Hi i drove my car this morning and when i got back i listened to the radio a while with the car in the start position but not cranked. now when i try to crank my car it is not making any noise and it will not crank...i dont know whats wrong ive tried to get a jump but it still wont crank...could you please help

Won't start how ? When your the key to the start position what happens ? The engine spins but won't start an run . this a crank no start condition . If nothing happens when you turn the key to start ,this is a no crank no start condition . Need to be clear on this so we know what to have check . If nothing happens when turning the key to start position ,try moving gear selector to neutral - park neutral safety switch . If when you turn the key to start an the engine does spin but doesn't start an run ,check for spark ,fuel pressure . see what's missing .

Hi
Chances are sticking motor in starter
try tapping the starter motor and re-start the car again.

that will confirm if its defiantly starter

Make sure the alternator is producing the rated amperage. One or two blown diodes inside the alternator will reduce its output. Test for a draw. You do this by taking off a battery cable and using a multimeter set to measure current connect it to the battery cable and then to the battery post. Now start removing one fuse at a time while observing the current draw until it stops. Whatever circuit that the fuse controlled is the problem.

This is most likely the battery, sometimes you can have enough power for dome lights and radio, but not enough "Cranking Amps" to start the vehicle. Charge it, or take it to an Auto zone or something. They will charge it and test it for free.

cannot seem to get the wiring diagram to post on the other thread, so trying here. Check continuity of crankshaft sensor wires.

need to find out if you have a fuel or spark prob., then it can be diag. if you have a security system, try locking and unlocking from outside door lock on driver side. then try starting it, or you could disconnect batt. for about 30 min. to reset everything and then connect batt. back.

Sounds like a failing crank or cam sensor; does the car have spark? Remove the main lead from the coil and position near a grounded piece of clean metal, place it @ 1/4" away and crank engine over for 2-3 seconds and watch for spark; if nothing it will give you some direction. If there is spark check for fuel injector pulse; rent some NOID lights from Autozone or such and unplug one injector and plug in NOID light and crank over for 3-4 seconds if you get a pulse of light the injector pulse should be ok. Next area I'd check is fuel pump, you'll need to check for fuel pressure, some special tools needed here plus your working with gasoline, take care of no spark/no flame. You may be able to listen for your fuel pump...turn off items such as fan, radio and such, make it quiet crank over motor for 2-3 seconds listen for a click (that would be your fuel pump relay and when you let go of your key you should hear the fuel pump run for just a brief second, I expect pump in the tank.
One of these I hope should get you in the proper direction.
I hope this may have helped you,

Crank sensor. Next time it does this spray some water on it and see if it cranks. Its by the crankshaft pulley towards front of car.

water intrusion in the junction block is kina what it sounds like to me.
they were doing a recall on this vehicle.
there was corrosion happening to the wires.

Hello,1ºdesmount ignition coil and check if smeel burned,if coil is ok 2ºturn on ignition and listen if fuel pump is working(lift up back seat to listen better) or can be cranckshaft sensor(check with multimeter on OHM)
