I have a blazer with a 4.3. It will not start it just will turn over like the fuel pump is not working. But the dash indicator lights are not working either. Everything else electrically are fine. It is not a fuse because it did this before but then started later. Now it wont start. Can anyone help here? Thank you

 

Check and make sure that the bolts going into the battery are tight.

Is it the original Delco battery? 'cus those are notorious for sucking.
