Greetings all. my wife purchased a 1991 saab cd turbo while i was deployed. when i got home i was told that it needed a new fuel pump in which i replaced. but here is the thing. i have power all the way to the pump but the pump will not turn on. what do i need to do?
If your getting power to the top of the pump at the harness and its not running, pull the pump back out and check the two power leads to the pump insert are connected. Jump power directly to the pump insert. If no go, looks like you got a defective pump. Justin Strictly Saab Melbourne, FL

LOOK UNDER CAR FUEL FILTER LOCATED FORWARD OF FUEL TANK. RELIEF FUEL PRESSURE BY DISCONNECTING THE ELECTRICAL CONNECTOR AT THE FUEL PUMP OR REMOVE FUSE.CRANK CAR UNTIL DIES FROM LACK OF FUEL. THEN REMOVE FUEL FILTER USE IN LINE WRENCH AND OPEN WRENCH.THIS KEEP YOU FROM DAMAGING FUEL LINES.WHEN INSTALLING FUEL FILTER THE ARROWS SHOULD BE POINTING IN DIRECTION OF FLOW.
OK, your turbo is bad now.
Sometimes bad things happen to cars. And the bad things show up one after another. I don't think that changing the fuel pump caused the turbo to go bad.
There should always be power at the injectors as long as the fuel pump is on. The fuel injection ECU provides a ground to the injectors to turn them on. You most likely have a bad fuel injection ECU. This is a very common failure on 88,89 and 90 SAABs.
