fuel pump has no power 96 dodge ram 5.9l
the fuel pump 30amp fuse blew on this 5.9l gas dodge ram here.
when i looked at the fuel pump i see no power coming to the connector with the key on or key start. I swapped out the blown fuse and it good now. The fuel pump relay I swapped out too. I heard there might be a second fuse some where? Last edited by bratt; 04-12-2010 at 09:28 PM.

Re: fuel pump has no power 96 dodge ram 5.9l
I don't know of a 2nd fuse. The fuel pump only runs a few seconds with the keyswitch On unless the engine starts then it'll stay on. Are you checking the power at the fuel pump?

I might not have a good ground on my test light. I tested power at the fuel pump fuse and i saw power. I also saw power on one leg on the fuel pump relay. is there something I can do to test the connector to make sure the fuel pump is getting power before I buy another fuel pump?

Re: fuel pump has no power 96 dodge ram 5.9l
You might have an assistant turn the keyswitch on while you're holding your testlight on the positive wire on the connector. It should come on for a second. It needs to be the pump wire and not the fuel level sensor wire.

Re: fuel pump has no power 96 dodge ram 5.9l
Because a fuse was popped makes me wonder about a possible short between the relay and the pump. If the short was stout enough, it may have burned the wire in two or melted a wiring connector/splice, opening the circuit.
You might run a wire with an inline fuse from the battery to the fuel pump just to test if the pump will run...be careful.
