i replaced the fuel pump in my 97 900 turbo and the battery also went dead trying to start the car. after replacement the car starts and idles great but will not rev up. fuel pressue is good but the weird thing is that the tail lights do not work neither do the brake lights, the turn signals are constantly on but not flashing and the rear fog light indicator is on the dash. if i put remote 12v to the pump and pull the relay under the dash for the alarm system i believe) EVERYTHING works correctly but has a fault producing an engine light. Everything worked on the car before fuel pump replacement and dead battery. i also got the car to stay running with the key removed when i pressed the rear fog light button.
