My 1992 rocky turbo diesel has developed a starting issue. The problem only happens when it sits overnight ( or perhaps cools down ) after I start it once it’s ok for the rest of the day ( I also live in Australia and it’s summer here ) . I have ruled out a fuel issues as there is no water when I drain it from the filter . I have also tried an old trick by spraying etha into the air cleaner box and she fires up straight away with ease, I think it’s a glow plug issue ..anyway , this is what my search has come up with.
I have changes glow plugs.
I have checked the power coming into the rail that power the plugs and it’s coming up zero on the meter
I have checked the current sensor and it’s showing about 8ohms and it also has continuity
I have replace the relay
I don’t think it’s the temp sensor as when the engine is cold, the relay clicks on and off many time as opposed to when it’s hot , it will click once ( maybe I’m wrong)
There is something called a pre-heat timer but I can’t find it.
Please help !
