Which fuel pump to buy???
91 S10 Blazer 4x4 4.3 V6 TBI
I believe I am having fuel pressure problems. My truck stutters when I get on the gas and it is hard to start on cold mornings. I have to turn the key on and off 6 or 7 times to build up enough pressure to start. Anyway, I was looking at fuel pumps on NAPA website and they have several types. One rated at 14psi ($42) ,one rated at 26psi ($53) and one rated at 65psi ($92). Now I read in one of these forums that I need around 60psi for cold starts. So why do they sell the weaker pumps? I guess I need the more expensive one right?

A TBI motor only requires 8-10psi at the injectors. Napa's website does not give the option for a Z-code engine which is what the TBI motor is.

Whichever one you choose, one bit of advice...don't scrimp because of price, the cheapest isn't always the best. For the effort it takes to change one out, go for the name brand and you'll save some headaches down the road. speaking from experience.
