Doesn't start any suggestions

I pulled my intake manifold and it was full of oil

It started with the engine temp gauge saying hot. engine was not hot. gauge still stuck there, now gas gauge stuck on full.
speedometer not accurate will stay on 49 for a long time even if going faster. Any ideas what is wrong?

Help help SOS!!!!! SECURITY SHUT DOWN ALL FUEL SUPPLY HOW DO I FIX IT 2001 Cadillac deville DTS!!!!

Replaced a senor dash show hot car shuts down

It had been working on and off, sometimes the seat would move, other times it wouldn't. Seat moves forward and backwards and shoulder strap adjuster moves up and down. Someone told me to cycle it through a full recline a couple of times to "straighten out the threads". Now it won't come up at all and is in full recline. Got code B1815 - driver recline forward switch CKT malf. Is there a way to bypass the power controls and get it up manually?

The air conditioner ot working and I can't see the gauge

while driving down highway engine started bucking and when checked, the tranny pan was dry. new synthetic was added but won't go into drive.

Fuel pump will run at all times even with key off. Security light on dash will also illuminate when key is in the on position.

took it to the caddy dealership and to fix this is around 1100 dollars.

abs brake and traction control light are always on garage wants to charge 3000 dollars is this expensive ? also cold air does not come to the back only to front vents back vents get hot air when front air is on
