Hot start problems

What could be the likely cause of hot starting problems? The sierra's being a bit of a bitch to start if you dont let it cool right down. When it's could it starts first time without any problems.

Changed the plugs which doesnt seem to have helped

It's an old Ford. They all do that.

Yeah, you're probably right

Hmmm, think I need some new bait.

I get enough insults form the other half about it all the time, do you really think a lame one like that would upset me? :)

It is a pretty s**te engine at the end of the day (150bhp from 2.8 litres is laughable when compared to the same era Toyota it sits next too!), just thought there might be something obvious I havent thought of. Maybe adjusting the valve clearance will help, which I will get done when the new rocker cover gaskets turn up.

Rocker cover gaskets?

Pah! It's an old shed, you don't need gaskets. :-)

Heh, I was tempted but I was ordering some other things anyway, so for 1.50 each i thought I'd chuck a couple in anyway. Even went out and brought a set of feeler guages! That's dedication for you

Is it injected or carbed?

Presumably injected? in which case I cant tell you!

Yeah its injected. If it was carbed, I would have just put it down to that

Check the temperature sensors - if it thinks it's cold when it's actually hot, you'll have hot-start issues. Can't really think of anything else ?

Which engine?

If injected, it probably wouldn't run at all (apart from when cold) if the temp sensor was U/S.

One would assume the engine in the car with the hot start problem

So all Sierras used the same engine? You live and learn.

Nope, just that one ;)

It could well be. The 'security device' on the car is have the fuel pump wired into a seperate switch, and if you turn it on before you start cranking the engine will flood and wont start. But surely it would still have petrol sat in the cylinders when cold?

Unless of course it seaps past the rings as it all cools down. Hmmmm you could well have solved the mystery!

2.8i V6 Cologne thingy.

I think Burgerman may be on to something though. Might try and pick up some

2nd hand injectors from the scrappie!

Definitely needs the injectors overhauled or replaced. They shouldn't dribble at all. Remember when in use they're subject to plenum vacuum so will dribble even more.

I don't know that engine, but on the Rover V-8 EFI it's a fairly easy job to remove all the injectors then re-connect the fuel rails and see which ones are leaking.

And new ones from a specialist may not be an arm and a leg. Or check Ebay. You can also get them re-conditioned.
