I'm a little late to the party...but there'* a few things I'd like to mention so others don't find this thread and have issues.

First thing to do is verify if there is spark or not. OP still hasn't done that. Sorry OP.. you should go do that right now. Then we know if that'* the issue. I'm not sure if you have an NA or SC motor and would like to know that as well. There is no magnet on the cam sensor, the cam sensor, senses the magnet in the timing gear. Which on an S2 motor, never seems to come apart like the common issue on the S1'*. VATs does not exist on the 2000 model year cars...not sure why you say that because he says the car is a 1996.

Hope this helps!
All I can see banging on a gas tank helping out is breaking the baffles in the tank and causing a person to need a new one because when they are low on fuel...it'll slosh and the car will stall. A pump can be tested at the schrader valve on the fuel rail, listening for it running etc. Lot'* of easier and less destructive tests can be performanced with less work.


Now then OP... you have a drag car, surely you have a plug wrench handy. Please pull a plug. Any issues or wetness? You say that you smell fuel. that means there is way too much. It'* possible the plugs are wet and won't fire. Priming the system a ton of times trying to start the motor before you changed the starter, could do this. Each time you turn the key..the fuel injectors pump fuel into the cylinders.

We should never assume you have no spark. You should check and be positive. If we think about how the various systems operate, where wiring is located etc, no spark should not have happened from a starter replacement. We should also never assume fuel at the rail, mean that we have fuel getting into the engine. A fuel injector fuse will keep the injectors from firing.

I've broken many things to learn what I currently know.

Ok
1st if you read the beginning post i did check for spark and there is none.
2nd it was mentioned about a 2000 because i changed the motor, the body is a 1996 but the motor is out of a 2000 grand prix.
3rd all fuses are good so its not the injector fuse
4th yes i can smell fuel but thats from trying to start it a bunch of times checking various items. After letting it sit for a day or two the plugs do dry enough to try starting it again.

I agree that changing the starter and alt. Should not have affected this car but it did... All fuses are good all wire and connections are good the bottom line is there is no spark now..... I have a 9. Sec mustang i built from the ground up and have never seen anything like this. I am posting to get other options to try figuring it out without spending a ton of money at a shop for something stupid....

Must have missed the no spark being confirmed. How did you check and determine there is no spark? Reason I said what I did about the 2000 is the motors are identical... the issue you are having would be related to the car being a 96 or the motor which would not bring the 2000 year security system into the mix.

Your year has only the one battery cable going to the starter and one soleniod wire, so that rules out missing a wire when doing the alt.

Thinking of where you were doing the starter etc.. there is nothing in that area. Check your connections and look over the wiring harness from the FPR area where it connects to the ICM, crank sensor and cam sensor.

Did you happen to rotate the motor by hand for any reason? This shouldn't cause a problem...but there'* a small chance the pcm isn't sure where crank and cam sensing should be if it was moved. Very slim chance.

I talked to my mech and he is going to test the systems monday with his testers. I have checked every wire and connection under the hood for anything bad but all looks good.... I called a friend and he said it sounds to him like the crank sensor went bad... I guess maybe it might of just been bad timing with the install of the new parts ???????????
