Thread: 2005 grand prix wont start

My grand prix ran fine the other day i went to start it this morning and all it does is crank im not getting any spark or fuel to the motor i checked all the fuses in both fuse boxes and they were fine there is also no trouble codes anybody have any ideas on what to check next?

i hooked up a timing light to a plug wire and a pressure gage to the fuel rail

Could be your ICM

Check your BCM. I've seen were a body control module fail and totally disabled the car.

A buddy of mine got bumped in the rear at a parking lot (he did not know it til he got out and inspected his car) But it would not start.

So he took his battery cables off his battery and connected the + cable to the - cable and grounded out the entire system for 15 min. It cleared his computer & drained all caps in the cluster.

Then reconnected the cables back to the battery and it started right up.

Worth a try if you have no other things to try.

I had the local auto parts store check the ICM and its ok.I also hooked the battery cables together and still wont start.If anybody has any other ideas please let me know

This is from my Alldata account on my'01 GT

"When the ignition switch is placed in the Start position 12 volts is supplied through the Park/Neutral Position Switch to the S terminal of the Starter Solenoid. Ground is found through the engine block."


Then check Theft deterrent control module


Hope this helps.

Did you check out your cam shaft position sensor?
