The last time it ran was May 10th and I try to start it every 3-4 months. Last time I tried to start it was a month ago and it cranked fine but didn't even seem to try to start. Want to get it running before the cold temperatures add another aspect to the problem and it will be over 80° the next few days. The glow plugs are working and the lift pump is pulsing. Those items and the controller were replaced a few years ago. I also put in this clear fuel line but don't remember what for.



I think it was to check fuel flow or air bubbles. Well the line has become dark and I can't see anything so I may have to replace it. What can I check in the meantime?
