Hi, is there anyone out there who can help me?

I have a 2004 C5 Convertible Corvette that has had the battery replaced. After the battery was replaced it started and ran for about a day, now it will not start at all! when i turn the ignition on all the dials go from rest position to max out then back to rest position again, every fault appears on the dash readout like.... REDUCED ENGINE POWER, SHOCKS INOPERATIVE, CHECK TYRE PRESSURE, SERVICE VEHICLE SOON, LOW FUEL. also the fuel gauge shows empty even though the tank contains about 30 Euros of fuel, the car will fire and run for a nano second then cut out.
Does anyone out there know what could cause this? any help would be largely appreciated

4) While holding "OPTIONS", press "FUEL" four times within a 10-second period.

nothing happens at all, the car dash just keeps showing me these messages.......

REDUCED ENGINE POWER, SHOCKS INOPERATIVE, CHECK TYRE PRESSURE, SERVICE VEHICLE SOON, LOW FUEL.

if i try and start the car it will start and it will even rev, but the engine will only stay "alive" for 1 second. Im thinking that maybe the immobiliser in the alarm may be faulty...? but this still dont explain the messages on the dash and the reason why i cannot enter the diagnostic mode... any ideas?
You need to get those codes out of there... A couple of tips. (you are probably already doing this, but I just want to clarify in case)[QUOTE/]

1) Turn on the ignition but don't start the engine. Make sure your ignition is in the ON position, not the ACC position

2) Press the "RESET" button to turn off any warning messages This means clear ALL messages including door ajar, hatch ajar, etc. Your dic should be completely blank when you start your next step. This doesn't mean press and hold the reset button, you'll have to press the reset button one time for each message displaying on the dic screen. Keep pressing the reset button until no messages appear.

3) Press and hold "OPTIONS"

4) While holding "OPTIONS", press "FUEL" four times within a 10-second period. It should be buttons 1 and 4. Hold down 4 and press 1 four times within... try less than ten seconds. I don't know what the time limit is, I always do it really fast.

After you get in there, press one of the top four buttons to enter manual diagnostics mode. Use buttons 3 and 4 to scroll between the different electrical systems in the vehicle and buttons 1 and 2 to scroll between the individual codes within a system.

If I were you, I'd clear ALL of the codes the first time you get in there. Then turn the car off for a minute then start it and let the engine die again. Then pull the codes. This will ensure that you are only chasing codes that are problems as of NOW, not codes that have been in there for a while and just never cleared. After you get the second set of codes out, post them here and we'll try to give you a hand.

Also, where are you located? You should fill out your profile when you get a second... Pulling codes doesn't take long, if there's someone close to you they might come by and show you how to do it.

EDIT

There's another member experiencing a problem very similar to yours and a there a couple of VERY knowledgeable and helpful members that seem to think he might have lost communications with the PCM. Here's the thread: http://forums.corvetteforum.com/c5-t...rt-at-all.html

Try again to get the codes out, but if you can't, I would investigate from this angle...

Good luck!
