Engine wont start it is getting spark and fuel any other reason why it won't start

There could be several reasons why your 2002 Altima won't start even though the engine is turning over. Here are some common causes to consider:

1. Fuel system issues: If the fuel pump, fuel filter, or fuel injectors are not functioning properly, then the engine may not be getting enough fuel to start. You can check the fuel pressure and fuel pump relay to see if they are the issue.
2. Ignition system problems: If the spark plugs, ignition coil, or ignition module are not working correctly, then the engine may not be getting the spark it needs to start. You can check the spark plugs and ignition coil to see if they need to be replaced.
3. Battery issues: If the battery is dead or not providing enough power to start the engine, then the engine may not start. Check the battery voltage and connections to make sure they are in good condition.
4. Starter problems: If the starter motor is not working correctly, then the engine may not start. You can check the starter relay and wiring to see if they are the problem.
5. Mechanical issues: If there are any problems with the engine's timing, compression, or other mechanical issues, then the engine may not start. This would require a more in-depth diagnosis by a mechanic.

It's best to have a professional mechanic inspect your car to determine the root cause of the problem and make any necessary repairs.

... on basic troubleshooting when your boats outboard won't start will help you get ... Outboard won't crank or turn over, electricstart not working ..

do you here the fuel pump working when you turn the key?If not could be a fuse that runs the fuel pump.

spark plugs are deep in the head yet you should get all the the old fuel out first, stale fuel wont ignite and will also clogg fuel filter. you need a mix of atleast 70% new fuel even then its not good for the injecters. If its a manual gearbox a tow start is a quick fix although no go for auto's. cant be much wrong if car was fine when parked, plugs-fuel-filter and possibly fuel pump for sure. If that doesnt fix take plug out put in lead and crank engine to be sure you have spark even just put any plug you know works in lead leaving your plugs in engine just to check for spark y turning over engine looking for spark on plug good spark will be blue but any spark is good.

Won't-start symptoms

Your car may not start for a number of reasons. The following list outlines the most common circumstances and tells you what action you can take to try to remedy each situation:

• The car is silent when you turn the key in the ignition. Check the battery terminal cable connections If they look very corroded, force the point of a screwdriver (with an insulated or wooden handle) between the connector and the terminal post and twist it to lodge it firmly. Then try to start the engine. If it starts, you need to clean or replace your cables.

• The car makes a clicking noise but won't start. This sound usually means a dead battery. If not, check the wiring to and from the starter for a loose connection.

• The car cranks over but won't start. Check the fuel supply to your engine. If that's okay, check whether the electrical spark is getting to your spark plugs.

The engine starts but dies. If your car has a carburetor, check your carburetor adjustment and your choke to see whether the choke is first closing and then opening. If you have fuel injection

Are you getting fuel? if the pump is out then you won't get fuel and it won't start. Check for fuel at the throttle body under the air cleaner also pull a plug and connect it to the wire and ground it to the engine block to see if your getting spark. try this and let me know. I suspect the fuel pump since these last around 8-10 years before they just quit.

There are two reasons a vehicle that cranks well won't start, it is either not getting fuel or not getting fire to the spark plugs. You'll need to determine which and go from there. If no fuel, change the fuel filter or check that the fuel pump is running. There could be a number of reasons if there is no spark but we'll need more info to provide a solution.

There's only two reasons a car won't start if it cranks over okay...no fire to the plugs or no fuel, check to see which it is and go from there.

There's lots of things that can cause your Jeep to not start. Is the starter cranking over? If not, you could have a dead battery, bad battery cables, a bad Transmission Range Sensor, a bad Starter, or a bad ignition switch.

If the starter is turning over but the engine just won't start, you need to figure out what is missing. It either is not getting any fuel or not getting any spark, or something like a timing chain is broken and you have no compression.

You should probably also scan your engine computer. There may be a fault code set that will lead you directly to the problem.

Once you figure out what is missing and/or you have collected fault code(s) I can probably offer more help if you need it.

Hello and welcome to FixYa!

Looks like that there's no current flowing that's why it won't fire up. I strongly suggest that you check and replace the coil pack if necessary. If the coil pack is faulty there will be no current to the plugs. One good reason why it won't fire up.

Hope this helps and thank you for using FixYa! Have a good one!
