guys just did a ecu check got code 22 but its not listed plz help because zed wont start cheerz.

You sure you didnt miscount lol

 

LED codes for MODE II:

 

11: crank angle sensor circuit

12*: air flow meter circuit

13*: engine coolant temp. sensor circuit

14*: vehicle speed sensor circuit

21: ignition signal circuit

26*: boost pressure sensor

31*: ECU

32*: EGR function

33*: exhaust gas sensor circuit (left)

34: detonation sensor circuit

35*: exhaust gas temp. sensor circuit

42: fuel temp. sensor circuit

43*: throttle position sensor circuit

45*: injector leak

51*: injector circuit

53*: exhaust gas sensor circuit (right)

54: signal circuit from A/T control to ECU

55: NO malfunctions in the above

Maybe you need a proper cable to check the codes and carry out a full diagnostic check on your vehicle.

22 could be the fuel pump :-

apprently code 22 is fuel pump,but when i turn ignition can hear pump prime and it doesn't keep on buzzing deffo code 22, 2 short flashs 2 long= 22 have checked every possible thing and all seems fine, would the ecu give a false code ??

Check this link out below when Van was having similar problems, links contained within to show how to test to see if pumps have failed or something else enroute to them.
