Inspect the connector and harness

you have to check the ecu if you have any codes also see if you have fuel pressure ,try to spray start fluid to see if the car start running

be sure that the communication lines are not in water and must be dry it out or replaced if it corroded

try to start the car from the wire that goes to the starter or see if there is power going to the starter from the fuse box {Sam module}

There could be several reasons why your 2008 C300 won't crank after changing the battery. Here are some troubleshooting steps you can follow to help diagnose the issue: Double-check the battery connections: Ensure that the battery terminals are clean, tight, and correctly connected. The positive terminal should be connected to the positive post, and the negative terminal should be connected to the negative post. Check the battery charge: Even new batteries can be low on charge or faulty. Use a voltmeter to measure the voltage at the battery terminals while the car is off. A fully charged battery should read around 12.6 volts. Inspect the starter and its connections: Locate the starter motor and check its wiring for any loose or corroded connections. If the wiring appears to be in good condition, the starter itself may be faulty. Check the starter relay: If the starter and its connections are in good condition, locate the starter relay in the fuse box and verify that it is functioning properly. You can try swapping it with another relay with the same specifications to see if the problem persists. Examine the ignition switch: The ignition switch might be worn or faulty, preventing the car from cranking. Test the switch using a multimeter to ensure it's functioning correctly. Check the neutral safety switch: If your car has an automatic transmission, the neutral safety switch (or transmission range sensor) prevents the car from cranking unless it is in Park or Neutral. This switch can fail, preventing the car from starting. Try shifting the transmission through its entire range and then back to Park or Neutral to see if the car will crank. Inspect the Engine Control Module (ECM) and immobilizer: If your car is equipped with an immobilizer system or a security system, it could prevent the engine from cranking if there's an issue with the system. Check for any error codes related to the ECM or immobilizer using an OBD-II scanner. If you've gone through these steps and your car still won't crank, it's best to consult a professional mechanic for further diagnosis and repair.

@@BestCarFixes thanks for the reply. Yes I tried doing that the starter cranks but the car won’t start the car never had any water damage or anything like that. I just change the battery to a new model and that’s what happened

@@BestCarFixes the key ignition and the ESL modules all working even the keys they are working. It’s just the car it won’t crank all the fuses relays everything else in good working condition

Hi try to dry out the water and see what happen

On the top of the engine under the hood

it depend

You have to start some where

Thank u. For explaining it like u do. Sum of us don't have men to do it so we have to learn from videos. And you do good at explaining. I thank u

thanks

thank you

I’m not sure if you figured out this problem already seeing as you posted this 12 days ago but the issue you were describing sounds like an ESL problem do you need to get a emulator which bypasses the steering lock in allows the key to function
