The check engine light ,has to do with ,is the gas cap tight? or the engine is burning RICH and the computer kicks it LEAN and then it kicks back RICH ,then it doesn't know what to do so it puts the check engine light on! it is ok to drive,fuel mileage may be lower. in a lot of cars it has to do with" ignition key cycles" put the key in ,turn it on crank it let it run,turn off ,take key out ,that is one cycle i know with some cars its 20, and some others its 54,your car may have what is called a OBDII .,plug ,under the dash ,a code reader ,could read the code and clear them ,THERE is something else ,that may work with my skyhawk,buick to clear code i could unplug the ---- negative side of the battery and wait 3 minutes and tighten it back on,you'll have to reset your radio

Engine cranks but wont start


Hi there:You will have to pinpoint what the engine is missing...
- Spark
- Fuel
- Compression

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.

Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Toyaota Camry 1994 engine won't start, Engine light on


I would check for fuel,(pressure and injector pulse), spark, and compression, before checking any codes. Lack of any of these basics can result in codes, and then you waste alot of time chasing a symptom, instead of the actual problem.If more people followed basic diagnostics, which always come back to these three basics, rather than chasing codes first,they would find no starts much more quickly.

check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Hi,

Thank you for contacting fixya.com.

Since the spark plug is not coming in contact the engine light is flashing. Otherwise take your car to the nearest auto zone and check if any code is stored in the computer or not to get it fixed. However a flashing engine light means the ECU has detected a misfire strong enough to damage the catalyst in the cat.

Please get back to us if you have further query else please accept the suggestion.

flashing engine light means engine misfire. let car idle and mist the plug wires down with water, rev the engine up and down and look for little sparks jumping from the wires. and arcing wires can cause problems. before changing any bad wires check the coil packs where the wires plug in the three small boxes on the top back of motor. they are three packs with two wires each. one pack at a time take the two wires off to reveal the coil towers. have an assistant start the motor and make sure the spark goes from tower to tower. repeat on remaining two packs. if the spark goes straight down the tower the coil needs replaced. if there is no spark, the coil needs replaced.

Misfire in cylenders 3,6 and 7. service engine light was steady then blinking went back to steady. spark plug problem? did i damage cats?


Possible causes….
•Faulty spark plugs or wires
•Faulty coil (pack)
•Faulty oxygen sensor(s)
•Faulty fuel injector(s)
•Burned exhaust valve
•Faulty catalytic converter(s)
•Stuck/blocked EGR valve / passages
•Faulty camshaft position sensor
•Defective computer

Possible Solutions…
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Random misfires that jump around from one cylinder to another also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

2004 Kia Sedona wont start but i can hear starter.


if the starter is revving very slowly it is the battery, charge battery. if not, It can be three things happing. 1 no spark 2 no fuel 3 no crank signal or the car computer is bad- you will need to unplug one of the spark wires and remove the spark plug and put the spark plug in the spark plug wire boot, and touch the spark plug on any metal on the car and have some start the car. donot touch the spark plug itself and see if there is a spark. if spark is bright, then it is not spark plug and wires but if no or spark is not bright, check the spark plug wires by applying a little bit of water on the spark plug wire and take a 12v test light, connect the clap to ground and and have some one to crank the vehicle, touch allover the spark plug wires with the tip of the test light, if you see spark, replace the wires and change the plugs.. they are not good. if spark is present, check for fuel by removing any one of the spark plugs and see if it is wet. if wet fuel pump is ok but if not go look for the fuel pump fuse and relay. is fuse blown, replace, check the relay resistor with a volt meter. it should be around 40 to 80 ohm. if everything is good from this point check the fuel pump itself by disconnecting the connector to the pump and apply 12v and ground using jumper wires or some wires to the fuel pump if you donot hear the pump,replace pump. if you, the crank signal or computer may be the problem
