My car was a good running and driving car. Ik took out the wiring loom for painting. Today I built it back but the fuel pump doesn't run.

See image:

relais connection 30: gets 12v
relais connection 15: gets 12v switched
the green wire to the coil is tested and good

I can't find the problem. The car sparks so I asume the DITC stuff is all good. I have two fuel pump relais who worked before, so that can't be the problem. The fuel pump was also just new.

maybe the green-white wire to relais connection 1 is the problem, where should it go to ?

What about the overboost cutoff switch? I would eliminate it as a variable, and ground it out for now. If it is disconnected or the wire is broken where you can't see it, it cuts power to the fuel pump circuit.

Also, have you jumper the fuel pump relay to verify that the pump is running?
