Warning: During the following checks there is a chance that the vehicle could lunge forward causing damage or injuries. Allow plenty of room around the vehicle, apply the parking brake firmly and hold down the regular brake pedal during the checks.
1. Automatic transmission equipped models have a neutral start switch which prevents the engine from starting unless the shift lever is in neutral or park.
2. Try to start the vehicle in each gear. The engine should crank only in park or neutral.
3. Make sure the steering column lock allows the key to go into the lock position only when the shift lever is in park.
4. The ignition key should come out only in the lock position.

If you have a standard transmission just let me know and I will tell you what you must do. Your welcome

Everything was running well with the new battery an alternator. It took alittle while to turn over sometimes so I thought a new starter was in the works in the near future, today it stopped turning over. Not dead, just not turning over. I got it towed home and took out and replaced starter. It started right up like 5 times. Then boom. Its not turning over, again. Just keeps cranking. How can this happen with a new starter? I'm really confused. It's stuck at a friends house kinda far away and I just wanna get it home. HELLLLP!!!

Definatly sounds like the CPS, to check to see if it is the CPS you try a few things.
TO CHECK CPS:
1. Disconnect the CPS electrical connector from the main wiring harness from the rear of the intake manifold.
2. If your working on a 91 or earlier model, connect an ohmmeter across terminals a and b (marked on the connector). The meter should read 200+- 75 ohms on a hot engine.
3. If your working on a 1992 or later model, Check the resistance between the B and C terminals (marked on the connector). The meter should indicate no continuity (open).
4. If the readings are not to specification, replace the CPS.
TO REPLACE CPS:
1.Disconnect the electrical connector from the CPS.
2. Detatch the CPS by removing the two bolts on the transmission bell housing on the drivers side, which are facing the firewall. Trace the electrical connector to the sensor.
3. Installation is reverse operation.
