1994 grand am starting problems

[94 grand am]

i have a 1994 grand am 3.1 v6 automatic with 86 thousand miles recently had problems were car wouldn't run right, sputtering,chugging really bad when in gear usually just dies. hard to start if it does start. since then i have changed the fuel pump and filter full tune up intake gaskets and new injectors crank sensor and checked all fuses any advise would be greatly appreciated also installed new battery has 56 pounds of fuel pressure.

do you have a check engine light on? Since you covered most of the fuel system a guess would be ignition related, bad coils, bad coil ground, plug wires. All of these can be tested.

new ignition module and injectors all new wires and plugs coils were tested and are good car will start but at full throttle it acts like idle if i let go of peddle it dies also changed converter today still no change

Could be a bad coolant temp sensor.
