  • IT could be a fuel pump, but cold be other fuel or electrical problems. Why did they need to be replaced before ? What were the symptoms ? You need to check the fuel pressure & flow before replacing it. Check with what the specs are.
  • with in that year for GM there fule pumps go out and i have 176000 miles on this I bought a new fule pump from advance auto and they told me that even theres go out fast that is why they only carry a one year replacement on it well i have had 2 go out in less than a year so i talked to them and asked to upgrade me at no charge and they agreed they are giving me a Bosch. one of the best you can get I also talked with my grand dad that retired for gm and he told me that delco which is made for GM was sold out cuase there stuff was becoming crap and advised me not to put delco on the blazer for that is what was on there from the start. So i would have to say the reason that is went out is cause of GM not making the correct stuff to stand up to there name
