It may not be a current problem. Have your fuel pump check by the dealer or the supplier where you bought if from. Another alternative is to make sure that the pump amperage requirement is the same as the relay amperage that it can support. For example if I have a pump unit that is rated up to 3Amperes, then if the power supply is being feed via relay that has 2Amperes rating. This setting may run properly for a while, but as the pump unit gets older, the amperage requirement is getting higher for normal operation.
Double check the amperage requirement for the fuel pump and replace the relay matching the amperage as suggested by the fuel pump manufacturer.
Replaced pump and filter. reassembled fuse block under hood, and as I hooked up the neg on battery, heard what sounded like spark on other side of hood and now have no power to ignition at all. Could be relay or fuse link?
