Try the following procedure to reset the Passlock;

30 Minute Learn Procedure (requires no tools)
1) Turn ON the ignition, with the engine OFF.
2) Attempt to start the engine, then release the key to ON. (engine will not start)
3) Observe the Security telltale, after approximately 10 minutes the telltale will turn OFF.
4) Turn OFF the ignition, and wait 5 seconds.
5) Repeat steps 1 through 4 two more times for a total of 3 cycles (30 minutes). The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.

IMPORTANT: The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

In other words, don't forget the final step 4 before you try to start the car.

6) Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password.

Where is fusiable link in a 2001 jeep grand cherokee


4.0L or 4.7L engine> the park switches are different.

you pulled a starter with out removing battery neg lug?
is that it?
your post makes it hard to see what the story is.
you replaced starter because car would not CRANK
or
you replaced starter, and shorted out the big cable and boom
and now all things are dead. what?
ill assume car would not crank one day
and you gue$$ a bunch of parts and guessed wrong,
guessing is very expensive.
------------------------------Testing wins--------------------------------------
so no crank 101, posted 100 times. ILL ASSUME it's a A/T tranny.
(im ignoring new parts, i never assume anything works i test it)

  1. check all fuses in all boxes. using a voltmeter. 12vdc both sides key on and battery cables lugs area all clean and tight x4 ends.
  2. you check battery volts its 12.6vdc rested, good.
  3. you crank, and the solenoid just clicks. or only the starter relay only clicks, (more later on that)
  4. you see that battery voltage never drops below 11v and crank time. (11v is typ, tad less if in Alaska, or bad battery or not charged fully)
  5. You then jumper cable crank car, off a running donor car ,just like Mr. AAA tow does.... same to a fault. (google how) (hinting your battery is good, I have a battery load tester so can check)
  6. if this cranks ok, the battery is bad. (happens or is discharged)
  7. car still will not jumper crank.
  8. we next hot wire the starter small wire to big lug. keys in pocket. Called hot wiring a starter solenoid.
  9. engine does not crank, starter bad. or may be battery cables.
  10. engine does crank nice , my keys are in pocket ,see?
  11. ok starter is good, at test 10. so we now know its ok. easy huh>
  12. now we know the key line is bad. 1 wire. end to end. easy.
  13. you try to start in neutral, omg it starts. bad PRNDL switch.
  14. or its bad starter relay.


now we show how it cranks. good starter and battery (& cables)
keyon,
put shifter in to park then neutral and crank.? fails both?

the starter relay must close cranked, if not, bad park switch or bad relay
in this moment (cranking) there must be 12vdc across the 2 relay coil pins.
pin 85 and 86 with volt meter, if 0v, the PRNDL switch is bad.
or on 4.7L the TRS switch.
if the relay closes, then jb fuse f31 is ok and pdc f8 must be good.
and you then turn key to crank. and relay pin 87 goes to 11v to 12v.
this then is a single wire that goes directly to the starter solenoid
tiny wire , it goes to 12v and starter cranks, 11v what you see here
unless in alaska , less. (10v ?)

see red arrow what is voltage there cranking?
we can go fast , if you just do that.

25513501-qtmfudt4eg5vdkejwfy5ompz-5-0.jpg the transmission switch grounds the lower coil,here.
if not the starter will be dead forever.
both fuses must be good, or same.
12vdc arrives at top left fuse, and is hot only cranking.
if the right fuse, glows above the relay can not send power to the starter solenoid.

The car wont start. I know its either the starter or just the cyllinoid to the starter. Im trying to take off the starter but I cant seem to locate the bolts. How do I take the starter off?


  1. why do that ?, why not post the symptoms and ask for help.?
i suspect you meant the engine will not crank. ????????????
no engine starts unless, cranked or push started (my stick car starts 3ways, starter cranked, push started or gravity(hill) started.
my guess is this Esteem is A/T tranny. and only 1 way.
And will not crank. here are the steps and logic.

  1. all fuses good, battery lugs cleaned.
  2. jumper cables, on your battery to other car, running.
  3. it crankes and runs , your battery is dead or only discharged.
  4. so you find it dont crank jumper cable started.
  5. the means its 1 of 2 things, bad starter or bad key LINE>
  6. so you then , hot wire the solenoid, on side of starter , it has 2 big lugs and 1 tiny lug, keys in pocket you jumper the tiny lug to big outside lug, (battery lug +)
  7. you find out the started cranks now. wow it works. i saved you 4 hours labor and trips to store and all that bull. THE KEY LIKE IS DEAD.!
  8. if it dont crank now the starter is bad (with charged battery)
  9. ok it cranks hot wired, it wont start cuz key in pocket for safety.
  10. you then do these tricks see here.
  11. http://www.fixkick.com/nocrank.html#tricks
  12. see the other tests there, and the hot wire too. and lots more.
  13. there is no need to guess, if you have a voltmeter, 100 points.
  14. The rested battery voltage should be 12.6vdc if not its discharged. so charge it.

