I have an 86 6 cycider engine s-10 blazer, when I first got it one of the fuel injectors was bad but the other was working and I was getting gas but still would not start, after replacing the furl injectors along with the throttle body and still would not start so I tracked it back to the fuel pump and replaced that as well however I killed the battery, after jumping it it still didn't work so I ulled out the battery and recharged it over night. Now every time I turn the key ver it doesn't seem like I am getting fuel and at the same time after turning the key once the battery seems to die but after unconnecting the battery and hooking t up again all the lights come on but the same thing happens I turn the key it all goes died. Any suggestions?

First have the battery tested,to make sure its good. Or use a known good battery.clean all cables and connections. After its spinning good. Spray some carb cleaner into the air intake,and see if it starts,if it does it will die as soon as the carb cleaner is burned up confirming a fuel problem. Have you checked for spark at the plugs? Also what about the fuel filter ?

I was actually going to check the fuel filter to day along with the fuse but got side tracked so I still have to do that and ill check the spark plugs again, anything else if this does not work?

Need to confirm what's not there,spark or fuel. And go from there. Also check more than one plug for spark check a couple.
