Hello Gabriel,

Did you replace the swirl pot and pump as an assembly?

If you can hear the pump run, I would say the pump could be running backwards, or you have swapped the lines by accident.

Pump is pumping to sending unit and return is OK but not going to engine.I I stalled new pump.Don't think its possible to swap lines.Different size lines.When I open lind from pump it pumps strong.

Do you mean the engine doesn't start?

Will it start on ether, starting fluid?

If so you have another issue, like security etc.

Have you scanned for codes?

Engine will start on fluid but does not receive fuel.Is it a fuel sensor problem or fuse.
Expert:  Gary replied 1 month ago.

Sounds like the injection is not functioning.

Have you scanned for codes yet?

Yes it could be a fuse, have you checked the fuseboxes for anything blown?
