Will not start at all

I changed oil and alternator was bad. Did that. Started up and pulled outside it shut off like it ran out of gas. Has spark, fuel pressure is great, injectors are pulsating. Have correct voltage. Compression is 180+ on all four cylinders. I swapped cam sensor with another tracker I drive everyday and it is new. I took valve cover off and all timing marks are spot on. I am missing something. Burned up a starter, so that is new now. Help! Could computer be bad? I am lost. Any help would be great. Lost my job and need the car. Thank you
