    I had the same problem and kiss your car good bye. It is the timing belt and the more you try to turn it over the more damage you do. I was told it would be 3000.oo plus to fix it so it is sitting in a junk yard now. Sorry!

Engine Cranks But Will Not Start

For an engine to run, you need three things to happen inside the engine. Compression, fuel and ignition, without any one of these components the engine will not run.
Basic Checks:

A. Test Fuses. Test both under hood power distribution center and the fuse panel under dash. This is done with a test light tool. The test light should illuminate on both sides of the fuse, if not the fuse has failed and needs to be replaced.
B. Testing Fuel Pressure Test for proper fuel pressure with a test gauge on the fuel rail, most throttle body injection cars (TBI) are between 13 psi and 17 psi. and most (DPI) direct port inject systems are between 40 psi and 55 psi. If no or little fuel pressure is observed and there is 12 volt power present the fuel pump, the fuel pump needs replacing.
C. Checking Timing Belt Test for compression by removing a spark plug and insert a compression gauge. Crank the engine over about 5 seconds the gauge should read between 125 psi and 165 psi, if no compression is observed remove front engine cover to inspect timing belt or chain. Crank engine to observe cam rotation, if the cam does not rotate the timing belt or chain has failed. (note: if the timing belt drives the water pump it is best to replace the water pump at this time)
D. Test for Injector Pulse Remove injector connector to insert injector test light (node) or volt meter. Observe light flash or gauge pulse while cranking. If light/voltmeter doesn't respond, an ignition distributor/crank angle sensor (CKS) or an ignition module is most likely your problem.
E. Test for Ignition Spark Remove spark plug wire, insert an extra spark plug into end of wire, rest spark plug next to a ground source then crank engine. You should observe a blue spark between the spark plug gap and ground source. If no spark is observed, an ignition coil, ignition rotor or spark plug wires might have failed. (always keep hands away from engine when cranking)

98 olds aurora i turn key wont start. all else seems fine after a few attempps it will start any idea whats wrong?


You mean it cranks but won't start, or it just won't crank over?

If it won't crank, possibly a defective starter motor or starter solenoid. To be sure: when it won't crank, put a test light on the small wire to starter solenoid with key held in start position. Wire should have power. If it does, defective or failing starter motor or starter solenoid. If no power on the wire, check battery and starter connections for loose connection. Further testing requires a wiring diagram to see the whole starting system.

Won't crank


If the fuel pump is working and it won't crank, then it could be your starter. The easiest way to test that yourself is to use jumper cables hooked directly to starter. Yes that can be dangerous if done wrong. If you do, here's some pointers.
1 - Make sure the vehicle is firmly parked, E brake, neutral, wheel blocks, anything to make sure it won't move.
2 - A standard that's in gear will move when the starter turns
3 - The last time I did this I had the drive wheels off the ground, no chance of moving.
4 - hook up the cables to the terminals on the starter first, making sure the cables are not in the way of belts / fans etc. Then connect them to the battery, only briefly, if it cranks, the problem is with a fuse / wire / computer etc. If it doesn't crank, buy a new starter. Hope I helped, Grim

New Battery/starter and still wont crank.


car wont crank or car wont start? I would say your battery cables are bad,, acid gets in from battery and erodes internal cable parts... need a Meter to check it out.. put the meter on battery while someone tries to start it, if the voltage drops from 13.5 to 10 then it is trying to turn over, I always have the new starters tester before I leave a store, they are remanufactured in Malaysa and they use old parts in most of them..

HELP! My 2000 plymouth neon wont crank and no mechanic i bring it to can figure it out!!


If the headlights and dashboard lights are working but the vehicle still does not start, the ignition switch is most likely the problem. or a bad wire from switch. If your battery checks out, but the starter is still silent, it may be a faulty ignition switch. Turn the key to the on position (not all the way to start). If the red warning lights on your dash don't light up (and your battery connections are clean), the ignition switch is bad. If they do light up, turn the key to the start position. The dash warning lights should turn off at this key position (most cars). If you're not sure, turn on the headlights. When you try to start the car, the lights should either dim (a lot) or turn off completely. If they do, your ignition switch should be ok. If not, the switch will need replacement. check the wires to starter and see if you have power when car is switched on, do this first! good-day! if it cranks but does not start. check to see if spark and fuel, and check all fuses also.

Your starter solenoid is worn and going bad. Have the starter replaced and it should start every time after that. I had the same car, with the same problem. Change the starter.

Replaced starter but she still wont start


I assume you know that the starter turns over the engine,in a mechanical sense.
It has nothing to do with starting your vehicle,other than turning the ignition pulse wheel (Flywheel)

What help do you want?
Do you even work on your own vehicle?
