Engine Starting Problems Gasoline Engines Engine turns over, but will not start

  1. Check fuel level in fuel tank, add fuel if empty.
  2. Check BATTERY condition and state of charge. If voltage and load test below specification, charge or replace battery.
  3. Check battery terminal and cable condition and tightness. Clean terminals and replace damaged, worn or corroded cables.
  4. Check FUEL DELIVERY SYSTEM. If fuel is not reaching the fuel injectors, check for a loose electrical connector or defective fuse, relay or fuel pump and replace as necessary.
  5. Engine may have excessive wear or mechanical damage such as low CYLINDER CRANKING PRESSURE, a broken camshaft drive system, insufficient valve clearance or bent valves.
  6. Check for fuel contamination such as water in the fuel. During winter months, the water may freeze and cause a fuel restriction. Adding a fuel additive may help, however the fuel system may require draining and purging with fresh fuel.
  7. Check for IGNITION SYSTEM failure. Check for loose or shorted wires or damaged ignition system components. Check the SPARK PLUGS for excessive wear or incorrect electrode gap. If the problem is worse in wet weather, check for shorts between the spark plugs and the IGNITION COILS .
  8. Check the engine management system for a failed SENSOR or control module.
Engine does not turn over when attempting to start
  1. Check the battery state of charge and condition. If the dash lights are not visible or very dim when turning the ignition key on, the battery has either failed internally or discharged, the battery cables are loose, excessively corroded or damaged, or the alternator has failed or internally shorted, discharging the battery. Charge or replace the battery, clean or replace the battery cables, and check the alternator output.
  2. Check the operation of the neutral safety switch. On automatic transmission vehicles, try starting the vehicle in both Park and Neutral. On manual transmission vehicles, depress the clutch pedal and attempt to start. On some vehicles, these switches can be adjusted. Make sure the switches or wire connectors are not loose or damaged. Replace or adjust the switches as necessary.
  3. Check the starter motor, starter solenoid or relay, and starter motor cables and wires. Check the ground from the engine to the chassis. Make sure the wires are not loose, damaged, or corroded. If battery voltage is present at the starter relay, try using a remote starter to start the vehicle for test purposes only. Replace any damaged or corroded cables, in addition to replacing any failed components.
  4. Check the engine for seizure. If the engine has not been started for a long period of time, internal parts such as the rings may have rusted to the cylinder walls. The engine may have suffered internal damage, or could be hydro-locked from ingesting water. Remove the spark plugs and carefully attempt to rotate the engine using a suitable breaker bar and socket on the crankshaft pulley. If the engine is resistant to moving, or moves slightly and then binds, do not force the engine any further before determining the problem.



Engine stalls immediately when started

  1. Check the ignition switch condition and operation. The electrical contacts in the run position may be worn or damaged. Try restarting the engine with all electrical accessories in the off position. Sometimes turning the key on an off will help in emergency situations, however once the switch has shown signs of failure, it should be replaced as soon as possible.
  2. Check for loose, corroded, damaged or shorted wires for the ignition system and repair or replace.
  3. Check for manifold vacuum leaks or vacuum hose leakage and repair or replace parts as necessary.
  4. Measure the fuel pump delivery volume and pressure. Low fuel pump pressure can also be noticed as a lack of power when accelerating. Make sure the fuel pump lines are not restricted. The fuel pump output is not adjustable and requires fuel pump replacement to repair.
  5. Check the engine fuel and ignition management system. Inspect the sensor wiring and electrical connectors. A dirty, loose or damaged sensor or control module wire can simulate a failed component.
  6. Check the exhaust system for internal restrictions.
Starter motor spins, but does not engage
  1. Check the starter motor for a seized or binding pinion gear.
  2. Remove the flywheel inspection plate and check for a damaged ring gear.
Engine is difficult to start when cold
  1. Check the battery condition, battery state of charge and starter motor current draw. Replace the battery if marginal and the starter motor if the current draw is beyond specification.
  2. Check the battery cable condition. Clean the battery terminals and replace corroded or damaged cables.
  3. Check the fuel system for proper operation. A fuel pump with insufficient fuel pressure or clogged injectors should be replaced.
  4. Check the engine's tune-up status. Note the tune-up specifications and check for items such as severely worn spark plugs; adjust or replace as needed. On vehicles with manually adjusted valve clearances, check for tight valves and adjust to specification.
  5. Check for a failed coolant temperature sensor, and replace if out of specification.
  6. heck the operation of the engine management systems for fuel and ignition; repair or replace failed components as necessary.
Engine is difficult to start when hot
  1. Check the air filter and air intake system. Replace the air filter if it is dirty or contaminated. Check the fresh air intake system for restrictions or blockage.
  2. Check for loose or deteriorated engine grounds and clean, tighten or replace as needed.
  3. Check for needed maintenance. Inspect tune-up and service related items such as spark plugs and engine oil condition, and check the operation of the engine fuel and ignition management system.

