Help with 94 Park AVE

[Demetrimosl]

My car started running rough all of a sudden sputtering stalling and cutting off after about 20 min,Now i can not get it to stay running for over 2 min, Why Does it Start up run and then sputter, stall, backfire from under the hood and shut down ? I changed the fuel filter and the pump and pressure seems to be ok -What next Thank U

Got spark and injector pulse when it stalls and won't start, basic checks to be done.

I,m not understanding what i need to do.

Check for spark at the plugs, see if you have fuel pressure, when it stalls.

You would have codes after all that missfire & stalling. We could continue to guess at a cause, however we need more information to really narrow it down. Maxwedge is asking if you have spark at the plugs when it stalls. You say you have a new fuel pump and pressure is ok, however how long does it hold pressure? How many miles on the car? Give us some feedback on the questions, so we can help you.
