2002 buick century no injector pulse

No injector pulse. The shop can make it pulse with the scanner. But car will not do it on it's own.. Replaced several senors and ecm. It does not throw any codes with the upgraded GM code reader.

SOURCE: key will not start my 95 buick park avenue

does your key have a chip on it ? if it does , the problem is going to be that ,key chip only works with the original computer , until you have it reprogrammed by the dealer . this is an anti theft function to keep someone from stealing your car . there fore your car will not start until the chip matches the ecm.

SOURCE: need unlock code for 2003 buick century car radio

You will need to take the car to a dealership to have the service department unlock the radio for you. They have a special code to unlock the radio and then you are required to change the code to one that you will remember. An appointment should not be needed because this takes about 5 minutes. I do not remember the code, sorry.

SOURCE: 2002 Buick Century, when the tank is 1/4 full,

P0446 Evaporative Emission Control System Vent Control Circuit Malfunction

The evaporative emission control system checks to make sure there are no leaks in the lines that run from the gas tank to the charcoal canister and up to the engine. It also checks to make sure the gas cap is sealing correctly.
It may just be that the cap was not on tight and the code was tripped.

A dusty environment can also clog the vent line and cause this code.
Have the code cleared and see if it comes back. Some auto parts stores like Auto Zone can read and clear the codes for you.
Hope this helps.

SOURCE: how long does it take check engine light to go off

you can take of the ground of the battery of the car for 30 minutes and the computer will reset. if you drive around without reseting the computer might figure it out after 30 miles.

SOURCE: I have a 2002 Buick Rendezvous CX with a locked radio.

what you need to do is pull the radio out and write down the serial number then call the dealer for the code. they may charge you 15-25 bucks but that will save you some money

I'm not sure of engine Size? Did you check the crank sensor? Any applicable trouble codes? Do you have a fuel injector pulse, engine cranking?

My 2003 Buick century got hot and quit working now it only turns over and won't start


Can you check cylinder compression? Hope you didn't get it too hot?

Have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, check fuel pressure and injector pulse. Can you check applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader.

1991 Buick Century Limited 3.3L, 94,300 miles; stalls under load.


There should be a purple wire with white tracer from ignition module to computer. That wire carries rpm signal to computer, w/o that signal, the computer won't ground the fuel injectors. With the engine cranking, you look for a dc pulse on that wire. If you have a digital multimeter that has a tach--duty cycle or dwell setting, it should react to a dc pulse.
My info on your model year, isn't that great.

86 buick century 2.5l. car sat about 6 months, no start, but when fuel is added to throttle body fires up. when i pulled the fuel line from TBI it sprayed across engine compartment. but when connected...


pressure underhood is good. i'd check the plug conection at the throttle body(injector).see that the injector trigger wires haven't been cut or crimped around the air filter.the injector can be removed from the body for cleaning,but you may want a shop to do that with an ultrasonic cleaner.does it spray at all when cranked?check all sensor connections too.

Service engine soon light comes on my 2002 Buick Century that only has 54000 miles. What could this mean? Nothing seems wrong with the car. It is oiled regularly.


the service engine light means that the computer has detected that there is something wrong. it doesn't mean that it is anything serious. it could be something very simple. if you want to find out what it is exactly and avoid repair shop costs, take it to auto zone or another parts store. most of them have scanners that they will hook up and tell you why the light is on without charge.
