Morning all

Its a 2wd turns over starts runs for approx 3 seconds then stops.
As soon as you touch the throttle it dies so it wont rev up either.
try to re-start it and it does.

Things i have checked so far;

Cap,rotor arm,leads,coil,ignition pad,injectors,spark plugs,TPS,lugs on crankshaft sensor and sensor gap and all the wiring back to the ecu to make sure there isn't a broken wire.

Any suggestions??

Thanks in advance
