On my 2001 gmc sonoma truck it will not start with pouring a little gas in the carb . And then runs good .it has a new fuel pump .

checked fuses , #9 fuse for fuel pump was loose.

basic trouble shooting time... check that there is spark and move on to the fuel system if there is... possibly poured to much gas down and it's flooded.

P.S. if that is an old engine with lots of miles on it and you poured too much gas down the carb you may want to check your oil... raw gas may have leaked down into the oil pan as well

Take off your gas cap and have someone stand there with thier ear at the hole, (no smoking), turn the key to on just before start and they should hear the fuel pump humming. if they dont then try to start. if it doesnt start turn key off and at that instant the pump should be heard again. What i think is happening is your pump is not energizing . Its supposed to energize when turning your key on and off. This can be caused by a bad fuel pump or pump relay switch. Hope this helps. please rate me

Have you checked for fuel in the fuel rail? If so have you checked the injectors. If the problem is located in the injectors then there are two possible problems:
1...All of your injectors are clogged. Highly unlikely but possible.
2...Your computer is not sending a injector cycle command to the injector. This could be caused by a faulty cam position sensor or a faulty computer.

you say you replaced the fuse, but does the fuse have power? the gray wire at pump should have power when cranking, or for 2 seconds when turning key on. At fuel pump relay, put power onto gray wire, the pump should run if the wiring is good. if it doenst run then ck for power at fuse while power is on gray wire.
