I've been doing a lot of engine idle testing software changes on my idle ECU. I had run the tank down to 1/8 tank and this morning I could not keep the engine running after start. I tested a stock ECU and another ECU of mine with the old software and same problem. Added 5 gallons to tank and it ran fine.
So has anyone else seen this problem? It could be my level sender has gone bad and I was out of fuel. Or maybe my Tahoe fuel pump works like that.
I will have to investigate this problem later. I'm to busy working that software now. I wonder how my software testing results have failed because of that fuel problem.
