W140 S500 Cannot start when HOT
I have this W140 S500 Its cannot be start when its hot.
Car starts fine and revs like a beast when it was started cold.
There is a mere hesitation during accelerate from 1000rpm to 2500rpm.
There is fuel pressure standing means that the regulator is working. (cold start no problem)
There is spark firing from the spark plugs when i pulled the HT cable out and tested it.
So far replaced-
1/Camshaft Sensor
2/All high tension cables
3/All spark plugs
4/Fuel pump relay
5/Electronic throttle actuator
Not yet replaced-
1/Crankshaft sensor
2/Ignition coil
3/Ignition control box
4/Both fuel pump
5/Air mass flow sensor
6/Distributor rotor
7/Distributor cap
