don't know what your code reader is telling us, that information isn't related to OEM type data at all. But having checked basics like fuses, etc. I'd say that this definitely needs a GM or other high end scan tool to test communication with the PCM, and to read data lists to see if there is cranking RPM, whether fuel is disabled due to theft, etc etc. What you have is probably beyond the capability of a DIY repair, at this point. It needs expensive tools and expertise, particularly if this is the third time out.
