No spark and no fuel usually means the PCM is not getting an RPM
signal. This simply means that you can crank all you want and the
computer has no idea that you are cranking the vehicle trying to start
it. If it gets no RPM input VIA crank sensor or engine speed sensor as
it is called, the computer does not know what fuel injector to pulse at
what time and will not send a spark out put. it needs to see a signal
from the engine speed sensor. Check the crank sensor and its wiring,
and PCM pin where it receives the crank sensor signal because either
the signal is not being produced, or its not receiving it. As for
getting codes, your car is an OBD II vehicle. Get the battery charged
and run the car. Drive around for a bit. Shut off your car for a bit
then get back in and drive. Your check engine light will be back with
the codes. The first time you drive your car the computer will see the
fault and will set what is called a pending code. The pending code WILL however set a DTC (diagnostic trouble code) but WILL NOT turn on the check engine light. The second
time you drive your car if the computer sees the fault for a second
consecutive time, it will then set it as a current code and the light
will come on. These are called trips. The computer must see the fault
on two consecutive trips to turn on the light. Then three consecutive
trips without seeing the fault to turn off the light. The code will be
a history code but still accessable. The code will be completely erased
after 40 more trips without seeing the fault. If it sees the fault one
time, it starts all over until it gets to 40 consecutive times. I hope
this helps or at least gets you on the right track. I would also like to ask some questions, how long was the check engine light on for? Any driveability problems with the light on? When did the car just die? were you sitting at a traffic light, cruising down the road? any misfiring, rough idling, hesitation?
