    Year/engine would help us give you more specific answers.

    Unless this is real old school (pre '88 or so), the way you test the fuel pump (and the rest of the fuel system) on a fuel injected vehicle (whether TBI or CSFI or other fuel injection system) is to put a fuel pressure gauge on it and see if the pump is generating sufficient pressure.

    Testing the distributor is usually about testing the consistency and quality of the spark. Does it fire consistently? Is the spark a nice blue color? If you pull the distributor off, are there any cracks or other indications that the spark is going elsewhere? Contacts corroded or worn?
