Thread: 1998 3.9 discovery 1 is hard to start

If you turn it off and restart again straight away, does it start ok?

Ex's Disco had this trouble and ended up being a split in the fuel hose off the pump in tank causing pressure in the fuel rail to bleed down. No issues when running, only when left sit for more than 1/2 hour or so.

Turning ignition on and off several times made some difference when starting from cold, but not as much as I would have thought.

Could be the ignition module, search for Beeuteys posts on ignition module upgrade.

Thanks for the reply guys na it doesn't start straight away if I turn the ignition off after it's been running it takes a while to start again.
Thanks for that Ill check out now about the ignition module

Do any of you think it could be my spider unit the button doesn't work on the remote so I lock the car from the drivers door wich then locks all all other doors an activates the alarm when I unlock the red immobiliser lights all turn off but sometimes if it doesn't start ill get out the car re lock it then unlock it an it fires up straight away

It is possible, when mine went it was nothing at all not intermittent like some have advised. Not sure how to on a V8 but if you bypass the spider it will give you an indication if that is the culprit or not.

Yea right cheers I'll see how it all goes it's doin my head in.when I crank it over to start it it cranks for quite a while then sort of hesitates when it starts

It would be interesting to know what the issue is when you figure it out. I've got a 3.9 v8 '96 Discovery with the same issue and it used to only do it when it had sat for a while but it's starting to do it more often recently.

When it does start can you smell petrol &/or is there smoke from the exhaust like flooding?
