the service engine soon light is on and it keeps dying out on me i have had the blazer for 2 weeks and yesterday i put a full tank of gas in it and found out it was leaking so now im going to put a tank and fuel pump & filter in it tomorrow any tips??

 

What are the codes that are present? Get your self to your nearest Advanced Auto or Autozone and have the codes read. That light is telling you something.

*Moving to 2nd Gen Tech* - The 2nd Gen Tech section is for tech questions.

 

Gonna have to include more info, we aint mind readers.

motor, tranny, 2x/4x in your sig will help greatly in the future.

 

That SES light can be caused by LOTS of different things...one of which COULD be a bad gas cap....but get the codes pulled from Autozone or Advance Auto
