My 1994. 98 olds will start and drive just fine but when I shut it off it won't restart I had the fuel pump changed but once it cools down it will start back up .please help me this is my main source.

SOURCE: PROBLEM STARTING CAR AFTER RUNNING IT ON SHORT TRIP

SO YOU SAY YOU DON'T HEAR THE FUEL PUMP WHEN IT IS HOT, I WOULD LIKE TO KNOW IF THERE IS SPARK WHEN IT WON'T START. BECAUSE IT MAY BE THE ECM UNDER THE COIL PACK SOMETIMES THEY ACT JUST LIKE AND OLD COIL THAT GETS WARM AND WON'T START WHEN IS GETS HOT. I WOULD MAKE SURE IT NOT GETTING SPARK BEFORE CHANGING THE ENGINE CONTROL MODULE BUT IT SURE SOUNDS LIKE THAT TO ME. I SURE HOPE THAT HELP YOU OUT AND IF IT DON'T LET ME KNOW HERE AND WE CAN DO SOMEMORE TROUBLE SHOOTING, OK THANKS BEAR001

SOURCE: New fuel pump.............

hi there i do believe you have a faulty or leaking injector because it should stay pressurized when you shut off the engine

Have you changed the crankshaft position sensor

Good Evening, you might want to check those injectors, I can not remember for certain but that setup was sequential and when one or two have a problem it would take out the rest. Ohm out the injectors and see what you have there.

I had the same problem, had the crank sensor replaced and problem went away.
