Just replaced the transmission solenoids on my 2010 hhr ls panel and now it wont start.

When ignition key is turned on dash lights up but the starter does not get signal.

 

You must have knocked a wire loose or connected some up wrong, maybe the PRNDL indicator on top of the trans got dislodged or uncalibrated.

 

We got it. I found another thread where someone had the same issue.

this was his fix and ours:
I figured it out!!! I didn't have the bolts that pull the wiring harness blocks up into the fuse spade terminals in the bottom of the fuse box tightened up enough. As I was tightening them they "Popped!!!" and I panicked and stopped thinking I was stripping the threads. After watching a video the guy mentioned this, and said to keep tightening the bolts about 10-15 more revolutions. Sure enough it pulled the wiring blocks up tight against the bottom of the fuse block and all my electrical issues went away and the car fired right up!!! Thanks for your help :)
I still have a trouble code but I'll post in another post.

 

Good you got the fuse box figured out! Thanks for the follow up!

 

Wow thank you so much, I had this happen to me this weekend. I ended taking it on and off 3 times to make sure everything was lined up and added dielectric grease to it also. I just went to ask why certain fuses had no power and other did.

Thanks again.
