HELP contaminated fuel (disaster?) $#%!&

[kerry]

I'm getting ready to leave for Santa Fe. Neighbor calls and tells me he has 5 gallons of diesel left over from a job at work, can he put in my tank. I say sure. He brings a yellow diesel container over and puts it in my tank. I drive 50 yds and car quits. %$#!*& It wasn't diesel and I have no idea what it was. Poured out the half cup or so of what was left in the container and it was thin and soapy, or at least bubbly. So now I have a tankful of who knows what and even when I try to run the engine on my diesel purge system it wont start. Neighbor swears he personally filled the container up with diesel at a fuel station. When I primed the system from the purge bottle tons of foamy stuff was coming out of the return line. Don't know if the IP is just filled with this foamy stuff and won't pump or if some other damage was done. The purge is moving thru the injection pump and back into the bottle when I prime it but not a hint of firing from the engine.
