hi ,i own a 2000 blazer 4dr,4x4, i bought the truck(suv)for my wife 3yrs ago it had 90,000 on the clock, i really love the truck,but ive had nothing but trouble since we bought it.first was the radiator,changed that,then the transmission,rebuilt that(amco),then the ball joints,changed them twice going to be three times soon,water pump,fuel pump,then the intake manifold gasket went had that fixed. brakes 3 times(front),did the rotars,complete tune up,and now im having trouble starting it after it sits over night,after its running,itll start up fine. ive changed the fuel filter,tried seafoam,i got that from a post on here,but no change,i am so frustrated,i love the truck but im at a loss,so if there is any body thats had the same trouble,i would appreciate your input, thanx in advance

 

If you have the 4.3l vortec engine check the fuel pressure with the keyswitch turned on but not running. On my 96 if it is below 60 psi it is hard to start. I could pour a little gas into the throttle body intake and it would start and run fine. Replacing the fuel pump was the solution.
