2008 DTS cranks but will not turn over

Is the fuel pump working? Normally they make a faint humming sound.

How would I test the sound? Just turn the key?

Turn the key on and listen at the tank, the pump might stop running if the fuel pressure builds up so a helper might make it easier. You can also check for fuel pressure at the fuel injection rails. There should be a small test port that is used to test fuel pressure.

cannot hear anything. it is brand new form an auto parts store. was there anything of a switch to turn on? we simply placed it into the tank.

If the fuel pump rely burned where I can see black on it and the block has burned on it, would I need to replace the fuse block even if other areas of the block are functioning? The fuel pump relay does not seem to be working the new pump I installed. The makes no sound that shows it is functioning.

My 2008 DTS done the same thing. I had to replace the black Fuse Block under the back seat. I first replaced the fuel pump relay switch & fuel fuse. There are 3 different fuse boxes on the 2008 DTS's.

where are the other two box because we have done all of the above

Maybe a new key fodder cause when the fodder isnt ableto read it doesn't allow the car to send message to engine to say on. Maybe something that simple. Has to be the original key... Caddies are very sentive can't just use a key with no chip ...

okay so I have a 2009 Cadillac DTS where is he third fuse box

Where is the third fuse block on my 2008 Cadillac DTS
