you can get wiring and parts diagrams from www.autozone.com and its free.just sighn up if you turn the key on but not start you can hear the pump slightly if you want to test the pump get 3/8 hose 2 feet put one end on the fuel pressure regulater its on the end of the fuel rail right side then the other side of the 3/8 hose put in a fuel can after this turn the key on but not start for a min.then check if there is fuel in the can if there is nothing in there fuel filter or fuel pump, if there is fuel in there then something with the inside distributor or spark . the 3/8 hose should be about 2-3.00$ can should be 1 gal. for 4-7.00$ this is better than over 100.00 for part the pump is in the tank so labor will be alot. hope this helps.
