I, i would like to have the wirring diagram of a gmc 1500 95 6.5 td for the fuel pump.

My fuel pump do not have 12v for work and the solenoide of them do not click when put key at on!

Thanks for the wirring!
 
It probably your Oil Pressure Switch. It's located behind the fuel filter and is known to go bad. Replace it and all shoould be well. You might want to try applying 12v to the pump just to make sure the pump isn't dead.

I jump the pump and she work, but how could we be sure that is the oil pressure who are defect? Do they have test to do on it?

Thanks!
 
The fuel pump is driven through the oil pressure sender (OPS). If the OPS is defective then there is no power to the fuel pump.

By the way, Welcome to the sight

Yes, you can jump a wire between the two outside contacts on the oil pressure sender harness, if the pump runs then it is your OPS
