Does the starter make a noise when you crank it? If not, first make sure you have 12+ volts in the battery and good battery connections. If the battery has less that 9 volts, then replace the battery. Try using a jumper box or a set of jumper cables from another vehicle to start the car. If you can see the starter, have someone strike it with a hammer while turning the key to the crank position. If it starts, replace the starter.
A common problem that's surfaced a great deal lately is a car/truck that
starts fine when the engine is cold but won't when the engine is warm.
Most of the time, the car will require a jump start with a warm engine
to get it to start. Most mistakenly assume a bad battery and change it
out, only to have the same problem. What happens is most starters don't
just "quit" when they are defective. A bad starter will usually start
your vehicle when it's absolutely cold. Once warm, the starter will
behave as follows:<br />
<ul>
<li>No power</li>
<li>Click then nothing</li>
<li>All other electrical is fine (headlights, stereo, alarm etc)</li></ul>
If your car or truck won't start when the engine is warm, but starts
fine when it's cold, you most likely have a bad starter. Although
replacing the battery is less expensive, it rarely (if ever) will
resolve this issue. Consider the age of the car / starter when these
symptoms occur. If you have an older vehicle (older than 5 years) then
replacing the starter is a good place to start prior to buying other
electrical components (battery, alternator). <br />
<br />
Always bring the vehicle to a shop that offers a free electrical
diagnostic test to confirm the electrical system is sound to rule out an
electrical problem first. If the electrical system is sound, I'd go
ahead and replace the starter. <br />Although this tip will show under the Lincoln category, it applies to all makes and models.<br />
How to voltage drop test starter motor circuit
Looking at a wiring diagram to see what all is involved in starting your vehicle . Free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. Year , make , model and engine size. Then under system click on engine . Under subsystem click starting . Then click the blue link . You will see the ignition switch , transmission range switch ,starter solenoid . Testing the electrical circuit with a volt meter till you find the problem . Check the heavy red cable from the battery positive to the solenoid . Starter Voltage Drop
Park neutral safety switch maybe be the reason for the no crank ! Try putting the vehicle in park ,then try to crank the engine . Testing the electrical circuit is the best way to trouble shoot this problem , along with do a voltage drop test on the starter circuit ! This will test the battery cables an connections . Starter Voltage Drop How to voltage drop test starter motor circuit
Does it have a manual or automatic transmission ? Manual ? clutch switch . Looking at a wiring diagram I also see a starter cut relay ! http://www.bbbind.com/free_tsb.html Free wiring diagrams . Enter vehicle info. year , make , model and engine size . Under system click engine , under subsystem click starting . Then click the search button , then click the blue link ! Check the starter cut relay also . Videos on youtube showing how to test a relay controlled circuit !
A starter motor problem won't cause the car to stop, You need to make sure that the earth leads from the battery to the body and to the motor are tight and that the surface they bolt to is clean, there could also be an issue with the electrical switch on the back of your ignition.
Troubleshoot first and then change parts! What was the original problem? It just won't crank over? The alternator just charges the battery the voltage regulator keeps from putting too much of a charge into the battery. Was the battery going dead? Did the vehicle start when jumping it with jumper cables? Too many unanswered questions to offer help, sorry.
Check the starter and the starter relay or fuse. A client of mines car was doing the same thing, it ended up being two issues, the starter not working anymore, and a relay that was bad. If I am not mistaken everything should be labeled in the fuse box under the hood and will tell you where the fuse/ relay is for your vehicle
I would change all three. alittle expensive, but on this old of a vehicle I would not waste time and trouble. if this doesnt work then maybe some ignition problems. But i would guess that battery, starter, alternator, should do the trick
