My 1999 ford expedition fuel pump is not working,can this cause by not being able to get any ignition>

Hey Joe, are you sure the cam moved? The cam is usually held in place by tension placed by the lifters/push rods/rocker arms/valve springs.. Check to see if the cam sprocket will only bolt up in one position, if so, you should be able to time everything... MAKE SURE ITS RIGHT - 300% RIGHT - BEFORE you reassemble...

No fuel - fuel pump failing or fuse to the pump open, fuel safety cut off / inertia switch has been operated (in a collision recently?), ignition electrics trouble (no spark at plug), computer issues..

SOUNDS LIKE YOUR FUEL PUMP PICK UP TUBE HAS A PIN HOLE IN ITWHICH IS CAUSING IT TO SUCK AIR. MAY HAVE TO REPLACE FUEL PUMP.

This sounds like a bad fuel pump , this is very common. you will need to drop gas tank to install new pump.

Here is the normal fuel pump pressures for the 2000 Ford Expedition with the 5.4L SOHC Vin L >>

Key ON Engine OFF (KOEO) 35-45 psi Key ON Engine Running (KOER) 28-45 psi

Here are your pressures if this is the 4.6L SOHC >>

Key ON Engine OFF (KOEO) 30-45 psi

Hope this helps with your concern...

Here is the manual
FUEL PUMP SHUT-OFF SWITCH After a collision, if the engine cranks but does not start, the fuel pump shut-off switch may have been activated. The "Fuel Reset" indicator light will illuminate in the instrument cluster. The shut-off switch is a device intended to stop the electric fuel pump when your vehicle has been involved in a substantial jolt. 1. Turn the ignition to the OFF position. 2. Check the fuel system for leaks. 3. If no fuel leak is apparent, reset the fuel pump shut-off switch by pushing in the reset button. 4. Turn the ignition to the ON position. Pause for a few seconds and return the key to the OFF position. 5. Make a further check for leaks in the fuel system.
The fuel pump shut-off switch is located in the passenger's foot well, behind the kick panel.

OK, there are fuses on the driver's side down below.

But, if you are having a fuel pump problem, it's likely that the fuse is alright and you need to replace the fuel pump. Same thing happened to our 1999 Ford Expedition Eddie Bauer Edition. It quit working. And the inertia fuel cutoff switch didn't help, either (flipping or pushing it).

So, if you have no fuel coming, it may very well be the fuel pump.

We changed ours around 112000mi.

replace the fuel pump

Replace fuel filter if it has not been done in a while. Also check fuel pump pressure with a gauge and compare with spec. When key is turned "on" the computer turns on fuel pump via relay. If the computer does not see rpm signal (engine start) within approx. 2 seconds it turns the fuel pump back off. Cycling the key often helps to build up fuel pressure sufficient to start when filter is plugged or pump pressure is weak.
