Have used OBD reader to see if I can diagnose problem and a fault has come up with ECU ( fault |1 ) I have recently changed the TPS as it was running eratic and struggled to idle ( over revving) that settled down and now I cant start it. Have checked for a spark which we have but think no fuel is getting through. Also sounds like a faint knocking from engine when it was running / engine under load. No sound when in neutral. Could it be crank position sensor? any pointers gratefully received thanks. glelly
