Hey James==The wires to the injector are one hot all of the time and one pulsates as the ecm grounds it as the engine is turned over. TAke a test light and hook one end to ground and probe both wires on the injectors. One wire should have 12 volts. If not, check all of the fuses. If no fuses blown check the wiring. If you do have 12 volts, put the light from 0ne injector wire to the other and have someone turn the engine over. the light should flash. If it doesn't, check the wiring to the ecm. Goodluck, Joe
This means the engine is running extremely rich. This can be causes by a leaking fuel pressure regulator or a stuck open injector.- TechJK ------------
There is a noid light that will check injector pulses from the distributor. It plugs into the injector plug. Most common failure for inop injector is in the distributor module. Also check fuel pressure to see if the fuel pump is operating correctly. It should come on for 2-3 seconds when ignition key is turned to run. Chevy guy denver
From your description I would guess that your car has a bad fuel pressure regulator. To check the fuel pressure regulator remove the vacuum connector from the throttle body. If gasoline comes out of a vacuum line the diaphragm has ruptured allowing excess gasoline to enter the intake through the vacuum line. If that is the case you will need to replace the fuel pressure regulator.
The traction control light will come on in an 02 Cavalier when the throttle postion sensor is going bad. It's not hard to change, a little hard to get to though. It is attached to the throttle body on the passenger side of the engine. It receives the throttle position from the butterfly inside the throttle body. When the trac off light comes on and you slow down you would feel like the car is trying to stall out on you a bit if it is the TPS. Not a hard repair but not an easy part to get to, new one costs about 20 bucks or so.
The cost isin't to great, but, the pain comes with the installation. Drilling the rivets,removing the window,removing the window regulator,then the window motor and then replacing it all back to where it was. Expect a few cuts and scrapes....
yes it comes stock
it is mounted to the fuel injector rail where the high pressure comes from fuel pump and pressure is at a set psi per engine there is also a vacuum hose that raises the fuel pressure about 8-10 psi when load is applied on motor to give a boost of power
No you need to change the regulator on your alternator or you alternator, which comes with a new regulator.
Throttle comes from the throttle wheel on the joystick else f3 f4. Banking by joystick
TRY REPLACING THE FULE FILTER.YOU ALSO COULD HAVE CLOGED FLUE INJECTORS TRY SOME INJECTOR CLEANER .OR YOUR LOCAL SHOP CAN HAVE THEM BLOWN CLEAN Check the wire that goes to the O2 sensor, it easily comes disconencted in the little plug that clips onto the radiator next to the PS pump. If the above answers don't work, try cleaning or replacing the idle regulator (it can get a lot of carbon buildup). It's on the throttle body where the air intake links up and just behind the throttle cable. Held on by two star bolts. -Jegoyet
Shorted voltage regulator,
