What would cause engine to turn over and not fire or cut out while driving?

Engine turns over but won't fire:

1. Lack of fuel: This could be due to a faulty fuel pump, clogged fuel filter, or a problem with the fuel injection system.

2. No spark: This could be caused by a faulty ignition coil, spark plugs, or wiring problem.

3. Incorrect engine timing: This could be due to a slipped timing belt or chain, or a faulty timing sensor.

4. Bad compression: This could be caused by worn piston rings, damaged cylinder walls, or a faulty head gasket.

Engine cuts out while driving:

1. Fuel system problems: A clogged fuel filter, faulty fuel pump, or injector issues can cause the engine to run out of fuel while driving.

2. Ignition system problems: A faulty ignition coil, spark plugs, or wiring issues can cause the engine to lose spark while driving.

3. Air intake problems: A blocked air filter or damaged air intake system can prevent the engine from getting the air it needs to run properly.

4. Exhaust system problems: A clogged catalytic converter or damaged exhaust system can cause the engine to overheat and cut out.

5. Electrical problems: A loose or corroded wiring connection, faulty sensor, or problem with the engine control unit (ECU) can cause the engine to cut out while driving.
