The truck will crank but it won't start. Check the fuse already for the fuel pump. The fuel pump seems like it's humming only after you cut the key back off. It does not make a sound before you cut the key on. I'm not getting any pressure to blow off valve from under the hood. Where is the relay located and will it be anything else?

Hi,

According to the wiring schematic, it is in the under-hood intelligent power distribution module. See pic below.

I tried to find a legend for the IPDM but there isn't one listed in my manual. Take a look at that fuse box and let me know if you are able to locate it.

Take care,

Joe
