Started the car this morning in -7 degrees celsius, gas pedal was working, however as soon as I went to pull out of the driveway the car had no power and stalled, I started it back up again and it immediately died and wouldn't stay idling. I started it up again and held the pedal to the floor, it stayed idling however the RPM wouldn't go above 1000 despite holding the pedal to the floor. I waited a minute and let go, and then the gas pedal had no response and was "dead". After like 3 minutes of idling it worked again, I drove it to my shop and it behaved perfectly normal. I got the new fuel pump in, looks like the old one was original - it had the whitish-yellow top, which would've been the same color as the rest of the pump, but the rest of the pump was covered in black what looks to be oil. I put some diesel kleen directly into the tank, replaced the gasket as well and filled it up with a full tank of fuel. Pedal worked fine the rest of the day, didn't seem to notice anything different when driving, however the new pump now makes and audible "splashing" noise when I turned the key. I checked the power to the harness before installing the pump just for the hell of it, don't have any measurements to compare it to, but I was seeing 10mV on one of the wires and 5mV on the other two, I put the ground lead on the brown wire. We'll see tomorrow if it's fixed the issue or not
