Description: Question - Oldsmobile Achieva SL: 98 Oldsmobile Achieva with 3.1 V6. - CI. Find the answer to this and other Oldsmobile questions on JustAnswer.

98 Oldsmobile Achieva with 3.1 V6. Car was running and starting fine and than one cold day about -10 F it would not start. Turned over but did not fire. Checked fuel pump and was good, fuel pressure is 43 PSI. Then checked with an inline spark tester and no spark. Replaced all three coils and ICM with a good one from junk yard and started once and ran good but would not restart. Then I replaced the cranshaft posistion sensor behind engine with new one. Car started and ran good. Shut off and restarted and then would not restart.

Checked for ground at ICM and is good. Checked AC voltage from CPS and it was .6-.7 volts. Then I checked for voltage on pink and black wire coming into ICM and it is 12 volts. Tried starting engine and the voltage at ICM drops to 0. Is this a bad wire or ECM or PCM? I also checked and with key in on posistion there is 12 volts at ignition control fuse but when trying to start it drops to 0.

One other note is the pass lock system has been disabled on this car with a inline switch and a new ignition switch installed.
