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???????????

you can test the fuel pump by locating the test port, a single wire on the drivers side between the brake master cyl. & the fender, if you need I can probably find out what color the wire is. you should put a 10 amp fuse from the battery + term. to the test port, the pump should run for just a few seconds. If so, check the fuel pump relay pins & sockets, relay cost is about 13 bucks but get the right one. On mine I found a burned Hot on the relay socket.

let me know how you come out.
