Well I started the Jackaroo for the first time yesterday after replacing the cracked head. Also fitted new glowplugs, timing belt kit (Dayco), thermostat and water pump. I pre-filled the oil rail and it came to life on the fourth turn of the key!
Blew a bit of smoke as expected but idled really lumpily and drove even worse. No power and running rough as guts.
Checked MIL codes this morning and I'm getting 15-Fuel temp sensor lo/hi voltage and
51-Injector #1 circuit fault.
So I assume the problem with the #1 injector circuit should explain the rough idling and running if its only running on 3 pots, not sure what the implications of the fuel temp sensor would be.
Ah, the fun of owning a Jackaroo!!!
