Hello there. The car full randomly struggles to start sometimes. It doesn’t depend on weather or how much I drive it before. It can start every time after the struggle, so I don’t have to try it twice, but it is concerning. What can it be? Does anybody have problems like this?
Possible issues could be: glow plugs need to be replaced, leaks in the fuel lines, a faulty coolant temp sensor, or a stuck EGR valve.
Slow crank speed? If that’s the case, check the cable from the alternator to the starter and to terminal 30 in the plenum chamber.
I read somewhere that if the starter is completely gone, it might not even crank at all. Just something to keep in mind.
I’ve dealt with similar issues before. Sometimes it helps to clean the battery terminals. Corrosion can cause starting problems too.
If you can, consider getting a diagnostic tool to read any error codes. Might save you some time figuring this out.
