What to do when the car P light keeps flashing and won't start?

First, it may be an electrical or electronic malfunction. Electronic malfunction mainly refers to the central computer control board losing its function. Then it could be a fuel system failure, or the battery has failed. Finally, it may also be a mechanical failure, as the car's self-diagnosis system constantly monitors the vehicle's operation.
When my car won't start and the P indicator keeps flashing, I first check if the anti-theft system is locked. Some models won't start if they don't detect the correct key signal, and the indicator will flash. The last time I encountered this situation, it was caused by a depleted key battery, and replacing it with a new CR2032 battery solved the problem. Next, I check the car's main battery: use a voltmeter to measure it—if it's below 12 volts, it might be dead, and a simple jump-start can get it running. I also confirm whether the transmission is in the P position, as occasionally forgetting to shift gears can cause a stall. If none of these steps work, it might be a blown fuse or a deeper electrical issue requiring professional repair. As a habit, I always have the technician check the electrical connections during routine maintenance, which significantly reduces such problems.
My car often has trouble starting, with warning lights flashing, especially when I'm taking the kids out. My first thought is safety: immediately push the car to a safe spot on the roadside and turn on the hazard lights. Check if the key is in the detection zone—modern cars have strict anti-theft systems, and the wrong key position will trigger a light. Try restarting or using a spare key. Battery issues are the most common; I’ll use a portable power bank to jump-start it, and if that doesn’t work, call for roadside assistance. Afterward, I take the car for a full electrical inspection, including the anti-theft module settings. Prevention is simple: check the battery connections monthly to ensure they’re clean.
After driving for many years, I've encountered the situation where the P light flashes and the car won't start several times. Usually, it's not a big deal, with weak key battery or anti-theft activation being the main causes. I immediately replace the battery in the remote key, which mostly solves the problem. If that doesn't work, check if the transmission is in the P position and if the brake pedal is functioning normally. For battery issues, a jump start usually does the trick. Remember to regularly maintain the electrical system to prevent electrical problems from accumulating.
