My 98 4 door S10 blazer will not start, it just cranks. For a while the idle would feel a little weak and at times when I would give it some gas it would lag on the power, my wife claims that the blazer has even stalled on her a few times while making a turn. It got to the point where it would not fire right up, it would crank and crank before eventually starting up. Now it just doesn't start up, just cranks.

Friends and family have suggested that it may need a tune up or that the ignition module may be bad. Also I have read that it may be a fuel pump or some other fuel delivery problem. Im hoping there is a way I can find out what's wrong with it without going down the expensive road of replacing parts that didn't need to be replaced in the first place!

Any help will be greatly appreciated!
