Which wire is the ground wire on fuel pump? - 2000 Chevrolet 3500

It is my understanding that the fuel lft pump has been replaced( updated) and is now gone back to the old way and is re installed in the tank.

I have had to put 3 lift pumps in since new, little did I know but Cummins tells me that the lift pump delivers minimal pressure and shortens the life of your injector pump.

So if that is true perhaps it is best to eliminate the lift pump and go with the new in tank pump. I plan on doing it the next time I have a problem.

YES THERE IS A FUEL PUMP FUSE IN THE FUSE PANEL. I THINK HE MAY HAVE JUMPED A HOT WIRE AND GROUNDED IT INSTEAD OF A GROUND WIRE. HOPE THIS HELPS. GOOD LUCK.

Diesel engines fire on compression alone (usually 400psi).The Truck may have air trapped in the fuel system.When you perform any fuel system repair on a diesel it is going to take alot of cranking to get the air out. You can take the breather loose and shoot a VERY small amount of starter fluid in the intake and it should start. Do not use starting fluid much as it can damage the engine. Good Luck.

It won't hurt to jump sire to drive, It is designed to pump all time when the engine is running. The only problem is the pump should not be on if engine is not running since it is designed that way to prevent a fire while pump continues on once engine is stops in a car accident. There is a control device to immobilize the fuel pump, if there is no speed sensor signal from the crankshaft. This needs to be located and fixed.
