secondary injectors are not opening
hey guys, my secondary injectors are not opening. i adjusted my tps so the car idles nice and smooth now, but when i am accelerating, i cant get above 4000 rpms unless i am real easy on the gas. if i hit the gas, my secondaries wont open and the car just bogs really bad and wont go above 4k rpms. i just took off my air pump (it wasnt hooked up cause i have no cat) do i need to block off anything after removing it? i didnt think that removing my air pump would have anything to do with it, but thats the only thing i've done since this problem popped up on me. could really use some help.

Worked fine until you removed the air pump??? So you disturbed something. Probably knocked off the vac line that goes to the boost/pressure sensor, maybe. That does not hold a lot of water if I think about it tooo long. TAke a look and see it that vac hose if off on one end or the other.
Yeah. On a turbo the whole upper has to come off. Probably not that if its a turbo. On a n/a, it coulda happen, not a turbo.

Secondary Injectors
Will the Secondary Injectors being mucked up cause the car not to crank? It turns over and acts like it wants to crank with the combustion poping... I know my left Secondary injector is leaking probably because of the O-rings but would this prevent the car from starting up?
A. I got gas in it...
B. Fuel Pump is new
C. Gas tank has been cleaned
D. Apex Seals seam to be fine one had carbon build up but the ATF treatment should have taken care of it..
So would it be the Secondary or Primarys to prevent from getting cranked?
I can spray Starter Fluid into the manifold and it starts for about 3 seconds and shuts of...
Anyone with any ideas? Much Thanks Appreciated...

ATPEAK23.....Secondarys don't come on line until approx 3500 or is it 3800 rpm? Most likely not them keeping a car from not starting.
TURBOIIFC........That remark I made was for JACOB... He said all was well until he took the airpump off, so I figured he knocked something askew. Could not have been the secondary injectors because they are buried and untouchable.
TURBOIIFC.....I do agree if the car boggs at 3800 that it has something to do with the secondary injectors not coming online. It can be as easy as the injector plugs falling off, bad spliced wires to the secondary injectors, someone putting the wrong impedence injectors in the secondaries, a lot of problems have been solved either with adding extra grounds to the existing ECU grounds or just repairing the bad grounds that already exist for the ECU. Theres a gang of grounds for the ECU under the intake manifold that have to be grounded. Theres the old standby of adding ground to the existing ground on the boost/pressure sensor. And when did the condition of bogging at 3500 happen? All of a sudden one day or after some maintainence had been done? To prove the injectors in the secondaries are good/bad, just swap them with the primaries. If bad, good luck starting the car again.

ATPEAKII ......jumper your fuel check connector and try starting the car. That would make your fuel pump run for sure. New fuel pump? Has the car run since you put it in?? What is the new pump? A WAlbro??? Anyway. only the primaries should be a pumpin fuel below 3500.

update, i blew the 15 amp fuse that sticks out a little bit frm the rest of the fuses in the main fuse box under the driver side dash. we replaced the fuse now secondaries are online and pumpin all the gas i can give em'. NOW. TurboIIFC... make sure you check that blue 15 amp fuse right in the middle of the fuse box, because i replaced mine and problem solved. thanks for the suggestions guys. oh, also... spray a little bit of carb cleaner on the secondaries' electric plugs... i did that and it got everything in there looking nice and clean. btw HAILERS... secondaries come online at 3800

scratch that fuse thing, that was only for the interior lights. it seems that i cleaned out the secondary injector electric plugs good enough with the carb cleaner to get them to work temporarily. i say temporarily because they went out on my way home so it looks like i'll have to take my top intake off to get to the fuel rail. one question, do i have to get a gasket when i put the top intake back on?

ATPEAK23. Ihad the same problem on my n/a 87. I found the door on the afm under the air cleaner was not opening. I removed it and cleaned it with some carb cleaner until the door opened smoothly. Now car runs fine
