I have a 93 blazer 4.3 cpi and it wont start i have replaced the fuel pump, i have done the filter, i have redone the spider and yet all i get is still turnover after turnover, it has sat for 3 years but ran before it was parked..if anyone has a clue what to do and where to start please let me know...

 

What brand of fuel pump did you use? and have you replaced the fuel pressure regulator?

 

the standard one from auto zone and yes i did replace the fuel pressure regulator...

 

Do a search on the board for a fuel pressure test. These trucks really only like 2 pumps, Ac-delco and Delphi.

 

It could be a few things, are you getting a check engine light?

richphotos, do you have a part number for the ac delco fuel pump?

 

Have you checked for spark ???????

Have you done a fuel pressure test ?
