Hey all. So I’ve been having an issue where I can’t get my clubman to start. I know it’s fuel related. Im getting codes p3158, 3152, 3149, and 3155 all being high pressure fuel injector hush side circuit low. I’m at a loss. I’ve changed the hpfp, injectors, fuel rail sensor, but not the low pressure fuel pump. Before I did this I wanted to see what all of you think. Everything is hooked up and has been cleaned. I can disconnect the battery for a bit and the car will start right up but kill after a while. What could it be!?!?!? Thanks for the help

 

P3149 MINI Code - Cylinder 1 High-Pressure Fuel Injector High Side Circuit Low
P3152 MINI Code - Cylinder 2 High-Pressure Fuel Injector High Side Circuit Low
P3155 MINI Code - Cylinder 3 High-Pressure Fuel Injector High Side Circuit Low
P3158 MINI Code - Cylinder 4 High-Pressure Fuel Injector High Side Circuit Low

You need to check the wiring harness on the fuel injectors; the ECU is seeing a poor connection from injectors.
Check for cracked wiring, poor grounding locations, or short-to-ground issues.

I tried all of that Erik. Connections are fine and no bad grounds especially with a newer harness. I needed one anyways. As I’ve changed things it’s actually improved but the ghost is still there. I’m going to try the sending unit next bc it acts like there is air in the fuel system to me. Sometimes it runs great and others I can’t get the car to fire especially on a hill. It almost acts like it’s starving fuel but after a few tries can get it to fire back up. The next thing I’m going to have to do is check lines and make sure nothing is kinked and thats pretty much everything besides seeing if the DME is faulty.
