So I have a 98 Blazer currently. Everything was going good, but then I had to replace fuel pump. Worked well for a while, but now it stutters when accelerating, has check engine light (blinking sometimes) and is hard to start. Friend tells me the engine is misfiring. So my question is, I hear of alot of fuel spider problems and things... these were common in the late nineties? Will a 2004 Blazer run into similar problems? Or did they get those issues all worked out?
