Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
What exactly do you mean by "turn over"? Some people actually mean engine starting but I refer to turning over as the starter turning the engine over.
Also, what engine is in this?
Ok, give me a minute to get the wiring diagram.
Ok, I have the starter wiring diagram. That STRTR fuse doesn't have voltage to it until the relay is activated.
Let me get the power dist wiring now.
Let's start by checking for voltage to the DLIS fuse #34 at the left side engine compartment. It feeds the ignition switch.
If that has no power (all the time) check the mega fuse 175a.
These are some real confusing wiring diagrams. I could look through them and ask you to check this fuse and that fuse. I have a better idea. Why not just check all of the fuses to begin with.
Here is the wiring diagram for the door locks though. look at all the fuses just for it.
Also, remove the starter relay and check for voltage in the socket. One spot should be hot all the time. If not, let me know.
I don't know which pin is #30. What about the starter relay socket test?
What about the starter relay socket test?
Oh, ok. Then the starter relay does have power. Ok, let me look at that diagram again.
Does the STRTR fuse have voltage when the key is turned to start?
I am going to assume it doesn't.
I think at this point you should retrieve the codes from the bcm and ecm.
Yes, OBDII. Do you have a scan tool or code reader or know of anyone with one?
Even before that. Is the security light remaining on? Ignition ON, view the security indicator. The security indicator should not remain illuminated after the vehicle bulb check has completed.
Yah, I have a code reader and it only retrieves the ecm/pcm codes and cannot get into the bcm. You will probably need a scan tool for that and they are expensive, the reason I don't have one.
This post should stay open for 7 days. Yes that scan tool should work.
Let me know hen you get your hands on that scan tool and if you don't know how to use it and retrieve the codes from both the bcm and ecm, let me know what model number Snap On scan tool it is.
