Question about 1987 Pontiac Grand Am

1 Answer

1987 Pontiac Grand AM power problem.

My car would not start so we took it down to a shop and they said the fuel pump and fuel injector are bad. Had them replaced. The car runs now but the problem is when you are driving down the street or hwy and you push the gas pedal down about half way the engine looses power. I have to gradually increase power. I also replaced the spark plugs and I am getting ready to replace the fuel pressure regulator. Is there anything else I need to look at? And which relay is for the fuel pump? So I can depressurize the fuel line.

    Thank you for trying.

    After replacing the regulator, I am still having the same problem.

    This car used to start-up and had no running problems until the fuel pump went out. The mechanic that fixed the car said that the fuel injector also was bad. Every thing was replaced and now the car starts up really ruff and has no power when trying to accelerate. A strong smell of gas is noticeable when the car is driven off. Can there be a possibility that the computer needs to be recalibrated?

It sounds like it is the pressure regulator..on the cover of the relays inside on the top there usually a diagram of which one it is.. if not i think its the one on far right just pull it out start car it will die out that will relieve the pressure ..

Engine won't start. It will run with staring fluid and then dies.

Check fuel delivery. Filter may be clogged or pump may be bad.

Car turns over but won't start fuel injector fuse and ignition fuses are good but no power is getting to them. also the stereo and wipers only work when ignition is on accessory. when its on r

Sounds like it could be a bad ignition switch-the electrical part, not the lock cylinder. When key is in the on position (run), those fuses should be powered. Are all the maxi-fuses good? They distribute power throughout the car's electrical circuits-like the fuse panel, for instance, so check the maxi-fuses. If good, probably the ignition switch is bad.

The fuel pump fuse keeps blowing in my 92 grand am

So it is the injector fuse, not the pump fuse? The injector circuit must have a short in it, or an injector may have a short and be bad. Have your injectors tested with a "resistance test"-they do not have to be removed for this.If injectors test out good, you need to inspect the injector harness for bad wiring. Maybe you missed some of the melted wires?

Car not starting, no fuel getting into engine

Start with checking your fuel pump and injector mini relay. Fuel pump relay is #18 and injectors is #48 and is located in the fuse box under the engine hood.
Also inspect your ECM fuse, the fuel pump get's it power from the ECM fuse and at wost. It's your fuel pump that has gone bad and that is located in the gas tank, but make sure your fuel filter is not to dirty causing fuel restriction and replacing that will address that issue.
Thank you for using fixya and keep us posted.

It is either out of gas,and the gauge is wrong,or the fuel pump has gone out,the sound does not always mean the pump is pumping,just that the motor made with the pump is running,pump still could be bad.

I just want an estimated time it takes to change a fuel pump in the 2002 pontiac grand am se? (it's in the tank and when I take it in the shop, I want an idea, so as not to get ripped off on the time it...

Any repair shop can look up the time in the labor manuels for you. If you have a couple days and enough tools do it your self. The main issue is how did you test for a bad pump and is that your problem??

I got a 1997 pontiac grand prix gtp coupe. the low coolant light constantly flashes. the coolant fluids are full. i just bought it and i am a little frustrated.

Sometimes the float in the low coolant sensor gets stuck.Find where the electrical connector is on the overflow tank and lightly tap on this area.This might dislodge it,if its stuck.Good Luck!!!
