To start a car after replacing the radiator when it’s struggling, check to see that the battery is charged. It might be a drained battery problem. Otherwise, look for an issue with the fuel or ignition.
The simplest explanation is that the battery was drained while the repairs were completed. Charge it up, double-check the connections, and try again.
If you’ve checked all the connections—and your car is cranking—but nothing is happening, it may be an issue with fuel delivery or spark production. Check the fuel filter and fuel line for blockages, and assess the fuel pump for functionality. If there’s no spark, then you may have a faulty coil or igniter.
If the car doesn’t crank, you should look at the fuses and ECU for problems.
