I have a 98' Grand Am GT 3.1L V6 with 88k miles. As of this afternoon, the engine turns over but will not start. The engine is getting gas but no spark at any of the three coils. I don't think all three coils would go bad at the same time so I suspect the Ignition Control Module or a Camshaft Position Sensor may be bad.
Is there anyway I can test the ICM or CPS with a meter? (Called Autozone and they can't test it. The Chilton book has no information about testing the ICM or CPS, only details how to take out and replace).
The car had a full maintainence (new plugs, new wires, fluids changed, new filters all around) less than 1000 miles ago and was running great up until it wouldn't start this afternoon.

you might want to check the distributor cap, and the rotor inside it. that can be the cause of the problem, and it's an easy fix too. since it's getting gas, i don't think it has anything to do with then fuel pump, lines or filter. check the ecu to see if there's any code lights on it. sometimes ecu's don't set the check engine light off for certain codes. also, if the timing is off, the might not run either. anyways, hope this helps, and good luck!

If you just had a full tune up less than 1000 miles ago, bring it to the place that performed the tune up. It is possible they could have used incorrect spark plugs and wires.
But no, there is no way to use a meter to check your IPM or CPS. You can test individual sensors but it is a royal pain in the you know what. My guess is that you need a new coil pack for the three cylinders that are not firing or a crank sensor.

you need a schematic for your wiring. is there a fusible link in the system? the ignition module and cam or crank sensor are good ideas but if you have it scanned it should have a code set. I'm not sure about your model but some GM's you can jump the diagnostic connector and get the codes with the check engine light. check the advance auto or auto zone sites for instructions for that.

Could be many different things...... My guess world be the control module. Its under the coil pack......

Ingition control module sounds good.But it all starts with the ECM it sends power to the ignition module.Also check for blown fuses esp the ecm fuse.

CHECK ALL FUSES THEN HAVE IGNITION MODULE CHECKED AT LOCAL PARTS STORE ,ALSO CHECK CRANK SENSOR,CAM SENSOR,CAN BE COMPUTER
