Hi all, I am back. Again, lol. This will be a bit of a longer read where there are multiple questions packaged into one.
Basic info:
109 74'
2,5NA (15J) no turbo
Std gearbox
I came back from holiday eager to drive the landrover again. However it did not start.
I checked the fuel pump, pumps fuel when cranking over. Heater plugs also worked like a charm. And which can be gathered from context: the engine cranks over just fine, nothing wrong with the starter.
Which already points me in the direction of:
- Its been 3 weeks so some stuff has corroded like hell
- A blown fuse
Otherwise, there really isnt much that can "break" all of a sudden.
However, that is where I get very confused and where my first sub-question arises: How can a diesel engine which does not need spark to fire; not fire when air and fuel are present in the cylinders and the engine cranks over beautifully? Petrol needs a spark, but diesel should fire up without this, right?
Anyways: (now disregarding fuel and air and going solely off of electricity) the thing is. My landrover is wired a bit differently, to the point where it has a safety type switch which must be flipped in order for the vehicle to start. I however do not understand how it works :/ (again ties into my subquestion, why does it need some form of electricity?)
If we take a look at the safety switch feature, all it does to my knowledge is from the fusebox short itsself to a part i cannot identify correctly. See picture.
the switch is a simple on off switch, which goes to the fusebox like this (fuse 1 blue wire)
what does this do? why does pulling a ground "work"?
Aside from this, judging from wiring schemes fuse 1 is all sorts of messed up, it should be all brown on one side and purple on the other. (tried this but to no avail).
So, update: magically it DID start. and ran well for about a kilometer, which is when i ended up stranded. Pulled everything apart on the side of the road. And put it back together. And just as magically it fired up. W H Y?! I dont understand what the blue wire does. And why it wont start without it.
Now it works again, but for how long. I dont mind finnicking on the side of the road. But i would like to understand WHAT im finnicking with.
All answers are greatly appreciated, thanks for taking the time to plough trough this long read.
Cheers
