Thought the fuel pump went, replaced it, then found out the relay wasnt clicking. Replaced it with a tested one, but still doesnt work.

this may be a fuse box problem see if grn wire is sending power to fuel pump relay and check ground as well. if power is going to fuel pump you might want to put some dielectric grease on prongs and tweek them just a tad. so it makes better contact also check ecm b fuse
