Doodlebug · 2023-10-12 10:49:27

My 2004 scudo JTD blew a hose of the other day and I lost throttle I pulled over and found antifreeze all over my engine and thermostat hose had come off my van run fine prior to this no overheating I waited till it cooled down put the hose back on topped it up with water at the side of the road tried to start it it started and ticked over but it wouldn’t rev just wurring it ticked over for about an hour no overheating then cut out and wouldn’t start again had to get towed home during this it started a couple a times ran normal was revving normally then cut out and hasn’t started since I done diagnosis and changed throttle sensor and glow plug relay not showing any other faults now but still won’t start it fires when turning over then it don’t it’s intermittent
Please help

On one hand sounds like head gasket blown, on the other doesn't explain why it isn't starting again, as if immobiliser at work....??? Dunno.
ODB "testing" is nothing, barely ever shows anything but wrong diagnosis which commonly is failure in sensors etc...

I would suggest open a oil filler and leaving the cap on, see when you (or someone else) is cranking the engine over if oil cap stays in the place. If it just bobbles on the top- see else, but if it occasionally flies off- 100% head gasket.

the 1997cc HDI/JTD engine only need 3 sensors to make the engine start and run. these sensors are the crank position sensor, the cam position sensor, and the fuel rail pressure sensor.

everything else sensor wise can be unplugged from the engine and it will still run.

i would start unplugging things till it fires back up again starting with the mass air flow sensor just after the air box.

be aware that there's a thing these engines do when the timing belt is not in correct timing, if the cam and crank sensor are not within the correct marks it wont let the injectors fire
you can only see if the cam and crank are not in synchronisation by using live data diagnostics.

hope this helps in some way..
