No spark, no power to fuel pump.

[sike]

I can't get my car to start. It cranks, but I have no spark and no fuel. I just tested the fuel pump and it works fine. Apparently it is not getting power. The motor is a 6 month old remanufactured jasper engine. I don't remeber if it came with new sensors or not, but I would imagine it did. I don't see the CAS or CPS going bad that quickly. ECU? I haven't had any check engine lights except when it stalls. I'm very puzzled here. If I don't figure it out by the end of the night I'm going to have it towed tommorow. I bought a new crank position sensor but the connector for it is 10 day special order. :-/. Any ideas? Diagnostic methods? I'm strugling to keep myself from blowing the car to peices, I haven't driven it in over a month! AHH. Any suggestions would be helpful. Thanks!

The first thing I usually do for diagnosing is check all the fuses and relays. If they are all good, start at the malfunctioning component with a voltmeter and work your way up the circuit towards power and ground sources. When you find the voltage to go from nothing to 5 or 12 or whatever it is supposed to have, you have found the problem.
