P0321 Spark Reference Circuit. The spark reference signal is used by the PCM to improve ignition timing accuracy during crank and at engine speeds of up to 1,200 RPM. The spark reference circuit allows the use of ignition control mode below 400 RPM, eliminating the need to utilize module mode during start-up, and also allows the PCM to calculate true crankshaft position in 1/6 the time that use of the fuel control reference signal would permit. During normal operation, the PCM uses the spark reference signal to control ignition timing until the engine speed exceeds 1200 RPM, at which time the fuel control reference signal is used. There is no connection to the TCS.
If everything checks ok then the PCM is defective PCM.

SOURCE: replacing bad camshaft position sensor

  1. Disconnect battery ground cable.
  2. Remove water pump pulley attaching bolts, then the serpentine belt and water pump pulley.
  3. Disconnect sensor wiring connector and remove sensor retaining bolt.
  4. Twist and pull sensor to remove.
Reverse procedure to install and prior to installing new sensor, lubricate sensor O-ring.

It is located under the water pump. Make sure when you remove the sensor that you rotate the crank shaft and look in the hole to make sure the pick up magnet is still in there. Sometimes they come loose and cause a no start or long crank. You will need to have the code cleared still.

SOURCE: 2001 pontiac cowl pack not fireing.

Here is a diagram of the firing order for you 3800 engine. Cylinders 1 and 4 are misfiring because the operate under the same "Coil Pack" and the coil pack has unfortunately gone bad. O'Reilly sells them for between $30-50 depending on the amount of warranty coverage you want. To replace, simply unscrew the screws that hold the coil pack in place. WAIT before unplugging the plug wires. Place the old coil pack and new coil pack next to each other, unplug one plug wire, then plug it to that same port on the new coil pack. then do the same for the other plug wire. Then screw your new coil pack in place, and start you car. should run fine!

1999 Pontiac Bonneville-My fans don't work, lose coolant very fast not sure where it's going? Hasn't overheated, but I don't drive far. Planning to take 1500 mile trip at end of month?, no...


I assume it's the 3.8 V6? They are notorious for intake gasket problems. The fan problem could be a few things, fuse, relay, ECT (electronic coolant temp sensor), ECM, Do the fans come on when you run the A/C? Hope this gives you some ideas. Let me know a little more and I'll try to help. TJ

I have a 1998 pontiac bonneville 3800 v6 and all of sudden it wont start. i have had the battery,alternator and starter checked out fine. all power is working. lights, radio, power windows etc...what is...


This is most likely a break down in the security anti theft aspect of the vehicle. When the computer can't read the keys transponder or chip properly, it goes into anti theft mode and turns off the starter. Check out this link for info and answers. You can fix this yourself. http://vatspasslockpasskeysecurityhelp.yolasite.com/
