I have an '86 6.2L diesel Suburban that I converted to run on waste vegetable oil. This week I collected some oil from a restaurant, and the oil was contaminated with water! They left the lid off in the rain and I didn't stop pumping before the water was reached.
The truck died twice on the freeway, but I was able to get it started, and then it died again, more suddenly, I could tell it was different this time, and I culdn't get it started. I believe it was the water, although I also noticed that I had shut off the the fuel to the engine with a ball valve when I was trouble shooting earlier. But I think that a lack of fuel would just make it stall, not kill the pump.
Mechanical fuel pump checked out. I cracked one of the injectors lines and tried multiple times to crank the engine and no fuel came out. The Electrical connecitons are all good to the I.P. and supplying 12V. I am 90% certain that the injection pump is dead. Very small chance it is airlocked... but I've airlocked many times before and not had it be this bad. I will pull it soon.
I've found some rebuilds and new ones online and some on eBay and I'm wondering if someone has a good warantied source or if there is interchangability with newer 6.2L's or with 6.5L's? the recommended part number is DB2-4544.
Also any advice or resources for replacing would be great. I just ordered a couple books from thedieselpage products page so hopefully that will help too!
Thanks in advance!
