Fuel ? problems '93 olds cutlass ciera

I have a '93 olds cutlass ciera 3300 v6. a month ago while driving on the highway it started backfiring real bad bucking and when i would push the gas it wouldn't go at all. then it would shut off i could start it back but when i put it in drive it did the same thing. a mechanic i asked told me it could be the fuel pump but somone else looked at it and unplugged this black box looks like some electronic thing and it is right beside the air filter on the left of it. it has AFH5OM-02E on it and right underneath it has numbers 3125. so my question is what is that, what does it do, what do you think the problem is by my description, and what would happen if i keep driving with it unplugged. i just started driving it again today after a month off the road. and i can't reach the person who told me about it. i think he said it may be some air fuel sensor or something with the air fuel mix. ive looked online and cant find the same part anywhere im not sure im hoping you can help me. thanks

    I've had this very same problem with mine. I went to 3 different mechanics and couldn't get any answers. I had changed the fuel pump, fuel filter, coil packs, spark plugs and wires. Then a friend told me that he had asked a good mechanic and had described my problem to him and this mechanic said that these cars are notorious for having an ignition control module foul out. It's the thin plate that the coil packs plug into. This solved all my problems. Hope it helps.

Is it possibly your TTC solenoid?We had the same problem with our car where it would stall out after being driven for awhile and brought to a stoplight,but would restart without a problem.I unplugged the ttc thing and plugged the hole and it hasn`t given us anymore grief at all.Nothing will happen to your engine from having it unplugged but I would advise covering the end of the plug with something as well as the female part it plugs into,just to keep road grime,etc out of it.Hope this helps!,...Ron

What makes the fuel pump not kick on on a 92 Oldsmobile Cutlass

There is a red wire close to the battery in the front. It's not connected to anything. Apply positive voltage and that will run your pump for testing purposes.

the most common problem next is the crank sensor. use a heat light to warm up the sensor to see if it is that. by using a heat light you can narrow down what part has the temperature glitch. Don't forget to try the engine computer.

Sounds like a plugged fuel filter. You might have dislogged some "crud" when removing the lines, etc... Can't be 100% sure without doing a test on the fuel system.
Good Luck.

1990 cutlass ciera w/3300 v6, won't start, fuel presure is 45psi, has good spark, has new crank sensor. still won't start, what next.

If it has spark, the crank sensor is working. If the fuel pressure is 45psi, that's good.

Are the injectors pulsing controlled by the computer?

When was the last time the fuel filter was chg.? If you can't remember or thats not an issue, than its time to do a fuel pressure test to determine if pump is weak, or on its way out.
