Fixed passlock now no fuel, 99 blazer Lt 4wd
Really confused,I fixed the passlock issue but now the fuel pump will not run,I don't think it would just go out but the truck has sit awhile, thought said just changing the pressure sensor I have an extra one on hand, this is my project truck and it ran till I had to change the switch, that made me have to fix the passlock now the security light is out but the fuel pump isn't running. Any help at all will be very appreciated thank you

The two are not related. A passlock fault defeats the fuel injectors but leaves the fuel pump alone.
Lets get your fuel pump circuit fixed. Get a voltmeter on the fuel pump priming tab in the fuse box and see if you get 12V for a couple of seconds at key on.

Does this model have one of those "rollover" switches that is supposed to kill the fuel pump in case of a serious accident? I have heard of people accidentally tripping it while doing electrical work of various kinds. It's a simple reset button.
