Alternator—A bad alternator can prevent your battery from charging, leaving you with too little power to start your car. Starter: A faulty starter can draw more power than needed, draining your battery. Spark Plugs—Your spark plugs have a lifespan of about 100,000 miles, so problems are rare. If your car is struggling to start, it generally points to an issue with your starter, battery, air filter, or fuel pump. However, your alternator or coolant sensor may be involved—especially if your car runs fine for a while but then starts to struggle again.

Battery condition should be the first test of any no-start diagnosis. Battery condition, including battery voltage during cranking, plays a vital role in starting an engine.Compression and Engine Timing Investigating the engine’s timing and compression can provide clues as to the cause of a crank no start condition. Compression testing measures the engine’s ability to produce pressure within the cylinder and can reveal a blown head gasket, worn piston rings, or bent or broken valves.First, Check the Basics – The very first step to diagnose a “cranks but won’t start” problem is to find if something’s missing – Spark, Fuel and Compression (which includes cam timing).
