What do I need to do it is spin over but will not crank


Make sure fuel is reaching the engine as a first step. Have someone check the TDC crank sensor for you.

3) Spark: From battery to spark plug

The battery is the source of stored electrical power in the vehicle. A voltmeter between the terminals of a healthy battery should read 12.5 volts. A reading of 12.2 volts indicates a flat battery and a reading of 10.4 volts indicates a dead cell (each cell beingabout 2 volts). A battery should be capable of sustaining high current, as needed by the starter motor when turning the engine over. When the car is running the voltage measured across the terminals shouldbe between 14.2 and 14.5 volts. The value is the voltage being supplied to the battery by the output charge from the alternator. THis charging voltage should not alter much when additional load is applied to the battery (head lights on etc).
When the ignition key is turned to the second position,often referred to as 'key on engine off', all car functions are powered up including lights and fuel pump. When the key is turned to position 3 many ancillary functions are temporarily interrupted to allow the battery to meet the extra needs of the starter motor. Electrical charge from the starter switch passes through a master fuse and starter relay before energizing the starter solenoid. The starter solenoid moves the pinion gear on the starter motor to engage with peripheral teeth of the flywheel. Simultaneously, heavy copper contacts are bridged by this same movement causing the starter motor coils to become energized thereby turning the engine over.
During the ignition process electrical charge passes through the primary windings of the ignition coil(s). The engine control unit (ECU), taking signalsfrom the engine crank position sensor, collapses the field of the coil(s) appropriate to the cylinder requiring ignition. As the field collapses the secondary coil windings discharge very high voltage through the high tension lead to the spark plug. The charge is so high that at the spark plug gap the charge jumps across with a spark. The compressed fuel air mixture in the cylinder is ignited by this spark.
Checking the spark process starts with the plugs. The condition of the removed plugs reveals a lot about the nature of the ignition within the cylinders. Dark sooty deposits indicate overly rich fuel air mix and glazed plugs indicate overly hot lean mixtures. Removing the plugs (with the fuel pump relay unplugged) and holding the screw threads to the cylinder head whilst turning the engine over will reveal the quality of spark. The spark holders and leads should be examined for discharge through the insulation to the cylinder head. Removing the leads from the coil should reveal sparks emanating from the exposed connectors. Failure to see sparks at this point indicatesa failed coil (especially if neighboring coils show good spark) or a failed crank sensor if all coils show no spark.

Car keeps cutting off just got a new starter, battery, and alternator


check the battery connections really good and check the power distribution center really good,sometimes the wires will get corroded and cause that too happen,it sounds like you just have a bad connection either to the distribution center or on one of the cables,that will cause what its doing,i own one of those and they will do this sometimes,good luck.

My rave 4 will not start... it is not the battery, could it be a fuse? how do I tell and what do I do?


If it is not the battery, check its connection/terminals, DO NOT hammer terminals as this will loosen the chemicals on the battery plates shortening its lifetime. Also check the large wire that goes from battery to the starter. Tighten screws/nuts as you check on the wiring. Also check on the fuse as you have said.

If there is only a clicking sound is heard when you start the car, fuse is okay and check again on the battery's power for it might be discharged.

If again starting it and a starting sound is heard but could not proceed to run, then the defect goes beyond the fuse and battery. Could be on the injection system, spark plugs (as the case maybe), fuel system.

The car do not starter and the light oron do not strarter jack in up it starter and run 2003 buick lesabre


There are some possibilities which you will have to check in this case:--

1) First of all check the power and voltage to the battery. With meter it will show exact 12 volt if the battery is charged. If the voltage is less get the battery charged at local auto repair shop. If the battery is internally drained and not getting charged then its time to replace the battery.

2) When you crank the car do you see spark coming at the spark plug? If no then its time to check the spark plugs and coil pack. If the spark plugs are not worn out and looks new then its time to check coil pack. The spark plug gets power to spark from coil pack.

3) The other thing to check in this case is the starter solenoid of the car. If the battery is charged and you start the car then it gives power to the starter to start the car. But if starter is faulty or not connected properly then car will not start.

4) The other thing to check in this case is fuel in the car. If there is fuel in the car then check the blockages in the fuel pump if the fuel pump looks proper then check the fuel filter above the fuel pump.

5) If all the above possibilities mentioned above checked out OK/perfect then it's a electrical issue and the wiring's in the car needs to be checked. The car gets power from the battery to get started. so the wires from battery needs to be checked one by one.

The battery to starter connection has power.the battery is ok.but there are many other possibilities related to battery and its other connections,the spark plugs,the fuel pump,the fuel itself,the sensors(o2 sensor,maf sensor)the valve(IAC valve,egr valve). Most probably the spark plug,the coil pack and crank shaft sensor.This 3 are not getting power to get the car start.

There are some possibilities which you will have to check in this case:--

1) First of all check the power and voltage to the battery. With meter it will show exact 12 volt if the battery is charged. If the voltage is less get the battery charged at local auto repair shop. If the battery is internally drained and not getting charged then its time to replace the battery.

Ford maverick 1993 petrol wont start its getting petrol and good spark but just wont fire up anyone can help me?


Is the timing correct? Is the battery turning the starter over fast enough? Did you check the plugs with the spark checker tool that goes in between wire and plug? If so the plugs may be bad not giving the spark actually inside the cylinder.

Not starting - power to spark plugs engine won't start


You checked for, and have spark, next check for fuel to plugs. After several attempts to start, pull a plug and look for evidence of fuel (should be damp after several starting attempts) Do you hear a humming sound when the key is turned on to start? That would be coming from the gas tank, and is evidence that the fuel pump is functioning. If no gas, no humm, check for power to fuel pump. If there is power to the fuel pump and connections are ok, the pump is bad and needs to be replaced. If humm present, try changing the fuel filter, there's a chance it's plugged up. Let me know how it goes.

93 oldsmobile quad 4 2.3 one piston is not working wet spark plug


If you have a stethoscope, listen to the injector while the vehicle is running, it could be stuck open. If you hear it pulsing the same as the rest of the injectors, then unplug it, let the engine run so it can get all of the unburned fuel out of cylinder (you said the plug was wet), take the plug and coil from cylinder number three, install them in cylinder # 4, put the coil/plug from 4 into 3, reconnect the injector, and see if the problem moves to cylinder three. Next if the problem does not move to cylinder 3, then you have an issue with either the wiring to the connector at cylinder # 4, or you have a mechanical failure. Remove the valve cover, check the valve springs on # 4. make sure they look the same as all others. If so, turn the crank and further inspect them. If they are mangled, remove the head. It needs to be repaired, and check the piston for damage. You could also do a compression check to rule this out.
