1999 Honda Civic won't start! PLEASE HELP!

My wifes '99 Civic (EX, 220k, 1.6L) just died on her one day driving down the road. We have replaced the timing belt, fuel pump, main relay(was making clicking noise) but no progress. My brother-in-law is a mechanic and he drove it home a few times and it did it to him. His initial diagnosis was an electrical cluster because when it died he played with some wires and then it started. But when it did it to him 4 more times, he said it was a different wire every time. I thought that it might be an electrical problem but then I sprayed starting fluid into the throttle body and it started. Then I poured gas directly into the throttle body and it actuall ran until the gas was gone. I talked to Honda and they are lost. They had me check to fuel filter to make sure that fuel was passing through, and it was. Any ideas? Please help! We paid it off a year ago, and then this happened. It hasn't run for more than a day in a year. Thank you very much! :Mrgreen:
