both digital odommeter

the 98 is one of the very first discovery 2's

both vehicles are identical

 

Ok, I was thinking you might have had the engine in the wrong truck being the DI and DII used different engines.
The crank sensor is a common fail item on the Bosch engine, its a cheap part to rule out, looking at the engine from the front, right side, 3o'clock position on the back of the engine.
I would also check the fuel pressure at the fuel rail to make sure it is getting enough fuel.
If you are not sure of the shops work then I would go back and double check their work.
Start with the simple and easy stuff, you are not loosing coolant are you?

 

no coolant loss

they swapped the crank sensor from the pare discovery, however, i guess tht is not to say either are working properly, but the swap made no difference.

I don't think the fuel pressure has been checked

I guess a pressure test / compression test on the engine just to be sure too

 

I also think that would be a good idea to do a compression check.
Start with the simple free stuff, then the cheap stuff and work your way up from there.

 

I think you're dead on ***** Spike
Start over with the basics and eliminate them first.
Plug wires are easy to mix up on the coil packs make sure they are correctly installed.
Crank sensors when they fail cause the engine to stop running.
If they installed it improperly, then it's "possible" to not run right.
Make sure they installed the crank sensor correctly. The sensor should be installed first
(flush against the mounting plate on the engine block) then there should be 2 sleeves
(about 13mm long) then the nuts that hold it on. If the sleeves are installed first before the sensor it's not correct.
It's also easy to roll the intake gasket when installing the intake manifold and create a huge vacuum leak on 1 or more cylinders (I've done it myself). Easy test is to pressurize the intake system and listen for leaks.
You can also use propane or carb cleaner around the manifold but it's hard to do because of the upper plenum.
Disconnect the torque converter bolts (as spike suggested)just to be sure.
Report back and we'll work from This point on if necessary
Don't sweat it You'll get it sorted.

Cheers

 

Hey guys,

i have been working all week, so have not had a chance to respond.

I will give a detailed response this weekend, which may help others hopefully.

Your advices were greatfully received.

I received a surprise call today saying my disco was ready, i nearly fell off my chair!

it is running, a little lumpy on gas so could do with a gas service asap

it is quite rapid, and will tootle along at about 1200 revs doing 40mph

it was dark when i collected it, and i only drive it home as it has no tax, but with a bit of luck and a service, i might be up n running

i will give a bit more detail regarding the cause and cure later

many, many thanks

 

Please keep us posted!!
