    how did u get the battery tested? a voltmeter only reads volts. u want amps, since that what is what ur battery needs to crank over the engine. also u could have a cell going bad, not enough electrolite in the battery.

SOUNDS LIKE U HAVE A BAD IGNITION SWITCH. MY EX HAD THE SAME PROBLEM WITH HER CAMARO. I EVENTUALLY BOUGHT A KIT FROM PAINLESS: http://www.painlessperformance.com/ THE KIT BYPASSES THE STOCK SOLENOID AND GOES THRU A FORD STARTER SOLENOID. THE JUICE GOING THRU THE WIRING EVENTUALLY DESTROYS THE IGNITION SWITCH CAUSING THE SYSMPTONS UR EXPERIENCING. CHANGE THE IGNITION SWITCH AND INSTALL THE KIT.

Sounds like you may have a bad ground cable. just as a test you can run a thick wire from the battery to the frame or another good ground on the engine see if this makes a difference if it does replace the ground cable.

Why wont my jeep start some times put lots of new parts in and its been at a jeep dealer for 2 weeks and they cant figure it out its like the Batt has been unhooked it will start fine then the next ti
you meant it wont crank? , right?, no A/T car starts, until cranked. so......what is it.????????
if you learn the art if testing, you win this battle.
here they are.
NO CRANK 101: (rule 1, it must be failing to find a cause)
it not failing, nobody can fix working cars, but they will try, and charge you for doing nothing at all. your choice.
its failing....
  1. does it crank with jumper cables to running car?
  2. are all 4 ends if the battery cables clean and tight?
  3. when you hot wire the starter solenoid, keys in pocket , does it crank now?, if yes, good, if not the starter systems are failing.
  4. if yes, it cranks now, then the KEY line is dead.
ill stop here,,,,, if key line is dead, wiggle the shifter, or try neutral cranking.. at shfiter. (bingo that>?)
battery at 12.6vdc charged and rested before starting the tests.
use a cheap voltmeter.

put what parts in?, do tell , the battery would be first. no?
try a loaner battery?

if the car always cranks then say so, that is called
cranks but does not start. period.
answer the simple questions and we can take you to the cause.
my voltmeter has never lied to me yet, in 50+ years.


lets say it cranks all the time.
cranks but does not start

Low voltage
does it crank fast, at 250 spec RPM?
no year, no joy, all cars have a year,
and and engine option (displacement size???)
my wild guess, is it wont crank or cranks dead slow.
right?
and the battery is DISCHARGED. right,
use jumper start cables. start now?
that be first.

wont crank
cranks perfectly but wont start ?(check for spark, x number of cyl)
spark good, try test fuel
test fuel works for 3seconds and stalls,. then fueling problem , ask.

2008 MDX will not start just clicks
corroded battery terminals, clean them, and try jumper cables.
both way use same crappy terms.
what transmission A/T or M/T my guess, A/T
so wiggle the gear shift, try neutral starts. this is the PRNDL switch
wiggling it finds new fresh brass on the switch contacts,
wiggle as you crank the key.
if that fails
then hot wire the starter solenoid.
if that act causes cranking, then the starter and battery and cables are good. and means the KEY LINE is bad.
if no crank , hot wired, then that means the starter bad. (battery good , battery charged in all cases)

see hot wiring here.

http://www.fixkick.com/nocrank.html

in a nut shell
1: battery charged at 12.6vdc. rested.
2: chock wheels, all brakes set., in PARK (or M/T in neutral.)
3: gain access to the starter
4: unplug the key line (that is the tiny wire) on starter solenoid.
5: keys in pocket
6: jumper the solenoid tiny wire, to the big outboard lug on solenoid.
grrrrrrrrrrrrrrrrrrrrgggggggggggggggggggggrrrrrrrrrrrrrrrrrr
it wont start, keys are in pocket.
the starter is good, i save you 1/2 the diagnosis. in 1 simple step
put the wire back removed in #4
if its dead, the KEY line is dead. ask how to fix that. next. i f so be...

I jumped car off it crunk on its own fora day,then batt went dead again,this time it won't jump off. It wants to crank but won't turn over.
not sure what you said but.
seems the battery is discharging,? 12.6v is fully charged,
own a voltmeter?
try a good loaned battery , does it start the car,?
i think you meant?
i can jumper cable start my car at any time. (off another running car)
but after running my car, the battery discharges and it will not crank at all. right?
this means ,the charging system on your car is bad.
if the starter cranks great, then the engine is flooded or is in great need of a tune up (sparkplugs etc)
if flooded try the super secret in the op guide, crank with throttle wide open , this magic trick cuts all fuel injection allowing the flooding
to purge away, and eventual starting.
my guess 2 is the car wont start, so you crank the battery flat
you jumper start it and it runs. (luck)
then day 2, same deal cranks ok but wont start.. ever tune up the engine?

1997 chevy blazer s10 cranks but wont start
You have a new battery and it cranks. Turning over is cranking. You are saying it won't start after sitting for six months? What is an old mechanic? Was the cable installed at home during the one year layoff? It sounds as though you failed to hold the old mechanic responsible for installing the correct cable or adjusting the one you have ,so it will start. You have a safety switch issue by the sound of it. Make sure you have the right cable and then find out how to install and if applicable,adjust properly

Ignition
Sounds like the battery is dead, you have just enough power to have the lights come on, but no cranking of the starter. Try putting the battery on a trickle charger, or hook up jumper cables to another car which is running. Let it run with the jumper cables connected for two mintues before you try and start your car.

1999 blazer wont start??
Your battery is either faulty or ther is a parasitic drain, have it checked out at parts house. With a good battery installed, spray some starter fluid into intake housing. If it starts, then dies, you have fuel pressure/delivery problems. Can you hear the fuel pump run when you turn on the key? Hope this helps.
