Re: computor not gronding
Does the problem with the fuel pump happen only on the car, or does the fuel pump LED not come on when you test the ECU on a Stimulator either?

Re: computor not gronding
Sounds like you've got some major wiring problems - and if English isn't your first language, following the wiring section of the manual may be a bit more challenging. Check to be sure the fuel pump relay is wired up correctly - my guess is it's not getting power at the right time.
