There is a slim possiblilty that the fuel-pump or connector tube is going bad..particularly if you have a single tankHi All,
So I changed a freeze plug, t-stat, and did a radiator flush on my sons 85 K10 Silverado, has the 5.7 tbi. Now it is harder to start in the morning. I used the 50/50 antifreeze mix. Its only low 50's in the morning here. Any ideas?
