Hi guys. I have a Zd30 2003 patrol and had issues for a while now. I had an engine light come on and was told after a computer diagnostic that it was the injector pump. I was also told that a reco pump would cost about 2500. I then went to a diesel mechanic and got them to check it but he said he wasn't getting a reading. He told me that he found a problem with the crank sensor after fixing one particular injector pump. So I replaced that in the hopes that it wasn't the injector pump. After checking things out and experimenting and searching I have come to the conclusion that it is the pump. In the mean time I have also started to have a slipping clutch. So I have pulled the motor out and now I need to figure out whether to replace clutch and pump and put it back in or replace it with a bigger motor, a 4.2. If I replace it is there a lot of extra work and cost involved with wiring and hoses? Will it bolt straight into the gearbox? Any advice would be greatly appreciated.
