Why my car will crank but wont 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.

1997 thunderbird cranks and fuel pump comes on but wont start


Most likely the fuel filter is clogged. They cost around 10-15 dollars. Usually mounted somewhere along the frame rail under the vehicle. Just follow the fuel line and it will lead you to it. Also you will need a special tool to release the interior clips. The plastic tool works fine and is about 15 dollars. You can find everything at Autozone or a similar parts store. Hope this helps you.

2009 toyota corolla verso sr cranks but wont start


Any gas in the tank...?
Yes. Then
First check fuses. (Injector fuse, fuel pump fuse, head or main engine relay) It's not bad idea to check all fuses.

If all fuses're good (Not blow/burn)
-Next check spark and fuel.

Why wont my 1989 buick lesabre wont start ?


Does it crank? Or there's no crank no start? If it cranks safely get under the vehicle and bang on the fuel tank while someone holds the key in the crank position with the vehicle in park. If it starts it is most likely the fuel pump.

2002 chevy s10 2.2l no start condition. changed fuel pump and filter. plugs wires timing chain and gears. still not starting its cranking but wont turnover. i have spark but on the fuel pressure release...


The s10 have a fuel shut off relay to shut off fuel supply in case of an accident. They also have a anti-theft system that prevents fuel in case of theft.Pull the fuel line off and crank the engine to see if you get fuel. Sorry I can't be of more help but without hands on vehicle it is hard to tell.Also your fuel pump maybe sounding like it is pumping. In other words it may be running but not pumping fuel it mat have a ruptured diaphragm in the pump.The pump is running but not pumping fuel. Pull the fuel line off at the fuel filter and turn on ignmition or crank the engine you should have about 50PSI coming out.If you don't install new fuel pump.These vehicles are common for this problem the fuel pump runs but does not pump fuel or not enough pressure these vehicle require 57 PSI to start if it has less than 51PSI it will not start unless you use starting fluid then it will run.It will run with less fuel pressure it will just not start with less than 57PSI.

Hope this helps

Cranks but wont start ,sputters but wont start has fuel in tank, it is a 1999 cougar V-6


Hi!!It sounds like your fuel pump is not working. Check fuel pump relay on engine compartment fuse box have somebody to turn the ignition key to the RUN position, DO NOT CRANK ENGINE (feel if the relay clicks when the key is turned, it will only be energized for a couple of seconds and then you should feel when it gets de-energized. if relay is OK, remove the fuel tank gas cap and repeat the same key operation, listen to the fuel pump coming in, again this will be running only for a couple of seconds, try a few times until you are sure one way or the other. If fuel pump works, then replace fuel filter and try to start vehicle. If vehicle does not start. You need to check fuel pump pressure. borrow a tester form Autozone or similar auto parts store. The fuel pressure should be between 30-40 psi with key ON engine OFF. If pressure is off either way, replace fuel pump. Here is how to hook up the fuel pressure tester 1kbron_71.jpg
Good Luck! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Vehicle just keeps cranking wont start.


Make sure that your fuel presure is up to at least 60 psi if not that could be your problem. If not, make sure you are getting spark, if not could be your Crank sensor or ingniton module ECM. Usually if your Engine control module wouldn't be bad because of your fuel pump is working, but may not be putting out the proper pressure for the fuel system. Fuel Pumps are a Problem with that year..
