1989 caprice was running greatafter replacing the battery.. One month later the cars starts up then dies afer gas petal not being hell down.

SOURCE: 96 pontiac sunfire bogs down and dies when I apply the gas.

as far as the bogging and dieing,it sounds like the tps.a simple trottle body service would fix that.for your new problem you need to some test before pointing to a salution.start the car and cover your tail pipe.as pressure builds it push you hand off.a clogged cat will put to much back pressure on the engine.i would un plug the mass air flow sensor and try running the car.this will turn on the check engine light.check your air filtter and plugs.also check your wires.a nother test is a coil strees test.(you have to go to a shop for this)if the car runs ok with no load but spitts and sputters in drive you may have a openning coil.checking with a meter only works if it does not run.last but not least while you at the shop,have them check your timing.a faulty cam sencer will bog the car down with bad timing advancement but not throw a code.
hope this helps,remember to keep it simple,expensive elec. parts are not always the problem

Thi is a fuel pump issue.

Testimonial: "it was what i thought but im thinking it could just be the filter needs changed"

SOURCE: Car will start but will not stay running-not getting gas?

have fuel injection system cleaned

Testimonial: "Thank you for the quick reply. This was one of my first thoughts along with possibility of a blocked fuel filter, fuel pump, or plugs/coil connectors."
