Customer Question
I found the injector...

I found the injector fuse on my 2008 envoy blown and since I didn't have a replacement I used the 20 amp marked LTR and replaced it.It cranked right up but now my transmission will not shift out of park with vehicle running

Mechanic's Assistant: Most vehicles have two fuse panels. Have you located both?

Nope just one under hood

Mechanic's Assistant: Are you fixing your Envoy yourself? What have you tried so far?

Just took LTR fuse and used it in the injector fuse location.I assumed LTR was the lighter fuse.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Just wondering if LTR means lighter

Hello, my name is***** will be helping you out! I have over thirteen years of experience in the automotive industry for numerous different makes & models. I enjoy doing what I do, it is my life.

Yes, but it also control the DLC (Data Link Connector) You can try disconnecting the battery and reconnecting it, its possible it went into limp mode when the injector fuse blowed. If the problem persists, then its possible the LTR fuse is making it limp mode since you no longer can communicate with the DLC

Let me know if this helps :).

I have no replacement fuse at this time.If I disconnect battery and reconnect will it reset or will I need LTR fuse all?
GMC Mechanic: Mike, Auto Mechanic replied 8 months ago

That is what I am trying to determine. It should reset and be fine, BUT if the DLC has no communication it could be possible you will need a fuse there.

If battery disconnect gives you the same issue, then it would be clear you will need a fuse for the DLC
