yeah as soon as the car starts it goes straight to 3000rpm and cuts off and if i start it again it does the exact same thing.before it wouldnt get any power to the fuel pump but it turned out to be the computer which i changed with 1 out of a 95 lumina withj a 3.4 in it,now it gets power to the pump but wont stay running.it didnt have any codes but when i took it top the shop this week they said that the antitheft code was coming up in the computer and the car dosnt even have an alarm system.by BTW before i put the 95 computer in the car it would start and idle real ruff then when i tried to hit the gas it stalled,that when i put in a new fuel filter and pump.
