Hey guys,
I am new here but need a little help.

I purchased an 2004 c5 from copart and it was listed as running. I went ahead and it put a new battery in it and everything lights up but nothing when I try to turn the key.

I did an internet search and I get mixed opinions. Some say the car wont start with deployed air-bags while others say it will start.

Just hoping someone points me in the right direction.

There's NO reason why it wouldn't start because of the deployment. READ & POST all of the DTCs using the onboard DTCs reading routine!!!!!!

THAT,,,,,,,,,,,,,,, Will tell you why it wont start or tell us where to help you look to solve the issue!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!! Read and post ALL the DTCs and the suffixes H & or C

READING YOUR Engine Diagnostic Codes



The Diagnostic Display Mode is entered with the following procedure:

1) Turn on the ignition but don't start the engine.
NOTE! You can read the DTCs with the engine running and or driving down the road but it can distract you. BE careful! Some DTCs clear themselves when you turn the ignition OFF!
I always read my DTCs prior to turning OFF the ignition switch. If you have any messages on the DIC,, PRESS RESET until they are gone!

2) Press the RESET button to turn off any warning messages. (i.e. door open, trunk open ect.)
3) Press and hold OPTIONS
4) While holding OPTIONS, press FUEL four times within a 10-second period.


Initially, on-board diagnostics go into an Automatic Mode which shows diagnostic codes in a pre-set sequence: PCM - TCS - RTD - BCM - IPC - RADIO - HVAC - LDCM - RDCM - SCM - RFA. All codes will be displayed for each. ( i.e. PCM = 4 codes) If none are present in a given module, you will see No More Codes on the display.
There are two kinds of diagnostic codes, Current and History designated with a letter suffix, "C" or "H". A current C code indicates a malfunction is present and active in the module displaying data. A history code indicates a problem existed sometime in the last 40 or 50 ignition cycles. When not accompanied by a current code of the same number, it's potential evidence of a previous problem, now resolved, that was not removed by clearing the codes.
More likely it's an indication of an intermittent malfunction.
Intermittent codes are the most challenging of the diagnostics. An intermittent code may have happened once, may have happened more than once but is inconsistent or may be happening on a regular basis but not at the time the codes are displayed. History codes can also be caused by a current malfunction in a system that is not operating at the time codes are displayed. An example is the rear window defogger which doesn't operate until the Body Control Module detects engine rpm. For history codes set by a module that does not operate with the key on and engine off, a special diagnostic tool called a Scan Tester is necessary to properly diagnose the malfunction.
Once the system has displayed all modules, it goes into the manual mode which allows selection of each module using combinations of Driver Information Center buttons. Manual mode can also be entered during the automatic sequence by pressing any button except English/Metric (E/M). Once the display shows Manual Diagnostics, select a module by pressing the OPTIONS button to go forward or the TRIP button to go back. Once a module is selected, a code is displayed, and if more than one are present; press GAGES to go forward or FUEL to go back.
To exit the diagnostic mode at any time, press E/M. If you want to erase codes in a given module, press and hold the RESET button To reset the codes once in manual mode, press and hold RESET until it displays NO CODES Press OPTIONS to go to the next module. Repeat the steps until you have reset the codes in all the computer modules.
NOTE!! Only reset the codes IF you want to - it is NOT necessary to do this. Clearing a code does not repair a problem. You are simply erasing the evidence of it in the module's memory. If you clear the code/s, and extinguish the Check Engine Light, your emissions status ready will NOT allow you to pass an emissions test until you have completed the required driving cycles.
Once you have the codes, the next question is: What to do with the information?
First, consult the factory service manual. Any serious C5 Do-It-Yourself owner should invest in the Corvette Service Manual of the appropriate model year. The Service Manual is really a requirement if you want to understand and work on your C5. You can GOOGLE the DTC and also find information on it.




Here is very good site that explains the DTCs:

Make sure to include the H or C suffix!!

Thank you.

I will start there and post some info tomorrow.

I could start the 2008 parts car I have and the steering wheel airbag is deployed. So, the airbag won't be stopping your car from starting.

Holy lot of codes Batman.

So I am thinking I should clear the codes and give it a go and see what code show when I try starting again.

Wanted to post first before doing that. Thanks in advance for the help.

68caddy

I really appreciate the input. Sorry for the delay...family.

The SECURITY light DOES turn off.

Should I attempt to just clear the codes and see if it starts?

Bill Curlee

I ALWAYS clear EVERYTHING and then see what comes back.... TRUST ME,,, If the car isn't happy, what you cleared WILL COME BACK.

Not to be rude or anything, but if it's a three pedal car, you are trying with the clutch pedal depressed?

Hey just wanted to thank those who posted. Cleared codes and it fired up. Whew.

I am sure I will be back with questions.
