if you have spark; that means that opti high/low res pulses are getting to the ECM, and something else is likely going on.
do you have +12v to the pink wire at each injector when the ignition is on (car not cranking)?
if you're having a vats/security issue, it may still crank if the previous owner has bypassed the anti-theft relay thingie, but the VATS signal to the ecm that enables injector pulses may not happen. is your security light on?
