Hi all, I have a 1kzte in a kzn130 surf (‘94 auto) but I’m fairly certain 90 series share the same engine. If not and this is in the wrong section I do apologise.
I have had my truck off the road for nearly a year now trying to get it to run but nothing has succeed…yet.
The issue is that the spv is not getting its signal to let the diesel go through to the injectors. I have done the following:
Replaced the ignition barrel plug
Checked and bridged the spv relay, checked the EDC relay
Sent the ECU away to be professionally reconditioned
Checked all fuel sensors are working and within ohms as per fsm
Replaced spv
Replaced all pump loom wires from the engine bay
The truck runs, but very rough, when the RB wire from spv is earthed
Truck doesn’t run when 12v applied (briefly) to timing control valve
Checked the timing belt and everything lines up
Both wires to the spv plug have +12v
I noticed the wires to the fuel temp sensor on the pump were cracked so replaced them, then the truck decided to run fine for a day. Went back the next day and it was back to its old tricks.
I’m really running out of ideas here, hence posting about a surf in a land cruiser forum, so if anyone has any ideas, please let me know.
