    When I was driving on the freeway the car turned off and wouldn’t turn on. Now the car just turning without starting. When got crank it the car starts to pop like if it’s about to turn on but doesn’t. I changed the fuel pump, fuel filter, crank and cam position sensor. Yes I did check all the fuses inside the of the car and the outside and even switched all of them around. I took the battery to auto zone and they told me it was a good battery with 100% charge. It’s full of gas too. I did the antitheft thing too by leaving the key turned for 10 minutes. It’s been a headache and a money pit, idk what the problem can be.

    Did the ECU throw any codes?

    Is your ignition coil crapped out?

    Have you verified spark and fuel pressure?

    Fwiw, popping through the intake could be from a timing issue. How many miles are on the motor?

    I was trying to check the fuel pressure but I guess s197 don’t have a valve to check it and I changed the sparks n the plug wires, the miles are around 110-120k

    I don't know if you ended up getting this one solved, but I had the same problem recently, cranked well and didn't start.
    Remove the intake hose and try cranking it and spraying brake clean or a starting fluid down the throttle body. If it starts running then its fuel related. Mine was yours might not.
    If it was and you tried the fuel pump and filter you must think it's fuel related. I had to put my spare on and damaged the control pack for the fuel pump in the spare tire well when I put the tire back in. I'd double check for voltage and ground coming and going to the fuel pump.
