If the vehicle sit for a period of time, even over night and it won't start with the new battery and alternator, you have a dead short drawing voltage from the battery until it goes dead. Disconnect the positive terminal from the battery and connect a test light to the cable and touch the battery positive post with the other end of the tester. If the tester lights up, you have a draw on the battery causing it to go dead. Now you need to pull 1 fuse at a time while the tester is connected to see when the light goes out. When it dies, that is the circuit that needs to be traced to find the faulty switch, bard wire or whatever is the cause. Good luck.
First thing to do is check the transmission fluid level and check for leaks. If the transmission is very low on fluid, for example a cooler line broke, it would cause this situation due to no pressure. If you do not see any outside leaks, but transmission fluid is very low, check your radiator overflow tank, if it is overfull and milky, this would mean the Trans cooler that goes through the radiator is leaking fluid into the coolant system.
plug in the OBD II scanner device into port , also an oscilloscope works too but nowadays not many shops got one one of those , the scanner is the easiest way
If it is a 4 cylinder, then you will see spark plug wires that connect to the top of the engine, under each wire there is a spark plug. These wires are fairly thick, they are around 1/4 inch diameter. You need to be careful pulling them off the engine so you don't leave behind the boot. If you haven't replaced plugs before, it is a little tricky, so good luck.
i added the comment if it's a 4 cylinder or V6 engine (v6 is harder to do because the back 3 plugs are a pain)
if you got a 4 cylinder engine, here's a video!
it's for a 2009, but you have the same setup ~ coil over sparkplug system
PS: don't be cheap on plugs and get the ones stated in the video and/or in the owners manual
i would have double checked the gap with a wire spark plug gapper tool BEFORE installing the new ones
of course, do this when the engine is COLD
i would use a torque wrench and torque to specs as well (usually 13 to 15 ft lbs ~ too tight may strip the hole and too loose will pop the plug and go up to your hood)
also, if you read the comments there on the youtube video, he used anti-seize ~ with this brand you don't need it, but some others may use it ~ he put way too much on the spark plug threads if you want to put that on, put just a small dab and rub your finger around the threads
There's two main issues that cause this:
no spark; and no fuel.
No spark can have many causes, from a dead spark coil to a broken crank angle sensor. Can also be the coolant temp sensor.
Check for any error codes from the ECU.
Open the gas cap and see if the car swill start. You should be able to hear a buzzing from the fuel pump just after you try to start.
A crank no start concern is when your car has power to it, and when you try to start the car it will turn over but will not fire. There are two problems that are mostly associated with a crank no start concern.
Starter is Bad.
If your starter has failed, you might get a crank no start concern. If you happen to be stranded somewhere, I would try to tap on the starter. This is an old trick used by those in the know, and sometimes it will work so you can get your vehicle to a repair facility. The reason for this is because when a starter fails, it usually binds up internally. Tapping on the starter will sometimes free the internal parts temporarily and allow you to crank and start the vehicle. If this doesn't work, you may have lost power to the starter and will have to have the vehicle towed.
Fuel Pump Failure.
Another common problem for a crank no start concern is a bad fuel pump. A fuel pump does exactly what it says, it pumps the fuel from the gas tank through the lines and to the motor. If your fuel pump is bad your car may just crank and crank, but won't start. Ironically a quick fix for this is the same as the starter. Try to tap on the fuel tank to get the car started. This may allow the vehicle to run on what's called false fuel for a while, or at least until you can get it to the repair facility. If this method fails, unfortunately it's time to get the vehicle towed.
Electrical Issues
These days most vehicles will have some form of security system in place. The most simple form of security often causes a lot of problems. If your electronic ignition switch has a security feature on it, it can fail and cause the vehicle not to start. Basically what happens, is the car thinks the wrong key is in the ignition and refuses to allow the vehicle to start. Really the only repair for something like this is to replace the entire ignition switch for faulty operation.
not sure about yours but most cars they have pop clips. you will have a couple screws hiding under some plastic clips. then if its a manual window the crank would need to be removed they have a clip on the back side. a screwdriver can pop the clip off I use a flat piece of metal to get it off. and then its a matter of prying or sliding in some cases. to get the panel to move.some lift up. others just pull towards up. you wont know till you pry on the panel to see where its stuck and either find the screws or another clip.
No question, Get a manual with the correct tightening sequence and tourque settings. This can go very bad very quick if done incorrectly!! manuals are cheap at most auto parts stores.
The radiator fan will not normally have power. It is only when the engine coolant thermostat detects high temperature it sets on the fan relay which starts the fan. So it is likely the thermostat or the fan relay are faulty.
could be worn drive belts, try sprayin the alternator etc drive belt with wd40 before starting and see if no screaming ,if no sctreaming change belts, as these are never changed at the requried intervals
