Hello my name is ***** ***** I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required.

Expert:  TECHPRO49 replied 2 months ago.

Sounds like you just missed a main connector on that, and or ground cable, its going to something simple. And your prob looking right at it, this happens to me sometimes

Expert:  TECHPRO49 replied 2 months ago.

If you give me what power your missing I can find the ground locations and power inputs for that and send um your way

I fixed fuse box problem
Customer: replied 2 months ago.
But i still can only crank if jumping stater relay...and car wont start just crank
Expert:  TECHPRO49 replied 2 months ago.

Are you getting power on 86 pin on relay when turning over?

Expert:  TECHPRO49 replied 2 months ago.

If no power on that pin your not getting signal from ecm or bcm, maybe your ignition isnt sending signal to the bcm, I attached the diagram of the system,

Customer: replied 2 months ago.
With key in on position pin 86 has 11.7v
Customer: replied 2 months ago.
Actually i think its showing as ground
Expert:  TECHPRO49 replied 2 months ago.

How about ground on 85?

Customer: replied 2 months ago.
Customer: replied 2 months ago.
if i give it power thats how i get it to crank
Expert:  TECHPRO49 replied 2 months ago.

so you have a signal prob either the ign switch isnt communicating with the bcm or bcm to ecm or cem to relay, I would check ign switch to bcm first, nice power probe btw!

Customer: replied 2 months ago.
Tell me what to check and i will check
Expert:  TECHPRO49 replied 2 months ago.

on BCM backprobe this connector and check for voltage signal in start position on 2 and 4 pin, use a voltmeter and not the power probe, probe could throw ground and short out bcm

Customer: replied 2 months ago.
Idk if i told you, but sounds like no spark
Customer: replied 2 months ago.
You there
Expert:  TECHPRO49 replied 2 months ago.

yeah im here, I thought you got the spark fixed when you restored power?

Customer: replied 2 months ago.
No sir no spark
Expert:  TECHPRO49 replied 2 months ago.

how did the bcm test go?

Customer: replied 2 months ago.
Which connector is it there's five different ones
Expert:  TECHPRO49 replied 2 months ago.

the first one light green

Customer: replied 2 months ago.
4v both with key in on position
Expert:  TECHPRO49 replied 2 months ago.

so thats working good now we need to verify power and ground to bcm, ill be right back with that info

Customer: replied 2 months ago.
Ok
Expert:  TECHPRO49 replied 2 months ago.

ok so there are a bunch of checks for this ill send you all the pin outs and you will have to go to each one and verify power and ground in the schematics

Customer: replied 2 months ago.
Okk
Expert:  TECHPRO49 replied 2 months ago.
Customer: replied 2 months ago.
What color connectors is the one I'm testing and what pin number
Expert:  TECHPRO49 replied 2 months ago.

its labeled in the diagrams

Customer: replied 2 months ago.
All the powers and grounds are present as they should be
Expert:  TECHPRO49 replied 2 months ago.

then your bcm is bad and needs to be reprogrammed or replaced

Customer: replied 2 months ago.
I did notice there is an aftermarket car starter would that have anything to do with this issue?
Expert:  TECHPRO49 replied 2 months ago.

your getting all the signals to the bcm so it shouldnt interfere, I mean its solid testing

Customer: replied 2 months ago.
That aftermarket start cant put it self in security lock?
Expert:  TECHPRO49 replied 2 months ago.

what brand is it?

Customer: replied 2 months ago.
Cobra
Expert:  TECHPRO49 replied 2 months ago.

yes thoes could lock it out you can just remove it to rule out any lock out conditions

Customer: replied 2 months ago.
When you say remove it u just talking disconnect the connectors from the box
Customer: replied 2 months ago.
Like this
Expert:  TECHPRO49 replied 2 months ago.

no some of the wires are cut and spliced and only the controller would make the circuit complete, so trace down the wires and get everything back to stock

Customer: replied 2 months ago.
Lol ok, if you don't hear back from me in the next 20 minutes I will get back with you on Monday
Expert:  TECHPRO49 replied 2 months ago.

thats cool man, I figure this will take some time to diagnose,

Customer: replied 2 months ago.
Hey Jim pass lock relearn process would not help me with it though about the one where you put it in the on position for 10 minutes and do it three times
Expert:  TECHPRO49 replied 2 months ago.

interesting, if that procedure didnt do it you may have a immobilizer issue

Customer: replied 2 months ago.
I removed the aftermarket remote start but I still have the same thing going on I know it's something extremely small and something stupid that we are missing please help me figure this out so I can close this ticket
Customer: replied 2 months ago.
I also found this connector at the back of the BCM it was just hanging nothing connected to it and I tested it it is live it's got power and ground
Expert:  TECHPRO49 replied 2 months ago.

Im taking off for a couple of days ill have to open this up for the other techs to see if they can help

Customer: replied 2 months ago.
OK
