Hi guys - dads 2002 D22 ZD30DT non-commonrail Navara Di Coolant Water boil & Cranking via Starter Motor has ceases upon contact while under load ;
Coolant is boiling and overheating and returning back from Coolant Return Hose/Line (top hose) back into Radiator and over 'to' overflow bottle...
just tried sending 12V directly (in manual pulses as the thin wire we used is starting to get hot) to the spill (solenoid) valve and YEP! the motor is showing signs ofwanting to start - coughing and splattering etc...
Now for the tedious task of pump removal so we an check if it's the output...
Been rather busy and finally (dad) got a chance to remove and test glow plugs - 3/4 of which were apparently not working. Replaced the lot of them and STILL no go. Last thing to try now that everything's been put together is to try sending 12V directly to the spill valve while rest (pump/fuel...
Tested Glow Plug "System" and getting voltage to the plugs eliminating signal path incl. Relays. Measured the front plug (#1?) On its own and gave no resistance - while the other 3 glow plugs connected mutually via connection bracket read 1 Ohm in (in parallel).
Also tried heating intake plenum...
getting fuel to the pump "only" not to through the injector outlets - unless:
once we severed wires from between pump ECU & spill valve (solenoid?) and sent the spill valve 12V direct from battery and cranked her over - THEN she pumped fuel out of the injector outlets.
Again today tested...
After 2 days in garage my dad's 02 D22 ZD30DDT No Start.
It use to have symptoms of (difficult starts on cold mornings) and dad would kick start her in Reverse.
Tried usual suspects - getting fuel to return pipes but won't come out of injector outlets
until...
we severed fuel pump solenoid...
