If you have the tools to check fuel pressure, this will be the best way to check for fuel pump operation.

You check for fuel pressure at a schrader valve on the fuel rail.

It could also be an goofy acting fuel presure regulator

My 1995 Volvo 850 will not start. I think it is the fuel pump. I tryed a procedure where I removed the fuel pump relay and jumpered the sockets for blades 85 and 15. there was no help in starting the car...

another way to test it
unplug any fuel line you can locate tell a friend to start key one turn only if the line squirts fuel then pump is working and it might need regulator
if not then pump is gone

SLK stalling problem

no if the fuel pump is failing it wont start. what about fuel filter ? what you can do is find a shop with a scope and they can check the fuel pump on it and look at the wave pattern and can tell you good or bad. but when it happens and you cant hear it it is time to check it properly before it leaves you stranded.

F150 fuel pump replacement

You could have rust in your gas tank, what will happen if that is the case is crank and run and when the rust gets stirred up it will clog your pump and filter. After a while it will kill your pump, and ruin your filter, and cause it not to crank at all. I would drain the tank and look at the fuel as it comes out if it has any red in it that is your problem. I had the same problem and that sounds just like my problem. I hope that helps you out.
