injector problems

[nigelvy]

I have a 2002 vt II that started to run bad running with miss it seems injectors not firing on #3 or #5
Spark at all plugs, leads and coil pack all good
I changed position of a suspect injector and it ran well so it seems to be electrical
But only on both 3 & 5
That’s as much info i have been able to work out
Would you have any more ideas?

any fault codes?
do a search on how to check fault codes on vt vx (by airstrike)

Could be PCM not giving signal out to the injector 3&5
Tests its signals from the PCM it will be giving out earth from the pcm.
Make sure the connection are clean. And check for fault codes.
