This is from hmaservice, it references a special service tool for removing the fuel pump. I'll see if I can find info on it.

Fuel pressure test parts wont remove the lock ring for the fuel pump module..

There is a service tool that engages the ears of the ring to release it..

When you get module out, install new module in it place,, and there is new tube that goes along with it,, seperate part..

Look at connector on old module, see if lug burnt up/overheated -- see pics

From my 2008 Sonata's manual:

"Running out of gasoline may cause the engine to misfire and result in damage to the catalytic converter."

Yet they still instruct:

"Start the engine and wait until fuel in fuel line is exhausted. After the engine stalls..."

I know, the argument will be that doing this once won't hurt anything. Uh-huh. I guess it's another case of "What you don't know won't hurt you".

Was there any code to indicate it was a pump failure? I am curious to learn how did you test it for the pump problem?

First hint of the module going away is long crank time or constant crank with no fire.. have assistant wiggle connector around or hold it to one side to make better pin connect, and it may fire up and run, then die as connector wiggled.

Pump itself not been failure item, it is the poor connection that deliver needed power to the pump... see the pics above of the darkened terminals and burnt plastic.

Is this a problem with the later NFs or just the earlier ones?
