Question about Chevrolet Corsica

1 Answer

The engine will stall after running for approx. 5 mins. I have replaced the fuel pump & screen,also the O2 sensor on the exhaust manifold. I was told that it could be an 1 or more injectors bleeding pressure off and causing the other injectors not to open, ultimately starving the engine of the required fuel to keep running

1st i need to know what the year of the car is, and what engine you have, also the very 1st thing u do with a problem like this is do a fault code test of the computer control unit, and as far as the part about the fuel injectors that is just plain rubbish.

    My apologies on yr. and engine 1990 Chevy corsica 3.1 multi port fuel injection. I have already done a code check and all it came back with was the O2 sensor. The following is more detaled info on my symtems.After sitting for a while the car will start and run briefly,after only a few minites i will begin to cut out just as though there was are in the fuel line. then it will stall, atempts to start immediately after stalling and it will only crank over, but not fire at all. I ahve traced the fuel delivery and I am getting fuel up tho the fuel rail. I do not have the pressure tester to run a pressure test at the schrader valve. I Also leading up to tis problem while the car was sill running, I was getting a strong smell of unburned fuel in the car. After describing all of this to my mechanic friend that was when he told me that it was possibly oane of the injectors or the pressure regulator located at the fuel rail

    U haven't done the most basic testing when it won't start, one, does it have spark? use a screwdriver with a good plastic handle and pull a plug wire off, then put the screw driver in the spark plug boot and hold the blade about 1/2 inch from any engine metal surface, have someone crank the engine, if it have spark u will see and hear the spark jump to the engine, it will be a loud snapping noise and a bluish/yellow spark, if u do have spark you need to see if fuel is being injected into the engine, to see if the injectors are "firing" go to a auto parts store like Napa or Carquest, buy a injector tester called a "NOID" they are about $5, this tiny little tool plugs into the injector harness at any of the 6 fuel injectors, when u crank the engine if the injector is getting a signal to deliver fuel the little clear NOID tool will flash rapidly, best if this is done in dim light like in the evening or in the garage. Below is a picture of a fuel injector from this engine.

    Guess I forgot to mention that I had already checked for fire. Did'nt do the the screwdriver in the plug wire thing,rather I bypassed the injectors and poured fuel a little directly into the manifold,and it started right up, but only for a few seconds which told me I was getting fire and air but no fuel. I'll pick up a noid tomorrow.and check the injectors. Back to my original post, that one or more injectors was bleeding off fuel into the cylinder and interfering with the total fuel pressure within the rails and affecting how the others worked. You were quick to say it was rubbish,but offered no explaination. My understanding of the injectors was that they worked not only by being electronically fired but also relying on a cerain amount of fuel pressure @ ea. injector. Do they only rely on the electronic signal from the control module? Any added info you might have would be greatly appreciated. Thanx, Woody

96 olds lss had fuel pump replaced wont stay started long sputter spits ect.


You better find a different mechanic . Before calling a bad fuel pump ,did he do fuel pressure test ? Did he test the electrical circuit ? Did he check mass air flow sensor ,injectors , fuel regulator , engine senors ? How many miles on the vehicle , is the engine in good shape ? Timing chain ?

Where are bank 1 and bank 2 o2 sensors on 2001 Chevy 1500?


The 02 Sensors are located in the exhaust pipe passenger side behind the catalytic converter. you'll see the wires on each one, you may have as many as four base on your engine size.

Code p1131 on 97 f150 4.6 on bank 1 what does it mean?


P1131--Lack of HO2S-11 Switch,Sensor Indicates Lean

Front O2 Sensor -- at converter inlet,pass side (Bank #1)

Could be ten things

Check that you have no vacuum leaks anywhere,including
the exhaust manifold & system

Check air filter cover & ducting for leaks

I doubt you have experience or test equip to test
the O2 Sensors, so replace both front ones, if you
have dual exhaust

1996 grand cherokee starts fine and runs great the first 5 minutes. Then it runs like ****..doesn't completely stall but runs really rough. Like it wants to stall but doesn't. Replaced the fuel pump and...


First thing is; When you changed the fuel pump, did you compare the 2 to see if they were identicle?, because it's possible that you could have the wrong fuel pump.. Second; you should have changed the fuel filter when you changed the pump, if not? you need to put a new fuel filter on... Third... It is possible for the upper o2 sensor, because on your Jeep, you have an OBD II system, which is, ( On Board Diagnostics II) and that system uses two "o2" sensors; One before the catalytic converter and one after the converter. The Primary o2 sensor is the one before the converter; The secondary o2 sensor, or catalyst monitor, is located after the catalytic converter.
The two o2 sensors work on an "open loop and closed loop". When the motor is cold, the o2 sensors are in open loop, which means they are not being used to monitor the exhaust gas, and when the motor warms up- after 5 minutes or so, then the computer switches to "Closed loop" and the o2 sensors are then used to monitor the exhaust gasses, so it is possible that your primary o2 sensor, or the one before the catalytic converter is bad.... But! It's very rare for both o2 sensors to go out at the same time.... I hope that answers your question & gives you an idea of how the o2 sensors work in conjunction with the fuel injection system.

1996 Neon is blowing black smoke from the exhaust.


If good, clean fuel, good spark etc. 171 is lean mixture according to my sources.. Thus I'd say if engine is being told from O2 sensor that mixture is lean, that would explain all the extra fuel getting ( dumped ) fed to engine. I guess i"d start by changing O2 sensor. (Oxygen sensor.) If it has 2, do the one upstream, closest to engine on exhaust manifold or pipe.
