Boggs down in drive but not as bad in 1st 2nd and 3rd. Fuel pump is making noise

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Your Venture sounds like it’s struggling to, well, venture anywhere. If the **fuel pump is making noise**, that’s a red flag—it could be weak and not delivering enough pressure under load. Just because it starts fine doesn’t mean it’s supplying enough fuel at higher demands. A **fuel pressure test** would confirm that. The **throttle position sensor (TPS)** could also be a suspect, but without a scan tool, it’s hard to say. Since shifting into lower gears helps, it might even be a **transmission issue**—like a slipping torque converter or clogged filter. Given the wiring harness situation, I’d start with the fuel pump and go from there.
