97 s-10 blazer fuel pump

[DoubleDeezy]

i just changed my fuel pump in my 97 s-10 blazer and it still won't start

i have heard there might be a fuel pump reset switch but no one knows where is there one? if so where can i find it?

is there anything else that might be wrong?

Can you here the fuel pump turn on when the ignition key is turned on ? not sure about a reset but there is a shrader valve ( similar to a tire valve stem) on the fuel rail near the top center of the motor back by the fire wall. A gauge can connect there to measure fuel pressure. There usually is a black protective cap on there to keep dirt out. You can press the center pin in ( just like the center pin on a tire valve to let air out ) and gas should squirt out. Of course this is flamable so cold engine, engine off, key off and protect the eyes, it should not just dribble out there should be a good squirt. It will not keep coming out because the fuel pump is not running with the key off and once the system pressure is relieved it will not squirt anymore.

I know this sounds kinda elementary, but make sure you have gas in the tank. I made a mistake when I replaced my fuel pump on my 86 Blazer. I just KNEW there was a problem because I replaced the pump and put gas in it. I had put the pump in upside down, and it was sucking air from the top of the tank instead of gas from the bottom. Also, make sure the distributor is sending the signal to deliver fuel.
