So last night I was sitting in my 01 Expy on a fairly declined slope (facing downward) when suddenly my car died after a few minutes. I took out my OBD reader and saw that there was a new small EVAP leak code. So I checked the gas cap, and notice that the cap was fairly loose. So I thought "okay I'll buy a new one soon". But what caused my engine to die? Not by a small vapor leak, right? That's when I decided to put the truck in neutral and park on a more level surface. Vehicle started right up. The fuel pump was no longer sucking the fuel in on the slope is what I gathered. I replicated the issue just to make sure, and then ran the truck on level surface for about 10 minutes without any issues. Drove about an hour after that without it dieing on me.
Another thing.. earlier that day, my gas gauge took a long time go up when I put gas in the vehicle. My tank appeared to be almost half way full. I put 6 gallons in and expected the gauge to rise immediately. Instead, it took long to finally get to where I guess it should have been. Not sure if this is related, but thought I'd throw it in.
Do our Expys die if they're at too much of a slope, due to poor tank design or something? Thanks.
