No power to the fuel pump

I have a 97 f-350. The fuel pump is not coming on when I turn the key to run. I checked the wiring and was not getting power to the pump. I was wondering if anyone has a wiring schematic that shows that wiring. I checked the fuses and they all seem good. Does anyone know is there a power shut-off if the fuel system has pressure? I was going to bypass power straight to the pump to see if it's any good but want to make sure I have the right wire for power. I would really appreciate any help.

It sounds like a safety cut off. Have you had it up on a lift or done any work on it lately? Like stated alot of the Ford gas models have inertia switches. On my old Expedition it was located behind the passenger kick panel. I dunno if yours even has one nor if thats where its located but its somewhere to start until some of the more knowledgible guys are on. Good luck getting it back running.

Its a lift pump on the top center of the block.




The SD trucks have an electric fuel pump on the frame rail under the driver door.

Jarrod B unjless my research fails me the 97 has 2 pumps one is an electric lift pump that is on the frame rail that fills the bowl. The other is an injection pump which is what you have pictured. If someone could help me clear this up that would be great. I will scoot away with my tail between my legs if I am trying to get power to something that isn't a pump. Thanks.

NotStock The owners manual shows a shutoff but I can't find it anywhere. In looking thru the forums the general consensus is that was just for the 460. I called down to the local ford dealer and there supposed to be sending me a wiring schematic so we'll see.

They only shut off that pump has is the engine being turned off. Their is NO electric pump on a 84-97 Ford diesel unless someone added it. The 94.5-97 PS uses a two stage pump, a diaphram on the top pulls fuel from the tanks at 4-5 psi to fill the bowl and get filtered then it leaves the bowl into the second part of the pump which uses a piston to drive the fuel up to 55-65 PSI to fill the heads at which point fills the piston chamber of each injector and waits for the injector to be fired. There is no injection pump on a Power Stroke it has a high pressure oil pump mounted on the front timing cover. ALSO THE OWNERS MANUAL IS FOR GAS TRUCKS AS WELL ARE YOU READING THE DIESEL SUPPLEMENT GUIDE OR THE BLUE FORD BOOK??? Hope this helps
