@damedolla24 Ok so there are three things that make an engine start: fuel, air (compression), and spark. If one of these isn’t there then the engine won’t turn over. Check for a bad spark plug or a faulty distributor. A way to check the fuel pump is to turn the key to the ACC position and listen for a whirring sound from the back, which lets you know it’s working.
The security light flashing sounds normal. Most cars do this when they’re locked and the anti-theft system is armed.
Also which fans are you talking about? The engine fans or your climate control?
The battery draining within minutes could also be an issue. How old is the battery? If it’s more than 4-5 years old, you probably need to replace it.
Best of luck
