I'm not getting any power to my fuel pump from the key turning to the start position.

Hi,

First, check to make sure the ECM B fuse is good in the under-hood fuse box. In addition to checking the fuse, confirm there is power to and from it.

Here is a link you may find helpful:

If that is good, remove the fuel pump relay and switch it with a different one having the same part number to see if that helps.

If there isn't a different relay with the same part number, here is a link that explains how to test a relay and circuit:

Start with this and let me know the results.

Take care,

joe
