The secondarys wont open up. the move freely just rebuilt. do they open when sitting still or does the car have to be moving. Ive reved up to 6g nothing. electrical maybe?

its a 91 na the 5th 6th ports wont open

 

How do you know they dont open?

They are supposed to open around 3800 rpm...under load? Probably, I dont know. It seems logical.


Did you remove the air pump? If thats the case, theres your problem.

 

They only open under load.

This has been covered many times.

 

ill check thanks

ive heard peaple say they can see them open sitting still

 

they are wrong, unless you are flooring it in neutral.... but even then I doubt it.

 

like aaron said covered a zillion times and open only under load...driving

there is a test in the FSM and prob faq's etc or threads by other noobs

 

tried all that
no power to the switching selonid it flow fine in checks. Ive look all over for an hour nothing with my problem

 

Since it's an S5 I'd check the air pump while you're at it, pressure from that is whats us to actuate the 5th and 6th port.
Where in VA are you?

 

christiansburg. its sw va. The air pump work but im supecting juck in the line. presure low at selonid. I blow it at and check thats for the ideas

 

You can make the secondary injectors come online in your driveway. Do like the FSM suggests. Remove the vacuum hose from the boost/pressure sensor. Cap/plug the line.

NOW, each time you rev to approx 3800rpm, the secondary injectors WILL come online. Even in your driveway. You'll know they came online because the engine will sound *funny* as they come online. What'll happen is the duty cycle of the primarys will be cut in half as the secondarys come online. The airflow won't be ideal so the mixture will be a bit *off* as they come online resulting in the *funny* sound of the engine at approx 3800rpm.

 

Only on series four cars, not series five.

 

I think what he means instead of secondaries is his 5/6 ports...

 

There should be 12vdc on the black/white wire anytime the key is ON or better.

The other wire on the plug is controlled by the ECU and the ECU puts a ground on that wire to operater the solenoid. You might try putting a gnd on that wire when the engine is idling to see if the actuators work or NOT. As in leave the plug on the solenoid and backprobe a gnd to the wire that is NOT black/white.

 

is this thread about auxiliary ports or secondary injectors?

 

Your right. I just saw secondarys and...........assumed without reading the whole thing.

And it's not the switching solenoid, its called the 6PI solenoid and has a brown electrical connector on it. Only operates under load unless you jumper a gnd to the wire I mentioned in a post above. Then it should open and feed air to the aux ports actuators and they should operate.

 

Just put grease on the shafts, take for a spirited drive and see if the grease has wiped off.

 

I fixed it. They wernt opening. I had power to the switch and the switch tested fine. where it plug up there wasnt making a good conection. A little corrosion in side the plug. I stuck the test light in the back and it checked out fine so i ruled it out to early. Cut the wires and put to knew spade ends on and now its like i got a turbo. thanks for the help everyone.
