Well the pump w/o fuse is new - someone has likely rewired your fuel pump. Check the voltage at the pump to verify at least 12V.
Regarding your problem, it sounds like it may be either dirty filters/screens in the fuel system or tired pump.
I would start with screens/filters. First replace the filter in the engine compartment (use a filter that can handle the high FI pressures - no glass here); second, undo the banjo bolt at the kugelfischer - there is a screen inside which you can clean; and third, remove the fuel sender pickup from the gas tank in the rear - there is a plastic screen thing here which can become clogged with the junk floating around in your gas tank. I believe that servicing these filters should solve your problem.
If it doesn't solve your problem, you should test the function of your fuel pump. To do this you will need a fuel pressure guage (you want approximately 28psi continuously). You also want to test the flow volume - to do this, you will just pull a fuel line and divert it into a measured container to see how long it takes to fill the container (unfortunately, I forget the flow rate specs).
bastardized '74tii with most of this stuff still in place
: I pulled into work today and while i was idling waiting to get into a spot, the car slowly choked and quit. It would crank but not start. My mechanic was checking the fuse to the fuel pump and pulled it but the pump kept working--though not the tach & fuel gauge--both are on same fuse...??? He got it to start again but the same thing happened--slow fade and stop...Sound familiar to anyone?
