Howdo you know t starter is good?Is itnew or has it ben tested? If it has been tested than I assume the connectons are tight.
For the starter wiring diagrams, click here for early production and here for late. These files open with abode acrobat free reader.
Is his an automatic or manual trans?
First of all, check those fuses. Fuse #23 30A, fuse #12 50A in battery junction block and fuse #29 10A.
Or for the early model the fuse #4 5A.
4.0L AWD fuses ok
So, it's an automatic?
small wire to starter has no power with key cranking or in on position
Try holding the key on start and moving the shifter all the way from low to park. If at any spot the starter engages expect neutral or park, adjust the neutral switch.
did it nothing either
It may be the relay. Check for voltage to the relay at the light green/violet and the white/pink with key on start and in nutral or park.
ok hang on checking now
have power to lightgreen/violet but no power to white pink
Wthkey on start and in park or neutral?
sorry in on position
do i need to crank it
i mean start position
I thought yousaid it won't crank. Yes, with key on crank or start.
i mean do i need to put the key in crank position to test
ok doing it now
If no voltage there first double-check that fuse #4 5A or fuse #29 10A. Not just look at the fue but check with a 12 volt testlight or voltmeter. If the fuse is ok and still no voltage at the white/pink then check with key on start in park at red/light blue wire feeding the Digital transmission range (TR) sensor.
Now, if you do have voltage at the white/pink wire than the relay is most likely bad, but first ground the orange wire from relay to pcm and turn key to start and see if starter cranks.
have power to the white and pink wire
k, what did yu fi?
now iam going to ground that orange wire
Ok, te relay is probably bad, try jumping across if you can from the white/pink to orange or ground the orange.
whichever is easier
That should activate the relay
ok, when yo jump or gound that orange wire check for voltage at t yellow/light blue wire going to sarter
ok and just so you know i swapped that relay for one that i know is good
ok, check the yellow/light blue wire when you jump.
Ok, you have power to lightgreen/violet and have power to the white and pink wire with key on start, then you should have power to the yellow/light blue if the relay is good. What did you try about te orange wire? Did you jump it or ground it?
i have power to the light green/ violet and i have power to white/ pink i jumped it from white/pink to orange and still have nothing at the yellow/ light blue wire
and i tryed grounding that orange wire too
The relay is bad. Why did you think the relay was good?
I think it' bad. Take it back.
Is there anyway yu may have hooked it up wrong or backwards?
don't think so but will check it
i see a tech bulletin from 2006 about this same thing any chance that i have a bad wire
Like this. When you apply positive voltage to the white/pink terminal and ground the orange you should have continuity between the light green/violet and yellow/light blue terminals.
Did you test it or are you going with the assumption it's ok because it is new?
I just wanted to check the wiring to the starter, it's probably not starting because you are no using the key to start, thus the pcm doesn't know the key is on. Did you try it with the key on run when you jumped the starter?
Do you see any theft warnings or messages?
yes tryed it with key on still nothing when i jumped it at the relay did not really see any theft warnings any recommendations???
Let me get this straight, when you jump the relay from white/pink to orange you have no voltage at the yellow/light blue but when you jump the light/green violet to the light blue the starter works. Make sure you are getting a good ground on your tester and check it again. Just because the relay is new and it does click doesn't mean it is good.
