what type of engine do you have in your 240 maybe your mass air flow sensor isnt working and youre running too rich
check the battery or battery cables or the alternator or starter
Could be. But it might be an alternator problem instead of a batery problem. You need a good alternator to keep the bttery recharged. I wouldn't run out and buy a battery without getting the alternator checked.
Can be a dead battery, defective starter, loose or corroded battery connection, or blown main fuse. If nothing comes on when you turn on the ignition switch and your interior lights are not working it is not the starter.
So many things could be wrong and cause it to not start, but from what you have provided the next step would be to trace the cables to the starter and see if they are corroded or broken, you didn't mention if the car was turning over or not, so I assume it isnt, so if the battery has power, and the alternator isn't the cause then you need to follow the power, it goes from the battery to the ignition, then to the starter, since we know the battery is good, check to see if power is getting to the starter, if not trace the problem in between those two points.
The first place I'd start would be the battery, alternator and starter. Verify that the battery is good and that the alternator is fully charging it, and that the starter isn't drawing too much current.
When your car isn't starting the car you can't hear it while turning on the ignition. You're gonna have to check the battery and alternator as well before replacing a starter.
The belt turning the alternator which is recharging the battery.
I'm guessing it clicks but won't start? If that's the case its the starter drive going out to engage the flywheel but the starter motor is not turning. Probably needs a starter but you should check to make sure there is correct voltage in system (battery & alternator is o/k) and that the wiring is also o/k to the starter & at the battery.
Spark to cylinder (at random)? If yes... How is the timing?
The starter could be bad. Or the battery. The starter could be bad. Or the battery.
Usually insuffucine power to starter caused by bad or undercharged battery. Try jumping it. You might need a battery or alternator. A bad starter can also do this. Many parts store can test for free and all repair shops can test for you but might charge a few dollars.
I seriously doubt that it's the alternator that's doing the clicking. Most likely it's the starter. Check the battery, a discharged battery can cause that problem. Have the battery charged then start the vehicle and drive it to a shop that can check the charging system. Many auto parts retailers will test the charging system for you.
