Difficult commencement in the frigid morning.

[Gorrillaas]

Greetings, I want counsel from everyone. The 2013 Kia Ceed 1.4 Diesel has difficulty starting on chilly mornings. Installed a new battery, replaced glow plugs, performed servicing, cleaned the fuel tank filter, and cleaned the swirl flaps. Currently, one glow plug is malfunctioning and lodged in the cylinder head; nonetheless, an expert has advised that its absence would not significantly impact performance, since three functioning plugs should enough for ignition. This morning, it was rather difficult to begin due to an outdoor temperature of around 6 degrees. Any suggestions or others experiencing similar situations would be appreciated for any assistance.

Several intriguing subjects

The first task I will address is replacing the gasoline filter to see if it resolves the issue. If that does not resolve the issue, I would then contemplate extracting the lodged glow plug - it will be removable! The mileage has not been specified, however it may be prudent to invest in a complete replacement.

Most competent diesel professionals would promptly identify and resolve the starting issue. If you hesitate to risk injuring the component while trying to extract the seized glow plug, let a professional to do it.

Wishing you success in your endeavours.

Attempt to prime the gasoline filter before to ignition by pressing the button located atop the filter housing. If the automobile starts properly, it indicates a potential fuel loss that requires investigation

There are 230,000,000. Serviced every 10,000 miles and had a comprehensive service 4,000 miles ago. The filter in the tank was immaculate; I was really astonished by its cleanliness, therefore I do not believe that contaminated gasoline is the issue. The glow plugs have just been replaced, with three new ones installed. However, the second glow plug is spinning and nonfunctional upon testing. I consulted an expert about its removal, and he assured me he could remove it without issue, but he said with certainty that it would not resolve my problem, as the engine would operate on three cylinders without difficulty. Attempted to prime the gasoline system using the filter primer pump; nevertheless, it was difficult, resulting in no loss of pressure.

Clean the Mass Air Flow sensor.
The engine temperature sensor may be indicating to the ECU that the engine is warm, which is a prevalent issue in Volkswagen vehicles that complicates cold starts. While the impact may be less severe in diesel engines, it remains a potential reason.
Perhaps the crankshaft sensor, etc.

I have been doing fault analysis and see 12.4 volts at the wire attached to the glow plug rail; however, there is no voltage present at the rail itself. The wire is effectively crimped to the rail, leading me to assume that the rail should be energised; yet, I am receiving no voltage reading from the rail. The relay is providing electricity, indicating that it is functioning properly.

The glow plugs will also heat up if functioning properly.
