No spark and i can only get 5V at the coil.

Ok, first off your making this more of a mess than it is. The OP had the car running at some point and then it started having issues then dies. Hence no spark. I would not ever start with wiring. you run into messes just like this. Obviously he has a bad part in the system. He should have found the bad part first then clean up the wiring after. Now he has no clue what to do because he has disturbed all the wires. Start back a square one if possible and go from there. I am a aircraft electronics technician and do this stuff daily. People that go straight to wiring have no clue how to troubleshoot. eliminate the easy first then start shooting wires.


So looks like I was right. You never go to wiring first. You go to removable parts first. Fuses, reisitors caps etc.. Then if all is good you go to wiring not assbackwards. You usually just end up causing yourself more problems than you started with. Glad you found the bad ecu.
