Scratching my head here chaps.
As above my 4.6 is starting but cuts out after a second or so, it doesn't cough & splutter it just dies as though you've turned the ignition off.
When you turn the ignition on you here the fuel pump hum for a second or so & the PWM valve click under the bonnet.
Engine starts & I have a constant 12v supply to the EDIS module & to the ECU (these are constant & aren't dropping off)
Fuel pump keeps running until a second or two after the engine dies.
TPS has been calibrated, engine is showing RPM, air temperature & coolant temperature.
Any ideas?
