Need some help please Hey guys I'm hoping someone can help. I have a 97 Trans Am with only 60,000kms on it.
Wen I was driving home Friday afternoon after an hour drive it seemed to shift kind of weird between 1st and 2nd. I got home check the fluid and all was good. This was around 6 when I got home.
I tried to start it to go out later around midnight and all it does is crank over won't start.
I went to start the car the next afternoon and it started.
It didn't start right away the engine turns over a bit i much before it starts. I notice this in the past week almost like a carburetor car would. I thought this to be out of the Norm.
I put a clear spark plug tester on it and I have spark. After about 3-4 starts it won't start again.
Later my buddy came over and we heard the fuel pump kick on the car started and ran nice. Great spark from the spark plug tester.
Shut it off and started it again no problem.
The fourth time wouldn't start again and the light in the spark plug tester wasn't very strong.
I was guessing the ignition control module. But I went to AutoZone and they tested it (5 times) and said it was good..
So far I believe it's getting gas and enough the battery is good and the ICM tested good.
Any thoughts?

I forgot to add this
I took the ICM to get tested. Now that I've put that back in and together it just turns over and won't start at all. It still turns over took the ICM to get tested. Now that I've put that back in and together it just turns over and won't start at all. It still turns over like it wants to start the first time then nothing.

I would go buy a new Crank Shaft Position sensor......drop the starter and there it is. Swap it out. Put the starter back.
If it doesn't work....clean it off and get a full refund. Just tell them it wouldn't fit because someone modified your sensor port. They have no clue......
That sensor could just be totally failed now.

Well I changed the crank sensor. Which is in the front of the motor not under the starter.
Changed the fuel filter fuel comes out nice.
Still turns over won't fire.
I had it running for a bit. Shut it off and wouldn't start again just turning over.

Fuel pump on the way out or opti dying. Both can cause the same symptoms. Both suck to fix. You have to measure fuel pressure at the rail at a time when the car won't start to see if the pump is weak during a no start condition.
That code is Crank Shaft Position sensor......they are the same in what they do for both the LT1 and LS1......
You could have bad (NEW) sensor....its happen ed dozens of times. But you'll need to check the rest of those items associated with the CSP sensor code.
As far as Opti-Spark.....I have no experience with that.
