I was running biodiesel with no problems. Started blending WVO with diesel, didn't like the way it was running, parked the car for a few months and it wouldn't start. Flushed (pumped) out the fuel tank and put in straight diesel and replaced both fuel filters. Car started after a few tries, ran a little rough. Started her up a few more times over the next week with the same feeling a little hard to start. Then got busy and left her for a few weeks, when I try now there's nothing. It just turns over but will not fire. Any help would be greatly appreciated. I hope I didn't toast my injection pump.
