My van was running fine till i went over bumps can this affect my fuel fillter in the tank

You need to inspect the undercarriage but it is my guess you jammed the fuel tank into the electric fuel pump screen.

be checking the fuel filter.. and the auto shutoff relay..

the ground fell off of the fuel pump or the plug came loose. its between the tank and frame. pull the wires down until u see the connector. unplug clean and plug in. I would check the fuse and relay first. usually there is another relay that is the same as the fuel pump in fuse box. switch them and see if it works

Did you change the fuel filter? changing pump stirs up sludge in tank, and a clogged filter puts stress on pump and can cause failure.

You might have a defective fuel tank pressure sensor!

First try and change the fuel filter. this also happened on a van i worked on. I cahnged the filter and it runs fine now.

some of these vans don't have a seviceable fuel filter. you can check with a local parts store to see if they list one. if they do then it is located above the fuel tank.

Hello. They are located in the fuel tanks. I say tanks plural because it's a 350 Club. There is also a pressurized pump on the frame rail just to the inside of the frame, just about under the driver's seat, if it is equipped with dual tanks. It's a rare occasion that one cannot run the van without prior notice of a tank mounted pump going bad. I'd try the fuel interrupter switch located in the passenger's side kick panel before anything else. Push the button top to reset it and then try starting the van. If the vehicle has suffered a jolt, large pot hole, bump etc...

its located inside fuel tank

you first step is to confirm the van has fuel pressure when the problem occurs sometimes fuel pumps only fail at certain conditions there maybe debris in the tank being stirred up when she fills please rate -jeff
