My 350GT cranks strong but fails to start at the moment. I have replaced a number of parts recently: Knock Sensor, Spark Plugs, Ignition Coils, Crankshaft Position Senor, Camshaft Position Sensors x 2 and the Fuel Injectors too!
I'm thinking that my issue may be related to the Fuel Pump. I have checked the relay and fuses and they seem to be ok. What I find is that when the ignition is switched to the on position, you can hear the fuel pump prime once per session. That is to say when you attempt to start the car it works once only. To hear the fuel pump prime again, you would have to switch off the engine and remove the key and reinsert if that makes sense?
Is that expected behaviour, or should it prime each attempt at starting the car?
