Injector o-rings seal the injector into a port of the intake manifold. Each injector sits in it's own runner of the intake manifold and when they wear out from becoming brittle with age and heat fluctuations they will become brittle, crack and cause a vacuum leak. Air that isn't metered through the MAF just behind the air filter will enter the intake manifold at the injectors where there should be an air tight seal. It will cause a miss at varying engine loads and maybe turn on the check engine light if the amount of air entering the engine through the vacuum leak is higher than the programmed tolerances.
I've got an 01 cvpi...same thing happened to me when I didn't replace them when I changed intake manifolds.
you have bad orings, wrong size, orings or you broke the other injectors or the their orings
it is orings of a family's name
They keep your shafts from getting loose, especially metal ones.
I have the same problem, I check theinject spark and fuel on my 1997 GMC sonmoa And it still won't start check all the fuse's, then i check the timing chain and replace, Still no luck . I am hope someone will help us both.
No, vinegar is acidic and may melt your orings, and wont clean the gun very much. Use paper towels to wipe off dirt and use any air-tool lubricant on the orings and prevent rust. Water will ruin electronics and may cause rust on certain parts.
if the main spring gets stretched or damaged. It should not need to be replaced regularly like orings.
That depends on WHICH o rings you're referring to, and whether you just want a price for parts, or for parts and labor.
To replace fuel injectors you will nedd to unplug them individually and remove the fuel rail. the fuel rail is held down by 4 bolts- teo on each bank. you only have to remove the two bolts on the bank that you are replacing. if you are replacing injectors on cyl 1, 2 , 3 (back side) you will have to take the upper intake loose and move it for access. if you are replacing cyl 4, 5, 6 you can just take the bolts out of the fuel rail, pull it up, unplug injector and remove it. all that holds it in is orings on the top and bottom. just make sure you lube the orings on the new injectors and snap them in. this has been for the 12 valve. replaacing them on a 24 valve engine is about the same except the upper intake will have to come off for both banks
cause you have rubber orings that go on both ends of the injectors you probably need to replace them
Take the Cav to the dealership. Its worth the money to get them changed there. or you can jsut go to an auto parts store and buy them yourself. They roughly are $40-$50 per injector. If its a 2.2L you just unscrew the screws holding it down and remove the bar that holds them down. Then you can simply pull them out. Careful not to let it spray ya, cause there will be some fuel in there. You should also see 2 orings per injector. If you only see one, just stick the injector back in the hole, the other one should come out with it when you pull it out again. Hope this helps and it will save ya some $$$ To relieve the fuel pressure: remove the fuel pump relay and fuse (under the hood, left side of engine compartment), start the car and let it run until it dies, turn the engine over a couple of times to remove as much fuel from the lines and fuel rail as possible. This will reduce the amount of pressurized fuel and reduce the mess of removing the fuel pressure regulator and the injectors.
One of your o-rings is probably broken, or your valve is damaged. try taking it apart and replacing the orings.
Not aware that Hayward made motors. You need the pump seal, gaskets or orings and the tools to remove and reinstall the motor and the seal. The electrical connections and power need to be removed and or turned off at the circuit breaker.
