February 26: Crank/No Start, 94708 . . .
Read MoreI started with the basics. Fuel pressure was within specs. I grabbed the scan tool to pull codes and didn't find any. The live data all seemed to be ok. I had spark, but it seemed to be weak. So I pulled a spark plug and found it wet. This is feasible - a weak spark may not make the plugs fire which would leave them wet. The curious thing was that the wetness didn't really smell like pure gasoline. So I took a fuel sample and found the source of my troubles.
The fuel that came out of the fuel rail was pink in color, which is definitely not right. Regular gasoline is yellow. But off-road diesel fuel is dyed red. But what is actually in the tank doesn't really matter at this point. The fuel tank has to come down and be completely drained.Once all of the old fuel was drained, I reinstalled the fuel tank and added 5 gallons of fresh gas. But before I could start the car, I needed to clear any remaining contaminated fuel from the fuel lines and rail. Using the fuel pressure test port on the fuel rail, I cycled the key several times and collected the fuel into an empty jug. It took a while, but I finally got all of the contaminated fuel out of the system.
