N0 p0wer to fuel pump - 2008 Buick Lucerne CXL

run the fault codes and look for a sensor that has activated the rpm limiter

fuel pump working?
injectors spray?
put some fuel 3 spoons in the air inlet and crank the engine
should start for couple of seconds the ignition is ok.
good luck

fuses first.

So do i by the sound of this question

Run a wire from the ground lead on the headlight socket to the battery negative post, and see if that works. If you got 12v to the light and it isn't working, it almost has to be the ground.

Give me some more information about this problem. May be i can help.

The problem is your Fuel Pressure Regulator. this is really common on newer cars to go out.here is the way you can check to see if that is the problem. Locat the fuel rail on the engine. find the little round valve looking thing on the fuel rail that looks like it has a vacume line hooked to it. This is the Fuel Pressure Regulator. All you have to check it is pull off the vacume line going to it and if there is any fuel that comes out of the top of the valve or out of the vacume line this is the problem. there should be no fuel comeing out of it or the vacume line. and this will not cause a check engine light to come on. The regulator could run from $50- 130 depending on. Hope this is the Answer you were looking for

Welcome to FixYa.com Look to where the drive belts are and you will see a cap black with power steering written on it, Regards, Lee

check your coil packs i have to replace them after about 30,000 miles. its most likley on the leading plug you would hardly notice a trailing plug not firing

The cheapest way to go is to change the fuel filters first and the air filter. Then I would change the crankshaft sensor.

You may have to bit the bullet , and have the fuel pump changed before the fuel injection pump. The fuel pump in the tank can be loosing pressure to the fuel injectoin pump.
I think the lesser cost is the fuel tank pump vs. the fuel injection pump.

The system runs of fuel and air. No spark like on a gas engine.

So the problem can only be lack of fuel or lack of air getting into the vehicle air induction. A restriction in fuel or air will make the engine run poorly.
