Posts: 339 | Where you been hiding michael?  
Maybe stale fuel or a shit batch of fuel mate,chuck a bottle of metho in the tank n see how you go,chances are if your rigs been sittn round for awhile,then stale fuel, you may have a bit of moisture in the tank from it.shit fuel is shit fuel,drain n refill or add metho,may come good.
Also,where the ECU is,check the plugs that go to the ECU dont have moisture or has'nt popped a wire out the harness or a wire may not be sitting right on the termnial.give that a go

Posts: 241 | nah mate she just had a full motor rebuild new head new gear box and a rebuilt t3 with high flow bearings.
compression test was normal with no variations between cylinders as i thought 5 or 6 ex valve was worn but the motor is in good order more so electrical timing.
i think its the crank angle sensor but the auto elec wont test it because he said the car would not run if it was that
anyone know how to test a cas appart from diagnostic mode on the ecu? got me fucked
