I couldn't even wager to guess what it might be then. Sometimes if the fuel system is still under pressure, the pump won't cycle on when you turn the ignition on. Let it sit for about 5-10 minutes and try it. You may have to check fuel pressure to rule that out if that's what you think it might be. Check the basic things first(cap, rotor, plug wires, fuel filter.) Those are often the most overlooked things and they can cause big problems. A buddy of mine has an Eclipse GS-T and got no power out of it. He was ready to tear down his engine, but it turned out one of his plug wires had a pin hole in it and was leaking spark. Damn, he still owes me a steak dinner.
Good luck.
