Looking for my Volvo 240 friends around town

Portland OR

Description

My lovely 240 Volvo is down due to a melodic clicking sound from the fuel pump relay (which I made sure was good still). I had it towed to my mechanic a month ago and worked on (for this issue) but it came back. Anyone do any test light diaging and can help? Last thing that helped was a pin or two to the ECM was cleaned up and that helped. After getting it back, it stalled while I was on the road and somehow I bumped a wire in the engine bay and it cleared up for the ride home. Probably something shorting out but any suggestions on how to help would be great! Ive done some searching online and haven't found a issue like this. Maybe this is just under the general electrical issues area but don't know. Oh used cars.. Here is the vid of the symptom https://youtu.be/GDF-k1FSXUI
