HELP.... 90 turning but not fireing??

[BigA]

went out to my 90 2.5TD this morning, not used it since Friday, and it wont start? turning over OK, white smoke coming from exhaust as usual, but just wont fire.

quarter of a tank of diesel, checked fuel getting to filter, and draining from their OK, fitted new starter a couple of weeks ago, so turning over OK?

flattened battery, not sure about the battery anyway, but been starting OK up until now (positive terminal hot when i removed it, melted the vaseline?) now on charge.

Any suggestions greatly welcomed??

Have you bled the system?  Air in the fuel system will make it a hard time for the diesel engine to fire up.

IM SURE YOU COULD RULE OUT THE BATTERY IF ITS TURNING OVER

no just looking that one up, been some time since i had to do it? but will give it a go, once the battery is charged again?

fingers crossed :oops:

I've read on some other forums, on certain diesel fuel pumps, you can have the problem of air leaking in if the engine isn't run for a few days.  But if the vehicle is used almost daily, the amount of air that leaks in is barely going to make a differane on start up.

i generally use it every day, just SWMBO had me doing other stuff this weekend, so out with her. I made the mistake of mentioning that the 90 was running well at the moment about a week ago, so i should not be surprised it has packed up.

The fuel pump was replaced about 6 months ago, i gave it a pump earlier, their was no pressure at all, don't think that is right?

bye the time the battery is re-charged will be dark, so i will have the added fun of trying to bleed in the dark.

oh i love my Landy  :?

simple thing, but have you tried using the heater plugs for 15 seconds before u start it.. my mates TD wont start if he doesnt use them.. and it just sits there making white smoke!

The smoke coming from the exhaust should mean that there is diesel getting into the cylinders, so ur stop solenoid should be working

[BigA]

OK, i bled the diesel system, checked solenoid, whilst it was off i thought hey ho, lets replace it (after all i have replaced about everything else   ), put battery back on, and after some serious winding it started  :P

now...... took it for a quick spin.... a bit jumpy at start, so thought, yep, probably air in fuel?, blockage? something like that, but soon settled down to usual, smoothish drive. Parked up, tried starting a few times and all OK.

left it for about an hour, and just on the curious side went out and tried it again, few seconds on the heater plugs, and started (best since i have owned it). Turned off a few times and restarted, all it seems was ok?? then switched off, took key out, and it was still running?? put key back in and switched on and off again, and it stopped. after further testing it did this a couple of more times????

what is going on  :?:  :?

Sounds like something is wrong with the electrical side of the ignition.

It could be running on oil...if you cut the fuel off it burn sump oil, would do this if its a very worn engine.

this is my next investigation, and one that i hope to be able to fix?

this i hope isn't the problem

Steel, diesel's don't have an electrical side to the igntion.... a diesel is a CI engine... Combustion Ignition - works by fuel being compacted/compressed rather than the fuel being ignited by a spark.

Also means that any Land Rover diesel (bar the TD5) is very, very easy to hotwire!!!! - even if fitted with an immobiliser!!!!


The only electrical thing is the fuel stop solenoid...
Usually a sign of faliure if engine does not turn off when the key is removed.

If it does this again then remove the wire with the engine running - should stop straight away.

Might also be a dodgy connection on the back of the ignition barrel.

If the Landy refuses to start again.....

Try running a wire straight from the fuel solenoid to the battery and try again - would highlight/isolate any possible problem with the wiring... if it starts then problem possibly found.... if it doesn't keep looking.

There are lots of other possible causes too....
(will post tomorrow as off to bed now - sorry)

Thanks for all help, and in future i will make sure i take note of peoples suggestions more  :oops:

Merry Christmas to you all.
