2019 Suzuki Swift Pricing and Specs

Your car has an engine Suzuki calls K12C which is a member of the Dual Jet family. That means it does, indeed, have a pair of fuel injectors for each cylinder. It’s conceivable that one set of the injectors is not seating properly or not getting the correct signal to shut off from the computer and that is filling the cylinders with fuel. This may happen until the pressure in the fuel rail dies off, or it could continue dripping all night.

If this is what’s happening, then you shouldn’t attempt to start the car as, should there be enough fuel inside the cylinders, the engine could hydraulically lock, potentially bending con-rods and destroying the entire engine.

How have you diagnosed this as the problem? Have you removed the injectors and had them checked or tested? This sounds like a pretty odd sort of problem for a car as new as this.

The other possibility is that the injectors are getting a computer signal they shouldn’t and leaking as a result. This is a tempting theory as it might also explain why the fan continues to run with the engine switched off. However, it pays to remember that many cars will continue to run their cooling fan after the ignition has been turned off as a way of reducing the temperature of the engine, even though it’s stopped. This should have no effect on the injectors, though.

The price will depend on the year and variant. It will aso depend on if you go to a dealer or not. You can read more about how to replace your keys here.
