Doosan (& Daewoo) G25P-5:
No start

I have a machine that we replaced the engine in and first startup engine sounded ok but had no throttle response, took machine to dealer here in dallas was told to replace trim valves ,throttle pedal, electronic throttle body,and fuel lock off solenoid , after replacing all parts with new ones still won't start and I don't seem to be getting any signs of propane from the hose going to the new mixer. I'm about to pull my hair out with this POS , any body have any suggestions? Thanks

The rectangular connector on the throttle body will give issues, also i've expierenced wiring breakage inside the wiring loom, the place where the wiring loom crosses the transmission. Plus signal for lp lock comes from fuse box, minus signal for the lp lock comes from ecu, chances are that the plus is missing due a broken wire. Good luck!

.
Check the oil pressure sending unit by the oil filter. Clarks have the same engine and these go out a lot. Also you need to clear all codes and idle relearn on the second screen of the laptop.
