I recently rebuilt the top end of the engine on my Dodge Ram 1500 2wd V8 with the 318 in it and now it wont start. For some reason the fuel pump will not turn on but it was working fine before the rebuild. I check the fuel relay fuse and it seemed to be ok but i replaced it anyhow just to make sure. I have also check all my wiring underneath the hood just to make sure nothing got missed during the rebuild. So I'm not sure what else it could be. Any suggestions on solving this problem???
