Having problems with your 2000 Chevrolet 3500 ?
Cube van won't start
\015 Have confirmed there is no power to the fuel pump. Did this by interrupting wire going to fuel pump and checking voltage - none. The gas guage reads way past full when ignition is on. Lately engine cranked longer to start. Prior to this it was a quick starting motor. Any connection?Engine cranks normally. Does not start. Thank you for any help.\015
Possibly,could be a bad ignition switch,find a wiring diagram for the fuel pump power wire after the ignition switch,up around the steering column.Turn the switch to Run position,check there to see if a 12 volt supply is present,from there,it should go to the relay,that sends power back to the pumpYou can also check power at the fusebox with a test light on both blade ports of the fuel pump circuit to see if any power is present on either blade.
Ok then your problem is eletrical, you said you check the fuses, there should be a fuel pump relay under then panel in the hood. check that (if there isnt one then its a broken wire somewhere along the line to the pump. You can get the car started bo connecting the pump directly to the battery. There are 3 wires from the pump, 1 is hot the other is a ground and the other is for the fuel gage(float) just connect the hot directly to the battery and you should get startet. Warnin dont run it like this just use it to get to an autoeletrician
