Let me preface this with some additional vehicle information. 2018 Roxor (maybe 30k miles but who knows…), only mods are a stage one chip tune and blinker kit, with a couple of issue that I don’t believe to be related:
-Power steering isn’t working. I already know this is due to a blown compression fitting on one of the hoses. Probably a result of putting bigger tires on it.
-Gauge cluster doesn’t work. Common problem, she ran fine without it for years.

Now to the main event. My vehicle will start and while in neutral. I have no issues revving the engine. If I place the vehicle in 1st gear I can operate it at very low speed. If I attempt to move it over 5mph(?), the engine suddenly dies.

I’m not seeing any codes, and I don’t have a fuel pressure reading. Anyone else seen this issue?

So I picked up a VEEPEAK and OBD2 harness so I could check my fuel pressure. Everything looked good. So I ran code scanner and…

P1641

Raw code: 1641

ECU: Engine control unit

Status: Pending fault present, Pending fault present during this driving cycle

OBDII: Fuel Pump Primary Circuit Failure

So I believe I’ve found the problem. I’ll follow up once I replace the fuel pump.
