My 1995 R.R 2.5DSE is reluctant to start when hot. It's fine when cold, glo-plug lights come on, starts first time. However when the engine is hot, the glo-plug lights do not come on and it takes an awful lot of engine cranking before it fires up.
The motor was fine until it went in for air con servicing, ever since it then it won't start easily when hot.
The dealer has checked all the engine temp sensors, fitted a non return valve in the fuel line, fitted an larger capacity battery. Still it is reluctant to start when hot. Any ideas/help gratefully accepted.
