I really need some help starting my carone.

[VAN WILDE]

Hi every one.

I have a 1999 1.8 diesel ford courier.

It will not start sometimes, and sometimes it will.
The battery, the starter, the plugs, they are all fine. I have even been told to change the starter switch which i have,

It usually does not start when it has been used for around twenty minutes and it is warm. It wont even bump start. then as by magic, it just starts after been sat nearly an hour.

Any help would be greatly appreciated.

The banjo bolt in the return pipe on the injector pump has a little valve in it which bleeds air, if this valve sticks it wont start, Take the banjo out and check the valve rattles free if not give it a spray out with carb or brake cleaner to free it, normally stuck with small metal fragments from normal wear inside the pump. I think this banjo is meant to be changed every 80000 miles or suchlike on Ford service schedules.

No idea if this applies to Fords or even diesels, but IME not starting when warm = crank sensor.

if i disconnect the crank sensor should the car then fire up if that is the problem? thanks

I don't think so - it senses RPM and is thus pretty critical. Get a second opinion before pursuing that option though.

If the crank position sensor isn't connected or is defective then the ECU will think the engine isn't running. If the engine isn't running it doesn't need fuel so - other than cranking - nothing will happen.
If yours has one you could try fitting a new CPS & see if it cures the problem but getting the fault codes read would be a better idea as replacing parts at random tends to become very expensive & may not find the fault.
