What do you do if your car wont start but it’s not the battery?

Try: Cycling the Key If your car turns on but won’t start, turn on the dome light and watch it while you try to start the engine. If the light goes out, it’s a sign the battery is really weak—almost dead. To heat up the battery, terminals and starter, try the “key cycling” trick.

What happens when the oil pressure sensor goes bad?

The Oil Pressure Light is on If the Low Oil Light comes on, but you check the oil in the engine and it’s at a good level, then a faulty oil pressure sensor may be to blame. When this sensor goes bad, it will start to give inaccurate readings. After the readings fall out of specification, a warning light is set.

What sensors can cause a car not to start?

A bad Crankshaft Position sensor is a common cause of no starts. The signal from this sensor goes to the PCM or ignition module that switches the ignition coil(s) on and off. If you have an RPM signal, a bad ignition module or PCM may not be switching the coil(s) on and off.
