SOURCE: dash pannel fuel indicator lamp shows empty but tank full

This would be very common of the fuel pump and level module in the tank. The module from auto zone runs about $280. This must be purchased as a module and replaced. The tank then needs to be dropped out of the car to make this repair. Let me know if you need further instructions to complete this.

SOURCE: My 1995 Cadillac Deville has

The transmission has suffered a big fault - the protection activated so you can't put it in drive and do even more damage. When despite the warning you tried that the defect extended to the engine's ECM which has now gone in protected mode also so the engine has stopped working.
There is nothing you can do, a fault that big can be fixed only at a repair shop - the transmission must be taken out of the car and dismantled to fix it. And i must tell you, it will be very expensive.

Re-adjust the shift linkage to set the lever higher so it is in park when the indicator says it is. Until you do this adjustment on the linkage, the key will be locked in the cylinder. The shifter lever MUST be ALL the way up to park position in order to remove the key.

I have a 1998 cadillac deville concours , the shift indicator light in the dash blinks in park do you have anything on this ?

I have seen this to be a false code before....First make sure trans fluid is at correct level and no leaks..,make sure it shifts correctly while driving...Set park brake,wear safety glasses..Disconnect Negative battery cable for 10 seconds to clear code and reset computer...Reconnect and then test drive...If light stays off it was a false code...It could be a simple problem but save time and money and have it scanned at dealer...

If the fluid level is ok then you need the transmission repaired/rebuilt.

My car reads its in reverse and it wont move to any other gear when the shift lever is moved and it wont start because the indicator shows reverse...

Either you have a broken shifter, cable or possibly the range sensor (also known as the neutral safety switch).

What does it mean when the dashboard reads gear indicator fault, service ride control and change oil soon even after i just got it changed along with service vehicle thats what keeps popping up on my dash...

Off the top of my head the following may be the case for your 1995 Cadillac Deville based on my 1997 Cadillac Deville knowledge:

gear indicator fault- has to do with the shift lever sensor down on the column by the feet,

service ride control- has to do with the air ride shocks in the back or the compressor in the front or the ride control height,

change oil soon- has to do with not resetting the % oil life (just press reset button for a few seconds when the oil % life is displayed)

Hope this helps you out.
