Thanks again.

Terry,
Both the FP and ignition sparks are easy to test and verify. Some people like to suggest pulling the AFS (air flow sensor) plug but with the engine installed getting the clip off is quite tedious or difficult. I work with the engine on my test stand and I know I can not remove the clip conveniently with my eyes closed so I never recommend this method.
Inside the trunk luggage is the front fuse panel. The FP relay is usually RED in color and sometimes people use the regular black round relay. Do you have a wiring diagram you could use for reference? This topic has been widely discussed so you would not have problem searching for additional info. The FPR (fuel pump relay) has 5 terminals namely:
87a
87
86
85
30
With the ignition switch @ON position, power is supplied to 87a & 86 at the socket side. Connecting terminals 87a and 30 will make the FP run. Using a wire jumper with fuse is highly recommended. Or an insulated wire would work too.
Now for the ignition spark test, use an inductive timing light. It is easy and simple. Or use the spark plug grounded to the engine for the test. This is a common test used by many.
Take a picture of the fuse panel and post it. People would be giving you good advises and directions to accomplish these tasks. If you are not sure or have any question about this topic, don't hesitate to ask.
