I have 2006 dodge charger Rt. I brought new battery an starter an have alternator rebuilt an my car still wont crank


There should be power o the small terminal of the stater anytime the key is in the crank position. I would start with checking that. If there is no power you will need to trace that circuit back.

That wire gets power from the starter relay and the relay gets power from fuse 20 in the TIPM (underhood fuse box). The starter relay control side starts at the ignition switch. The pink with dark green wire should have power with the key in the crank position. That power goes to fuse #10 in the TIPM. it then goes to the starter relay. the starter relay is grounded by the PCM.

Give that a whirl.

I have a96 isuzu trooper just had the starter checked and its good but still not doing anything when i stick key in theignition to start could it be the security system


NO CRANK. 96 USA car,(are my answers) check all fuses 1st !
C1 and FL1 and FL3 fuses good?
4wd ? or 2wd. auto or stick shift?
which engine? size? and cyl count....??????? 2.6 or 3.2liters?
wiring varies by engine type, so i guess more....
Does it crank ok with jumper cables (?) to a running donor car?
can be lots of things, gee the IMMO light in the dash is clear.
is it glowing? (the operators guide covers that.)
is this a USA car or Canada? some are different.
got a voltmeter even a $10 walfart meter works perfect.
or do you want to gue$$ and go broke fast. its your cash but/?.......
3.2 v6 shows no IMMO pins on the PCM...... so...?? in 1996

  1. battery dead, or discharges or terminals at 4 ends bad on cables.
  2. Fuses good.?
  3. turn key does CEL lamp glow?(cluster) if not , its not going to start with a dead ECU.
  4. no is the IMMO lamp glowing.
  5. key to start, (crank pos) silent.? now shift to Neutral like the the operators guide shows, cranks now? (a/t trans and no trans stated, so.... i guess away at what is there......
  6. does the starter relay close cranking, if not, work back from that and dont blame the starter, motor. fuse C1 runs this relay. is C1 good. or FL1 or FL2 fuse blows,
  7. ill now show the schematic (wild guessing engine and transmission..!!!)
this is the cranking path, (good starter and battery and cables)
the top of the drawing is the main power 12v feed from FL1 and FL2 fuses. (mains)
then you turn the switch to start
and 12v goes to fuse C1. got that?
then to the a/t box PRNDL switch. and in park or neutral
the 12vcc passes (10 to 12.6) cranking, or more if starter dead.
goes to the starer relay. the relay closes. does it?
if not it will never ever crank the starter.
if you have manual trans, the part in ? below is a clutch switch (pedaL )

NO ANTIHEIFT OPTION.
the bottom of the coil in starter relay is grounded. full time.
if you have antitheft option the Antitheift module makes up that ground. if happy.
so if the pin 5 on relay is 12vdc(dead relay) then the IMMO is unhappy. good luck fixing that.....

if IMMO not happy,
we then try both keys, lost your spare?
oops.....

one voltmeter and 15min work , or 10 less if IMMO lamp glows or flashes.
does it?
my post assumes, all things can fail, lacking, good input on dash lamps....

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.

Where is the start relay on a 96 Geo prism I can find it


wont crank? Check fuses first? (USA answers)
use the scan tool and get P1500" starter signal dead?
which engine, 1.6L or 1.8L which trans, A/T or M/T (auto./stick)
did you try cranking in Neutral (guessing A/T)??
the relay with 2 white wires, it is.
the USA left drivers side fuse box. is WHERE it is.
if you hot wire the starter and it cranks its, ok the starter
if car cranks in Neutral the PRNDL switch is bad.
if the relay below has 12vdc on coil or 11v, cranking
voltmeter across coil and output contact is dead the relay is bad.
if no 12v across , that means bad key line (PNRLD) or bad ignition switch, (hot wired starter works, is base line 1st test)

Van will not crank over, seems to have no power to the starter


Battery? If OK, turn the ignition switch to START and listen for a click indicating the starter relay is closing. If it clicks, the starter may have failed. If no click, check 10A CRANK fuse 8 in the instrument panel fuse block. If OK, check 40A IGN-A fuse in the underhood fuse/relay center. If OK, check for 12V at the top of the IGN-A fuse. If OK, the ignition switch, the park/neutral position switch (shift quadrant), or the starter itself are the only other possibilities

My 2006 buick lacrosse wont start radio and lights work but its not saying nothing when i try to crank it


Hello! Do you hear a click when the key is turned?...If no click is heard either the ignition key, the Crank relay, the starter, or the battery are suspect...Having lights and radio does not mean the battery is capable of running a starter motor......Put a meter on the battery...should read 12.5 volts...Turn key...Does voltage drop to 8 or 9 volts? Bad battery...If all is well with battery and connections to it...Check the starter fuse # 33 in the under hood fuse/relay box...If the fuse is good that click you should hear is from the Crank Relay in that box...If all of the above is OK connect your meter to the Purple wire that is connected to the starter motor...When the key is turned 12 volts must be on that wire...If there is the starter motor is defective...So, #1...Do you hear a click when key is turned...That would point at a bad starter or weak battery...#2...If you do not hear a click bad fuse #33, bad Crank Relay, bad ignition switch...#3...If fuse is good Bad Crank Relay or Ignition switch; Crank Relay is a low cost item ($10)...Replace Relay...Stop there and send a comment as to results...Guru...saailer

My 99 Gmc jimmy will not start. the fuel pump is good the fuel filter is not clogged, i replaced the neutral safety switch, plugged in my code reader no codes, i believe it is the starter or the ignition...


Does it crank or not? If no crank then look at the starter or ignition switch. If crank but no start then look at the ignition system. Check for spark at the plugs and also check the fuel pressure. If there is spark try spraying a little starting fluid into the intake. See if it starts and stays running. If it stays running reply back and I will explain why.

I'm not getting power to starter, battery is ok, starter is ok. what could it be?


The hot wire to the starter comes from the starter relay. The relay has for pins numbered 30,85,86 87. 30 should have power at all times, this will put power to 87 when the relay is energized Now 85 is usually ground and 86 is the ignition wire. The ignition wire will be hot when you turn the key to the start position. Also in the fuse box the is a crank fuse 10amp. you will need to check this. You have one fuse/relay box under the hood and one under the back seat. I believe the fuse you are hunting for is under the seat. The seats come out one of two ways. first you has to push back on the front of the seat while pulling up where the passenger sits on both sides. Yours may have a latch on both side same place. check this out and let me knowIf you think the relay may be bad, just swap it with another one in the relay box. Of course replace it if it is.Randy
