Push pump I have a 1995 6.5 diesel. I have put on a new push pump but I'm not getting any power. The relay and the fuses are getting power. I need to know what gives the push pump power?

The pump relay gets power from two different fuses, then the engine computer grounds the relay to send power to the pump. Fuse 4 is hot all the time and fuse 9 is only hot when the key switch is on.
What part of the equation is not happening ?

firstly remove the fuel pump from the tank and test it by connecting the leads from the pump to a 12 volt battery....if the pump turns on then test the wires running from the pump to the front of vehicle.....since you have replaced the relay then that is not the issue also some vehicles have two sets of fuse blocks instead of the standard one ......does the pump spin up at all when you turn your key to the first position without starting the engine? if it does then you need to test the fuel pressure getting to the intake....i replaced a pump recently that was only pushing 8psi to the engine instead of the needed 52-66psi new pump fixed the whole issue

What size engine ? gas or diesel ? Did you check fuel pump inertia switch for being tripped ?

The primary (coils) side of the fuel pump relay is powered by the CRANK fuse (10 Amp) located in the instrument panel fuse block. This fuse is hot ONLY when the ignition switch is in the CRANK position. The secondary (contact) side of the relay is powered by the ECM-B fuse (20 Amp) which is hot at all times. This fuse is located in the engine compartment fuse block. The electric fuel pump in the tank only operates during engine cranking.

You can usually go by the wire colors. The fuel pump relay wires are pink, gray, black, and green with a white stripe. When troubleshooting a fuel pump that is not coming on, the relay is the best place to figure out why. You can pull the relay out and put a jumper wire from the battery to the terminal with the gray wire. If the pump runs, you know that isn't the problem. Then turn the key on and use a jumper between the terminals with the pink and gray wires. If this turns the pump on, you know the ignition switch is sending power to the relay, and the fuse is good. Pull that jumper out, but leave the key on. Push the relay back into the socket, but put a jumper from a ground point to the terminal with the black wire. If that turns the pump on, the ground wire is bad. If not, the PCM is not turning the relay on. Reasons for that may be a bad wire from the PCM, a passlock issue, or the PCM fuse/power wire.

look in the truck

Check the fuel pump relay.
Check the fuel pump auto shutoff switch, push RED reset button.

What you need to do is drop the fuel tank and put a new fuel pump in it. I would drain the gas and put new gas in after you get the pump changed.

probe elect. circuit of pump must be some damaged wires along the way

Hi. There is a fuel pump relay and a fuse in fuse block. Check both.
