Thread: 3.9 not starting when cold

Hi Guys,

Same Rangie, got to the end of the running issues but still have an issue with cold starting.

If it has not been run for a couple of hours, it can take up to 3 mins of cranking for it to start and then runs like crap for a few seconds and then if perfect.

After that, it starts after about 1 1/2 cranks.

I've just changed the coil, ign module, dizzy cap, adjusted the MAF and throttle body and TPS to spec and set the timing to 10deg (running better than at 9deg).

I will go and have a look at it again when I can and measure voltage drop at the coil when cranking but he has this problem at 6am leaving for work and lives 45min from me so I'm not going there to check it then.

I't does start rough when I first get there but I was associating that with the rest of it's problems which it seems is not the case as it runs as good if not better now than most Rangies/Disco's that I've driven.

Cheers Casper.

having similar problems.
disco starting/earth

i have to crank sometime almost till it has no battery and sometimes i have to move the throttle.if i adjust the AFM it starts first hit but misfires on the road.

not thought about the fuel temp as it doesnt do much on other brands and is mostly used for hot starting.
