No strange noise. Can you recommend a good but inexpensive diagnostic code reader for T5 2.3L manual transmission?

Its a new battery and I put full charge on it after installing the pump and before trying to start

Just don't understand why before installing new fuel pump the engine would run briefly with starting either and now with new pump and pressure at the fuel rail and using starting either the engine will not run?

New fuel pump and now have fuel pressure at the fuel rail. With the rear seats not reinstalled will this cause the engine not to run? Because it did with either before the new fuel pump. Thinking it might be some safety issue because rear seats are not connected.

How do you attach a photo of the relay box? Trying to find the fuel pump relay on 2002 V70 Station Wagon T5 M SR

Thanks but I don’t have that access on this 2002 v70 T9. Mine is under the hood on the drivers side. Will try to post picture.

What is the exact location of the fuel pump relay in the 2002 v70 manual transmission? Having issues with not getting fuel to the engine and not sure if the pump is working or clogged since the car has been sitting up for several years. Either will get it to fire up but will not keep running.
