We have a cx210 excavator and it now won’t start . We started it once by jumping lift pump relay power and moved it into shop to find relay power issue. But after cleaning,checking and fixing rubbed wires the whole harness we got power to lift pump relay . So we tryed starting it ,and it would roll and not fire . Then we tried either to see if it would fire and start , but it fired on either and seemed to not be getting fuel to motor.
Then we checked fuel filter and it was full and it sprayed out of injector lines when cranked. Then out of no where we lost power to that relay again ,so no power to lift pump.
it’s had electrical issues for years and still does as tech couldn’t fix that years ago. But it ran perfectly fine other then start stall start stall like 4 times until now.
So question #1 is what could cause the fuel to not be injected into the motor That was spraying out of loosened injection lines ?
Not enough lift pump pressure maybe ?
Question #2 is what could cause lift pump relay to loose power ?
Bad ecu?
