Problems starting my land rover 6.2 v8


Recommended Posts

Hi Guys,

Can anyone give me a hand here, I have a land rover 90 fitted with a 6.2 v8 gmc engine. It had been running no problems for over a year, then one day it would not start on its own, only when I gave it a spray with easy start.

Once it is warm it will start all day long, but as soon as it gets cold again it will not start

I have changed all the plugs and checked the injector pump and it does pump fuel through but I'm not sure how much it should use.

I have also had the starter overhauled.

I have taken it to a few garages and nobody seems to know anything about these engines and end up just giving it back to me as they do not know what is wrong.

A friend says it can not be the injector pump as if that was not working properly then the land rover could not run at all, he says it could well be low on compression and to get that tested?

If you guys think this is true do you know what psi i should be looking for in every cylinder?

Any help would be great as I'm stuck here.

Thanks

Have you checked to make sure the heaters plugs are actually working?.

We had one that wouldn't start when it was HOT! The compression increased as it warmed up and the starter couldn't turn the engine fast enough.

I would still suspect the starter, we have given up with reconditioned ones as they don't work well, maybe the electricians can't get the right bits.

We also had a reconditoned injector pump that didn't work properly until re-reconditoned by an expert. And we've had problems with lifters that stick and even problems that seem to come and go for no real reason. Having stripped and rebuilt two of them I would reckon that they are badly made rubbish. I wouldn't have one myself.