Hot and Cold When your Engine is Hard to Start
In order to surpass this problem and to prevent it as much as possible, learn how to solve it by knowing why it happens.

When a hot engine is hard to start, most of the causes are fuel related problems. Fuel cannot circulate well due to the way in which vapor blocks it. As a result, the engine would not start as easily as it should. In worse cases, it would not start at all. This happens if the engine is extremely hot.

Until after a while the engine was shut off, it would keep on acquiring temperature. The biggest amount of water vapor would be spreading around during this process. It therefore means that during this period, there are higher chances of its obstruction to the engine. So when you are driving in hot weather and you have just turned off the car and you experience difficulty in stating the engine, do not panic. Just wait for a couple of minutes and then start it back.

Because the fuel remains inside the injectors by being under a very intense pressure, engines that are fuel injected do not experience and suffer this problem as much as others do. In this case, fuel injected engines would not become so easily moved by vapors as compared to other engines. From this fact, it can be further deduced that auto mobiles may have different problems in starting their engines.

Another reason of a difficulty in starting a vehicle is the coinciding of the engine's hot temperature to a hot season like the summer. In this scenario, refiners alter from a fuel blend to another. Due to the process where in hot weather causes fuel to evaporate faster, gasoline refiners sometimes alter from a higher hot blooded fuel to a lower one when summer approaches. The fuel could evaporate too much that it would create too much vapor and would eventually inflict the engine. This instance happens when refiners alter back to a higher hot blooded fuel while the engine is still exposed to high temperatures of the summer season.

Now you know why hot engines are hard to start and what to do with it. What about if a cold engine is hard to start?

Difficulty in starting a cold engine is really a problem especially to those living in cold areas. This is experienced due to several reasons, and one of which can be based on the cold effect on liquids evaporation. Less gasoline is evaporated when the engine is cold. This causes the fuel to be more burdensome to burn due to the fact that it is burnt when it is evaporated.

Oil becomes much thicker in cold areas than in hot ones. This is another reason why cold engines are hard to start. Like any other fluids, oil alters its characteristics when it is heated or when it is in a very hot weather. Often times, this causes the oil to have problems at the time it circulates in the engine of the vehicle.

Other car parts that contribute to this problem are the batteries. Under a cold weather, the car batteries sometimes experience problems that consequently affect the engine of the car. When being cold, batteries loose their agility. This is because they do their jobs due to chemical reactions. And when they loose their agility, of course it means that they do not function well. Under these circumstances, the energy of the car is affected and so the engine start is also affected.

Another problem could be the air intake. Like in the case of your Dodge car, the Dodge cold air intake, it might not be functioning well that affects the performance of your engine.

If these problems happen together at the same time, they imply a huge problem in starting the engine.

Spray ether into the engine. Use one that would evaporate quickly and help the engine start. Do this to overcome the problem on the lack of gasoline evaporation. Aside from this, you can also use thin synthetic oils in order to prevent very thick oil that would not circulate well. You if can maintain the car from being isolated from cold, better!

The engines run very lean for fuel efficiency. Although a "cold start sequence" gives the impression of freezing temperatures, the operating range is much higher. The water temperature sensor (some have 2) may be staying too warm for the reset. You may need to change the sensor. Then the fuel mix will be richer and the engine will start.

just purchased a diesel truck please dont laugh just dont know why are their two batterys under hood what is the reason for this


Diesel engines utilize a compression ratio about 2 and1/2 times higher that a gasoline engine. This means it takes much more power from the starter to crank it over. Two batteries are necessary to power the oversized starter required to turn a diesel engine over. Also, many diesel engines use glow plugs to warm up the combustion chamber to aid cold starting. The extra battery provides power reserve for this function also.

Can you spray ether in the throttle body to assist in engine ignition ?


No, do not spray anything in the throttle body. If the unit is not starting correctly, fix THAT issue. You do not specify anything about your vehicle and model, so little help can be offered. BUT, Gas or diesel, you should not have to spray anything to help in starting, something else is wrong, find and fix that.
