Has anyone seen a situation when VEMS sends signal to fuel pump relay chaotic? It had to turn pump on for 3 seconds, when ignition is turned on. Now, when I leave it on "on" stage, it turns pump on for 0.2 sec, turns it of for 0.2 seconds and that patern randomly continues until I turn ignition key off.

It has been running well for a few years, could settings just.. fly away?