Location relay


no model Honda stated, nor year, 1973?
my guess is
car fails to crank, am i right,?
ask how to trouble shoot NO CRANK (easy)
if engine CRANKS, ask who to trouble shoot that (longest book on earth)
ever clean the battery lugs this decade?
no crank, does car have A/T o r M/T tranny, not stated.
did jumper starts or known good battery (fully charged) crank motor fast (y/n)
yes, bad battery
no, bad cranking system. (its a system not 1 part)

cranking dead.
i hot wire the starter, soleniod.
motor cranks but dont start (cuz keys are in my pocket for safety)
no crank is bad starter or bad battery cables
cranks fast. starter and crank shaft on engine spins normal
cause,bad key line.

post results. we can work a bad key line, after post tranny type.
the above cuts the problem in1/2.
1: bad cranking system.
2: bad key line.


if battery is just discharged, its a bad battery or bad charging system.
owning a charger solve this as is using a voltmeter on battery after a good start.

2005 Cadillac CTS tried to crank my car all it will do is one click i took the battery to go get tested and it was 12.3 amps they said it tested fine. So i put the battery back in and same issue 1 click i...


12.3 amps is a bad battery , 500 amps is good, but you meant volts
sure. (by the way sir your battery is discharged, gets forgot?)

12.3 volts rested is a discharged,state ambient temp and can tell by how much using SOC tables.
try jumper cables, try a fully charged battery, 12.6v is fully charged at room temp, rested. barrow a charged battery for friends car.

State of charge.. at room temp.12.3 is 50% charged,
the shops dont tell you that, just GOOD battery, bad,
its your job to charge, it
then when cars starts, the alternator takes over, 100%

the reason you are not going good ,is because no voltmeter in hand. For SURE.
guessing dont work here, only tests and measurements.

1; can you try turning the cars crankshaft by hand.?
siezed, bingo
2: can you hot wire the soleniod small pin to the outside big pin
like here,
http://www.fixkick.com/nocrank.html#test1
if the battery is weak, this test is useless. on all cars.
if it works then the key line is dead
if not the battery ,or cables or starter is bad.
there are 3 parts to a starter,
i repeat, the battery (charged) the cables and the starter.
engine turns by hand. yes.
those are all facts.
another tack.
voltmeter across battery lugs.
crank 0v bad battery or shorted or siezed motor.
12v, starter dead open circuit.
10v typical with fast cranking.
you can see this in 2 dimensions. here.
time is the horizontal axis.

It won't start: new battery, have lights, it just clicks when you turn the ignition switch


you mean it wont crank, it must crank to start.
1: bad starter system
2: weak battery even a new battery can be weak.
if you dont charge it first.
or if it starts ok then wont later, that means cars charge system failure.

can you jump start engine? with jumper cables.
that be a big clue there, proving starter works but battery was weak.
if the battery is fully charged.
you can hot wire the starter solenoid, (tiny terminal)
if car cranks now, the key start wire is failing.
A/T or M/T tranny? both use different path here....??????

if you cant hot wire it, then that means the stater is bad
the cables bad or the battery is not really connected.
or possible the engine is seized, can you hand turn over the engine at the front crank bolt (CW , facing rear, in neutral)
if not motor is seized.
some times even the starter and rig gear can be seized.
the starter can be bench tested. too.

Ok my 1983 camaro has a v6 in it and every time I want to start it I have to hook it up to a portable battery charger and start it up like that but now it won't even start up. Even when the battery is...


Sounds as though the battery is no good,
unless you know otherwise & also had it tested
Charging a battery doesn't address it's internal
condition
You have battery cables that corrode inside & can be
voltage drop tested
You have the starter & solenoid,ignition sw & such, to name
a few,lots of possible causes & things to check

My car won't start, i tried to jump it but nothing happened


Turn the key to on position for 20 mins for the key relearn process to complete.
But....if you get a good click and have a fully charged battery but no cranking from the starter motor........you may need a starter.

Have a 1989 F250 diesel put a solinoid on the starter and now it just clicks


JU JU Fruit. Your battery is low. You cannot get enough voltage from the system through the ign switch to pull the solinoid in. You have enough voltage to crank the starter, but I am sure this is marginal as well. The starter cranking is all about amps, the solinoid pulling in is more about voltage. Put a volt meter on your battery and I bet it reads less than 12.6 - what a fully charged battery should read.

On the F250, clicking solinoid is also due to low battery voltage. Pull both batteries and have them fully charge and checked. Stores like advance auto parts will dothis for you for free. Clean all of the terminals and reinstall. If batteries are OK, have thew charging system checked also. Again Advance will check it for you

Good Luck
