Thread: No throttle pedal

the engine will start perfectly every time but mostly it has no throttle response at all. At these times the M&S lights will be on.
Turning the motor off and back on several time will eventually give a start WITH a responding loud pedal and no M&S flashing lights.
To me it seems to be electrical but I also hear the fuel pump quietly humming away. Discovery , I thought had me on the right path when he asked if I had been playing around with the injectors. I had just weeks ago, replaced an injector No 5, without replacing the washer or O ring.( I have since rectified this error.) I have also purged the fuel line twice. Once I have a proper pedal the car drive as it should and sometimes when ignition is turned off it will restart with correct throttle response. However if left for a while longer it will fail to proceed again.
Does this clarify thing at all?

You should have said that from the beginning, if it's about supply it has nothing to do with the throttle potentiometer but with the 5V supply from ECU to it which can be caused by a weak contact on that path somewhere or within the ECU, this can be very intermittent and unpredictable.... in this case set nanocom to inputs fuelling and watch the "accel supply" when the symptom occurs...if it's below 5V you have to make measurements with multimeter at the ECU output to see if it's from the ECU or in the wiring, or if you have a spare ECU try with that just for test no need to injector coding only to synk the immobiliser, or take a long thin wire and make a bridge between the ECU pin and TP bypassing that header i told you, it's the white/purple wire from ECU's C0658-14 to TP's C0787 pins B, J
