Monster S4 '01 starting and fuel pump issues.

[waernes]

Okey, where to start.Last summer, my bike started shutting down on me while driving. It felt like i ran out of gas., other times i lost gas flow a couple of seconds. I thought that the issue came from the fuel pump-relay. After doing unnessesary things with the relays i went over the ECU connector cables. After using a spray to clean electronic connectors, blowing the connectors with a compressor it was good again.Now after a winter stored indoor, the bike wont run the fuel pump a couple of seconds when i turn the key to ON like it should do. Trying to start it without any fuel pressure is no point either. The fuel pump works, i tried it directly on the battery and it runs fine. I know the ECU connectors are problematic on the S4, but what can i do to solve it when my previous method dont work anymore.
