Question car won't start

Hi, this is my first time using this so bare with me.

Today I drove my car a couple times throughout the day and after leaving my car sit for just over an hour I went back out to move it. When attempting to start it the car started to sound like it was going to start and then i thought i heard like a "pop" coming from the front of the car. After my car made this sound the car just continued to turn over but cant hear it sound like the engine is going to start.

I don't know if the pop has anything to do with it but just incase i mentioned it. I just changed the spark plugs and wires 2 weeks ago along with air filter. Both the battery and starter are new within the past 6 months.

A friend of mine mentioned to me that it may have to do with a vacum line. If this is the case how might I resolve this problem.

Thankyou in advance for any help that you may be able to give me.

Welcome to the club. It would be really helpful if you included the year and model of your Mercedes.

Also, are you saying that it doesn't start at all anymore, hot or cold?

car wont start

Sorry,

My car is a 1989 300E. 6 cylinders

The car should have still been warm since it only sat for an hour. But would not start then and still will not start.

Was it starting right away (less than a second) before this happened? I don't know what the "pop" would be. Was the engine running fine before? What prompted you to change the plugs and wires? Based on what you've replaced, it looks like it was having starting problems before. What were the symptoms then?

The three basic things you need to start the engine are fuel, ignition, and compression. The ignition is typically the easiest to check first. You've replaced the plugs and wires recently. Make sure that the connectors are seated on the plugs. At any auto parts store you can pickup a spark plug wire tester for under $10. This will tell you if you're getting spark.

Have you taken a look at your distributor cap recently? It's fairly easy to remove. Pop the suppressor cover off and there are three 5mm hex screws that need to be removed. One of them you can't see underneath the cap. I used a universal joint attachment with a 5mm hex bit socket to remove it. It's kind of a tight fit with the fan blade in the way. Also make sure the rotor isn't scorched or damaged. Not knowing much else about what kind of shape your engine is in, the cap and rotor would be the first thing that I would suspect.
