I have an old Cat 12 Grader (S/N 71D438) it sat for about 3 months and now it won't start. There was only one good rain and while trying to figure out why it would not start, I opened the fuel injection panel, I noticed a bit of light rust. It starts and runs as long as I spray starting fluid into the air intake - I know that is not good for my engine but it helps to see what's going on... I removed the fuel injection pump top and fuel is coming out when the engine turns over.
So I think it's getting fuel. I suspect it has water in it though. Would that completely prevent it from starting? Should I just drain the tank, bleed the lines and start from scratch? (I guess it's worth it even with the price of fuel) And... how can I tell if there is moisture or water present in the fuel? I've heard of a way with a piece of paper or something like that but cannot recall how the test works.
Any help or ideas would be appreciated - a lot.
Thanks, Ol George.
