Hi I am new. I've tried about everything on mine and nothing changes. Runs really bad, fuel smell, no accelleration, idles rough, no power. No check engine light is on. I am at wits end on this one. Thanks for any ideas.

My car wouldn't start back up the other day, it tried to tun over but would not catch. I had AAA send a maintenance guy out, he tapped the fuel pump, car still wouldn't start. Once I got the car towed home, the tow guy had me start it & it worked but if I try to drive around the corner I have to constantly restart the car over & over. The fuel pump was just replaced & the previous owner states it also needs a new gas tank. What is the problem, I know its not the starter or alternator

Yes the check engine light is always on, haven't checked the fuel pressure yet. Previous owner states the fuel pump was just changed.

Since engine light is on than need to have the diagnostic code(s) that are stored. Most auto part stores will do this for free. It may help pinpoint the culprit of your issue. Post the code(s) you get here and I will follow up

1995 Pontiac Bonneville 3.8_mileage: 134,000. The fuel pump never turns off, from the time you start the engine you hear the buzz until you turn off the engine. The fuel pump was replaced prior to my buying this used car. Is the sensor that senses the fuel rail pressure part of the pump assembly in the tank or some where in line? I have looked at the fuel line under the hood and to the fuel rail and only see the injectors, no other in line sensors.

The fuel pump should be running all the time that the engine in your car is started and running. You should not be hearing a buzz from the fuel pump. You may have a faulty fuel pump or a partially plugged fuel filter. There is no fuel pressure sensor in the fuel line, the fuel pressure is controlled by a regulator.

The ecm probably has no power. Must diagnose the wiring, are you up to it? Or go to the dealer, or experienced tech! If you need the proceedures let me know I don't want to post em if you arent gonna do it!
