I drive a 2008 Toyota Yaris. I parked the car at home and traveled in August. After a month or so I returned. Somehow water got into the section where we put the plugs so it couldn't start. I called a mechanic who helped me start the car after sucking out the water and burning the plugs and all that. He later said that the car didn't have much compression so he needs to grind the top and change the oil seal between the engine and the gear box since it was dropping oil. To do that he needs to drop the engine. After doing all that, coupling back the engine and mounting it, the car has refused to start till date. A second mechanic tried to start it. After much effort, he and the electrician he brought finally started it but had to go work on the radiator. Coming back the next day, he discovered all four plugs were soaked and the car couldn't start. Pls what could be wrong. It's been over a month now and the car is still not starting.

Sell the car. U see the job I love most in any car doesn't exceed valve stem seals,packing,plugs.but u see that bring engine down..this that. E don be for that car niven. Dem go soon scatter your nozzles. Fuel pump alternator,battery. Better sell it off.

Buy new plug and try a different battery. Trust me it will work

Buy brand new plugs. And pour injector clear inside the fuel tank

Set the car on fire.
It will start by itself and try to flee from the fire.
