I have a gx liberty with a wrx motor box and diff running a wolf 3d v4 computer
It had been running fine and then sat for afew months and now wont start It has fuel but no spark any idears where to start looking?[Obviously i know nothing about wolf computers]

Check the unit for ignition trigger signal either by ;

One of the lights on side of unit(not sure which one...download manual and rtm)
Check if cranking rpm is registering on hand controller or laptop.

Then if you don`t have trigger work out why !(broken crank or cam angle sensor...wiring et)

If you have trigger registering ;

Check ign output is active(lights on unit I think or laptop display).
Check for injector pulse(lights on unit or handcontroller or laptop showing inj pulse ms whilse cranking.....)

Test ignitor if all of the above is working but no spark is happening.

If it is firing injectors whilst cranking it obviously has a trigger and rpm is registering....so its likely wiring, ignitor or fault with wolf3d ignition output channel/s

OS

The small black box near the engine speed should disappear when cranking.
If it does the crank angle sensor is fine. Does the fuel light come on?
