So I just got everything buttoned up on my engine replacement, and I go to turn the key and the starter will click and I get solid flashers on the dash. I've never seen this happen and haven't found anything on the forums yet. If you reply ASAP that would be amazing.

 

This will sound kind of silly, but have you checked that the battery is still good? Many years ago when I was doing some car work I would listen to the car radio and this drained the battery just enough to make it not quite start. LOL

 

Yes I have, even charged the battery, did contact a friend who is used to S10's and when you dont have enough grounds, it'll flip on the flashers to a solid state.

 

There should be about four sets of grounds on the back of the heads - easy to miss ....
