Check the thin wire connector on the starter is OK, this connects to the key ignition switch. Run a lead from the + on the battery (just touch it, don't keep it on) to the big wire on the starter to see if it spins.
The starter is connected directly to the battery with nothing in between - the thin wire closes the solenoid when it gets the signal.

I'd first of all check out the plcuk site - all you need there TBH.
Quickly though:
Batteries are in parallel - the second is for cold weather/heavy duty starting..... or get a truck battery in there - as long as it gets enough amps jobs a good 'un.
There'll be a diag connector plug under the dash (glove compartment IIRC) - this is where you'll need an analogue multimeter - needle sweeps will give you a diag. Set meter to 12 or 15V
Plug has middle 'blanked out' - if this solid section is at top - connect +ve of tester to top right pin, -ve to bottom left..... needle will sweep up n down.
Continuous fast means no diag issues and all is well.....
Slow (1 or 2) then fast sweeps indicate error - e.g. 1slow 4 fast is TPS.
There's a list of error codes on 4X4wire.com but I'm at work and can't get that one for some reason.
Check codes - clean/swap whatever you need to and disconnect battery while you make a cuppa - reconnect and check fast weeps only - means errors cleared..... try starting again.
If problems persist - check error codes again - see if something is fubar'd.
I'm back in Sunderland Xmas for a week or two - can lend a hand if you like (although I'm no diesel bod!).
PM me your number and I'll shout as soon as I arrive UK side.

Many thanks for that, will get a multimeter and see what i can find. I have also been told that it could be the glowplug relay (don't know how to test that though) and also i need to pull out the choke, but cant find one

No need to pull out the choke on these. Never needed to in over ten years with any of mine.
Glow plug relay is a good starting point. I'm not too sure how useful John's info will be because it sounds like the details for a Shogun/Pajero....possibly one with an ECU which L300's don't have. We only have an ECU for the glow plug system, the rest is all 'manual'.

Some basic info I wrote a few years back about L300 glow plug circuits. Pt1: There are actually 3 different types of glow plug control system on L300's! Maybe best if you establish which one you have before I go firing too much data at you..... There are two common types: Auto Glow System and Super Quick Glow System (We'll ignore the Self-Regulating Glow System for now!) Slide the drivers seat forward and remove the service hatch, now look in the area above the air filter pipe and see if you can identify your system from this image:  |

Many thanks Bruce, will do that when my dad gets back home (he has the key for the garage)

You'll have to understand that I wrote all this out to help someone else out the other side of the Atlantic, so forgive the way it's written. I'm going to assume for now that yours is the more commonly found Super Quick Glow circuit?
Pt2:
If it is the Super Quick Glow system that you want to check, let me know because I can lay my hands on pretty much all the diagnostic data for checking the function of the whole system! (I can get the data for all the systems, but narrowing it down to the type of system that is faulty is helpful before I go posting TOOO much info! :lol: )
I can get detailed info on the following parts of the system:
:arrow: Pin allocation and full diagnostic checklist for the complete Glow Control Unit
:arrow: Information and diagrams on checking the Water Temp Sensor
:arrow: Inspection diagrams and checks of the Starter Relay
:arrow: Diagrams & info on checking 'Dropping' Resistor (Super Quick system only)
:arrow: Full diagnostic checks of both Glow Plug Relays
Let me know where to start and I'll get on with posting the info up here (it'll take some time though, so please be patient! :? )

Pt3: Right, After MUCH work trying to turn it into something you can actually make sense of from a really bad paper copy, I have finally cracked it!!  It's a bit too small to make out in this size, so HERE is a better sized image of the complete wiring diagram for the Super Quick Glow System I have not put it up as a direct image link because might be a bit large for some monitors! If you want a much bigger 2,500 x 2000 pixel version (just in case you want to print out in hi-res??) then CLICK HERE Hope that is a start?? I'll get to work on the other parts of the system when I get time! Maybe not today I'm afraid (The next bits will be all the diagnostic checklists for every wire/pin in the main glow-plug circuit....) I've digitized, edited and labelled all the drawings, it's just the 'fun' part of typing in all the data now! Watch this space...... P.S. PLEASE NOTE - the 'IGI' shown in the diagram by the ignition switch should actually be 'IG1'!! This is more obvious when comparing the diagram to the diagnostic checklist that I will post up later.... It was a VERY poor copy of the wiring diagram and it was only when producing the dignostic list did I notice that it is a '1', not an 'I'! Sorry about that! |

Pt4: .....and here is the diagnostic info for the Glow Control Unit: The unit can be found inside the 'B' Pillar to the right of the drivers shoulder (just above the access hatch for the air filter etc...)  The diagram below shows the pin configuration of the harness plug for the control unit.  I have written up all the diagnostic information associated with this unit (took me a few minutes I can tell you!) but it doesn't translate too well without keeping it in a table, so have uploaded it as a Word document with all the table intact as well as screen-grabbing the document to make the image below:  You can download the Word document HERE - I hope it makes sense?? I really have run out of time for today, so I'll have to cover the 'water temp sensor', the 'starter relay', the 'dropping resistor' and 'glow plug relays' tomorrow if I get chance....sorry about that! (it's taking me a LOT longer to do than I had thought!) Hope it is of some help for now?? Regards, Bruce. |

Pt5: (the last bit  ) Right - this last lot should help you locate a potential problem! Tie this little lot in with the chart above and double check against the wiring diagram and you may well get a result! I FULLY agree with MardyDelica that you shouldn't attempt wiring diagnostics unless you know what you are up to (it sounds like you do though!) I'd hate to think of you burning out the glow control unit or melting any wiring in the loom! (maybe this is more a warning to others?? Please don't take it the wrong way!) Here we go: Diagnostics for the GLOW PLUG RELAYS:  Diagnostics for the WATER TEMP SENSOR:  Diagnostics for the STARTER RELAY:  Diagnostics for the DROPPING RESISTOR:  I have uploaded all the diagnostic info listed above onto my webspace for you to download. This is a single Word document with all the four diagnostic tests listed above (I just split them from the document for here so that I could place them next to each diagram....) Please don't be too harsh about my spelling! HERE is the document to make the complete check of the glow system along with the larger one for the Glow Control Unit HERE which is also linked in one of the posts above (just in case you missed it!) It took me a while to produce, so just kept the layout as simple as possible... Best of luck diagnosing the problem - I hope you get it sorted?? Regards for now, Bruce. |

As Bruce has pointed out (and the plug diag shows) the plug is in act wired differently - my bad.......... sorry about that.
That lot should help though! If stuck still by the time I get back - I'll head over. We can see what we can do.
