Just bought an 88 blazer, guy said hes positive the fuel pump went, filled up the tank, brought it home, and now all it does is crank.put a new fuel pump relay in it, no luck. I really dont want to siphon the gas out and drop the tank, so is it possible to put an external fuel pump on it?? please help me quick!!

 

A little more vehicle would be helpful. I'm guessing that this is a 5.7L TBI and you should be able to buy an aftermarket in line electric pump at a parts jobber. You just have to make sure that the pump will deliver the proper pressure. I believe that would be 10 to 12psi.
