I bought a farmtruck to pull tractors etc. the truck has a no start condition. I'm ok with small Diesel engines but this is my first diesel vehicle. I understand it is more complicated than my experience allows so I'm asking for help.
Truck has 167k. Original owner had new CPS, TURBO, VACCUM PUMP, FUEL PUMP, second owner had new IPR. After these installed, a conclusion was made that it has a bad hpop. Then I bought it. Second owner says. Fuel filter has good pressure, he checked fuses and relays, filters in tank sending unit are cleaned, and new batteries. He says that the original owner had a new turbo installed, put $40 in fuel in it, when tank was low, it died and hasn't started since. He also says that he pulled oil line from valve cover and put in a coke bottle to find oill "dripped out" instead of building pressure.
When I got it, batteries were dead, terminal connections were poor. I cleaned and charged batteries. I turned over engine, cranks quickly but no start. Very little to no white smoke, tach at 100 rpm, wts light works, no check engine light. I found that an obdii didn't connect and don't know of loaner and truck would be very tough to haul.
When I first cranked, wts light came on, then it did not, #22 fuse was blown. Replaced. Hasn't blown again. I do not disagree that hpop may be failed but it seems like there are a number of other possibilities as well. Was his coke bottle test any indication of hpop performance? It makes sense but I don't know all there is to know.
Yes I know a scan would likely be useful and I'm working on it but it's not an easy find. Also I have thoroughly searched/read forums but felt like I kept chasing rabbit trails without having my own... Thanks in advance for help!
