MY PLYMOUTH GRAND VOYAGER 'S HEADLIGHT'S AND DASH LIGHTS WORK, BUT THE ENGINE WON'T TURN OVER. THERE IS NO SPARK COMING FROM THE ELECTRICAL WIRES.


When you say no spark, are you talking about the spark plugs, or just the general wiring?

If the engine won't turn over, then it isn't moving, and if it isn't moving then you need to check the following in this order:

1) Does the battery have power i.e. around 12.4 volts or over?No? Charge, test or replace battery.

2) Do the car's head lights dim considerably if turned on when attempting to crank? Yes? Possible lack of battery charge or faulty battery.

3) Assuming the battery is fine, can you turn the dash warning lights on and off with the key? No? Faulty ignition switch.

4) Is there a click sound when you turn the key, but no starter motor spin? Check starter motor connections or replace starter motor.


If none of the above prove to be of help, then please report.

I turn key and starter spin but will not engage flywheel.


You have one of two problems: Either the starter drive on your starter is defective and is not engaging the flywheel to crank the engine, or the flywheel has some broken or damaged teeth that are preventing the starter from engaging.
Starters come in a variety of designs. On some, the solenoid is mounted on top of the starter. When you turn the key, the solenoid routes current to the starter motor and at the same time pulls a lever that slides the drive gear mechanism out so it will engage the flywheel and crank the engine. If the solenoid is weak or damaged, it may not be strong enough to overcome the spring tension that retracts the drive gear. So the starter spins but doesn't crank the engine.
On other starters, the solenoid is mounted remotely. When the starter motor starts to spin, it ratchets out so the drive gear will engage the flywheel and crank the engine. If the drive mechanism is damaged or hung up, the motor may spin but not crank the engine.
Regardless of what type of starter you have, it will have to come out for further inspection. The drive gear (which is sometimes referred to as a "Bendix drive") should move out when the starter starts to spin. The drive gear usually has a one-way clutch that is supposed to protect the starter against damage if someone keeps cranking the engine once it starts. The gear should turn one way but not the other. If the gear is locked up or turns freely either way, the drive is bad and needs to be replaced. If the drive can't be replaced separately, you'll have to replace the entire starter.
Starter Testing If the drive seems okay, the starter should be "bench tested" using jumper cables or special equipment designed for this purpose.
CAUTION: Be careful because a starter develops a lot of torque. It should be held down with a strap or clamped in a vice (be careful not to crush or deform the housing!) before voltage is applied.
A simple no-load bench test can be performed with a battery and a pair of jumper cables to see if a starter motor will spin. But this test alone won't tell you if the starter is good or bad because a weak starter that lacks sufficient power to crank an engine at the proper speed (usually a minimum of 250 to 500 rpm) may still spin up to several thousand rpm when voltage is applied with no load.
A better method of determining a starter's condition is to have it tested on equipment that measures the starter's "amp draw." A good starter should normally draw a current of 60 to 150 amps, depending on the size or power rating of the starter. Some "high torque" GM starters may draw up to 250 amps, so refer to the OEM specifications to make sure the amp draw is within the acceptable range.
If the starter does not spin freely, or draws an unusually high or low number of amps, it is defective and replacement is required.
An unusually high current draw and low free turning speed typically indicate a shorted armature, grounded armature or field coils, or excessive friction within the starter itself (dirty, worn or binding bearings or bushings, a bent armature shaft or contact between the armature and field coils). The magnets in permanent magnet starters can sometimes break or separate from the housing and drag against the armature.
A starter that does not turn and draws a high current may have a ground in the terminal or field coils, or a frozen armature.
Failure to spin and zero current draw indicates an open field circuit, open armature coils, defective brushes or a defective solenoid.
Low free turning speed combined with a low current draw indicates high internal resistance (bad connections, bad brushes, open field coils or armature windings).

Jeep stalls gauges don't work windows and locks and radio don't work


when you state it wouldn't crank, do you mean the starter won't engage or that it just spins over and doesn't start? if no gauges or no starter engagement, then check the battery, battery connections,and the starter for excessive amperage draw. if the starter spins and the engine won't start, then check crankshaft position sensor first. the crank sensor is a more common failure than the distributor or any of the other things you mentioned.

My 96 jeep Laredo will not turn over. I've checked


sorry turns over means ZERO
the crank shaft can spin or not
the starter can in fact spin and crankshaft not.
and some think turns over means, engine runs. now that fact makes turns over, a dead statement.

the word is cranks over, the engine cranks over robustlyl
and then the engine runs.
then runs for more that 3 seconds, and the ASD relay holds. (step by step his works like this ,93 to now)

wont crank ? (clear statement in fact)
cranks ok, (crank shaft spins fast) can be seen and heard.
runs for 3 seconds? and stalls (ASD relay drop out) can be seen.
runs for 5min and stalls. (complex)
runs for hours and stalls. (even more complex)
all are key facts to the solution.

tell more..... tell all it does good bad or ugly
for better suggestions!

Starter works fine but won't crank engine. the pick up has to be given a push first before it starts


If the starter is spinning when you try to start but doesn't spin the engine over then you most likely have teeth missing off the flywheel ring gear. The facts that you say you have to push it and then it starts means the flywheel position changes and the starter has good teeth on the flywheel to engage. To confirm this next time the engine won't crank over remove the starter and look inside at the flywheel for missing flywheel teeth.

Any idea why it takes a few turns of the key to start my truck? There is 59000 miles on it and the last 2 mornings the truck did not want to turn over. it eventually did, and would start fine in the work...


You have to be specific about the engine turning over

That is done by the starter circuit

Some people call that cranking

Some people also say it won't crank, when they mean
it does crank, but won't start

Not turn over the engine -----

Old & Weak Battery
Dirty Battery Cables
Worn out Starter Solenoid -- you can buy & replace
without getting the entire starter
A bad Starter

Define - It attempts to turn over but won't catch and run ???? When you turn the key to start does the starter engage an spin the engine ? This would be a crank no start condition . If the starter doesn't engage an spin the engine this would be a no crank no start condition . Sorry to ask but i have only been an auto tech for thirty years an have heard a lot of different discriptions for these simple actions . crank no start or no crank no start . Very different diagnostic procedures . So when you turn the key to start , does the starter engage an spin the engine ,but won't start an run ?
