my blazer has multi problem it quit on me one night.  the next day i tried
to find out what the problem was. i changed the distrib. cap with rotor
button, marduel, ign. coil, knock, map, throttle, and idle sensor.  i
notice something the fuel pump wasn't on. so i change it, but it still
dosent come on with the ing. switch. so i ran a junction wire to see wil
it come on. it did, but the blazer still would not crank. it would sputter
like it want to start, then just turn over. mind you plenty fire comming
through the system. is their any other problem other than what i have done
that i have missed.  what could it be.  some one help me please???????????
