2002 Express 2500 No fuel pressure new fuel pump and filter
Does anyone know what else I can do? I have a 2002 Express 2500 van with a 5.0/305 engine. I recently experienced starting problems and determined the fuel pump wasn't working properly so I replaced it and it seemed to work fine, at least for one day. Now on day 2 it is doing the exact same thing; not working.

I have heard stories about aftermarket pump failing or being faulty. Especially if you put the old fuel back in, or loosened some sediment in the tank during the reinstall.....
If you have power at the pump when you turn on the key, and you dont hear it cycle, then try the rubber mallet to the underside of the tank....if that works, the pump is faulty.

I put the new pump in and then drove it about 150 miles and all was fine. When I got home and turned it off and then tried to restart it it was acting just like the old pump so I'm thinking it wasn't a pump problem to begin with. I was reading in another post about a Hot Fuel Module but it was a later model van. Do you know if my van would have one of these and where it would be located if it does? There is no mention of an HFM in the owners manual. The fuses look good and the relay "clicks" when the key is turned on.

If the relay clicks, but no run at the pump, then you need to get in there and get a test light at the pump. If you key on, and the test light goes on a few seconds then goes out......the pump isnt working.
There should be a 3-5 second run to prime the system at key on.....
not sure about fuel module.
The fuel system on the new vans with the Ls engines is very different
