my big tuurbo esc cos is breaking my balls, it defies to run rite for me. symtoms are, struggles to start when it does (sometimes it will start perfect ) it runs fine until you rev it above 4000rpm then it dies like it's not getting enough fuel or maybe too much but anyhow here is what we have eliminated:- swapped ecu's, coolant sensor, charge air sensor,phase sensor, crank sensor,map sensor, lamda sensor. can anyone help me cause this is really getting me down

lancia delta 6 times WRC

I would also substitute plugs, leads, dizzy cap, coil and if that doent cure it look into a loom problem?

Could it be the Fusebox playing up?

Could be fusebox or the main loom multi plugs under the pass' side bonnet vent - they corrode and give wrong signals to the ECU - worth checking as they're both very common issues with the EsCos.

Could also be any of the associated wiring for the sensors......


Good luck with it.

Also worth checking the fuel pump relay (make sure it is seated OK)
