hi everyone im having this little issue where every month or 2 my blazer will get a little moody and never start, it will turn over a literally run for about a sec then die. it will do this for awhile then ill leave it alone usually for about 20min then it will start right up and run perfectly fine for the next month or 2 when it will do it again, and the strange thing is is that it always seems to do it either after it rained or when its raining so i dont know if that has any part of it but i was thinking it was a fuel pump since mines already having issues with the sending unit thats messing up my gas gauge. if anyone has an idea what could be causing it please let me know cause it always does it at the worst times which its making it a unreliable car now.....

 

Could be the (Passlock) security system, could be a loss of ignition, could be lack of fuel pressure. Those are things to check when it acts up. Find out which one it is and post back.

 

Alright will do I got a new fuel pump cause that needs to be replaced as well to fix my fuel gauge issue but it may be awhile before I post back since this issue comes after a few months

 

AC Delco or Delphi only on the fuel pump Don't waste your time and money on aftermarket stuff.
