Will not start but turns over.

Start with your crank sensor. The possibilities can be a lot of things like your ECM, security system, wiring, etc.

I agree with brotherben. I looked at info for v6, showed two crank sensors, the one that is direct input to ignition module, is the one I'd look at. Did you check voltage and ground at ignition module? Pink wire is voltage, goes hot with key on and is fuse protected. The black wire is ground, check them both.

I just had this problem, the water pump was leaking and caused a short in something below it and 10 amp Fuse #37 was blowing and causing the problem even though it is not labelled as having anything to do with starting

I have a 2001 pontiac grand am GT and the fuel pump is working checked the fuel valve and has fuel going to it and checked fuse to ac and all fuse to fuel i have check security and did the turn to on and let set 10 mins also discounted the battery still cant get to start without starter fluid even when i use the starter fluid it still don't stay started just comes on for a min then shuts off please any ideas what it can be

Also has spark to it

My 2003 grand am had this same problem for months as for needing starting fluid to start. Under the hood there's a fuse box and my wife's car had an a/c fuse ( #37 on the box) that fixed the problem. Changes the 10 amp mini fuse and it fixed the problem. Hope this helps someone.

Hey guys I have a 99 grand am, just was having the same issue. My car would turn over, but wouldn't crank. After replacing several parts that I didn't have to, ends up being a bad mass air flow censer. Replaced it now irs running fine.

I have 2001 one Pontiac grand am GT and I did the ten min thing but the scarcity light want go off. An the car want stay cranked
