Hi guys,
My beloved Chimaera seems to have developed a problem when trying to start when hot!
It has the hot start kit fitted.
When trying to start hot the engine spins over as fast as normal ,fuel pump kicks in ,but wont fire for about 15-20 seconds then with a bit more throttle it coughs and sputters then fires up!
Drives perfectly once running ,starts from cold instantly.
Any Ideas?

Thanks for that Alun.
Coil and amp were new chnged when i bought the car 5 years and 7000 miles so I think it may be worth getting new ones to eliminate them,the problem is where can you get units that you can trust, ever since the Chinese bought the Lucas brand name you can trust lucas units.
If I remember correctly the new units i bought were from a Landrover specialist ,i might try them again.
Are Bosch any good or any other ideas?
Car was serviced by Matt smith 500 miles ago,plugs were checked .cleaned and gapped Matt said they were 100% (NGK Iridiums).
Will pull one out later1

So an Update!

New parts arrived,all genuine parts ,Bosch Coil, Magneti merrelli amp, Land rover branded Dizzy cap and rotor.

Replaced Cap and rotor first, evidence of arcing on one terminal where lead fits into, no signs of damage on rotor.

Then fitted coil and Amp ,note no transfer grease on amp ,new unit fitted with transfer compound .

Went for a nip around the block (31 Miles) engine much smoother and pulled better from low down in higher gears.

Once home left it for 15 minutes tried to start it and it fired up as quick as when its cold .

Tried it an hour later and started just as quick.

Thanks for the advice as always lads !

I am now going to book a visit to Jools for a 14CUX tune up session.
