I'm still chasing this "cranks but won't fire" problem on mine. I have changed the IM, the CPS, tested the harness between CPS and IM, all fuses, tested the ECM and Jet chip, new battery, coils are new MSD 6 months old, all new injectors, have key on power to the coils, IM, and computer. NO trouble codes. Had the plenum off a dozen times.. Checked for bent pins on the IM. really causing me some problems. Any OTHER ideas?
