so i DO have an early 87 turbo 2 and i had purple secondaries that worked good but i thought that they were red till i pulled them out(i thought they were na inj.) well i bought a set of secondaires from a guy that were rebuilt and all the good stuff they look great but i put them in last night to find out they dont work but i also replaced the pigtails to. but my question is since im supposed to have tan inj. why would the purple ones work and could my inj. resistor box be bad? but then i thought well if that is bad then my primaries wouldnt work. im highly confused to why high impedance inj. would work in my car and its not a 87.5
???????

thx for any help in advance

About colors..............aftermarket vendors do not arrange the color to match the original injectors. Going by color sucks UNLESS it's a Denso and the part number is embossed on the side of the injector. Just my thoughts on COLORS to ID a fuel injector.

 

these are all factory rx7 injs.

 

you shouldn't have been able to plug in high impedance injectors into a low impedance harness because the connectors are slightly different due to a notch in them.

your car may have been hacked by someone who didn't know what they were doing.

good info:

That could explain it.

 

Definitely could.

I'm honestly surprised that you were able to pick that out from that thing he's trying to pass off as a "paragraph".

 

Yeah, you get used to people typing crappy. I used to do it (not that bad...) and then I realized people take you more seriously and you get better feedback if you just type legibly.

 

for starters this is the freaking internet not an exam paper and this car has never been touched by anyone. I bought it off of a older couple that let it sit for 6 years. so im guessing that my car is a frankenstein due to it being a early 87 but its actually a 87.5. its got to be other wise like the one guy said earlier about the injector wouldnt plug into the low impedance inj. plug. but call me stupid but this is how it really is and i mean it when i say that no one has touched this car.

 

what color were your primarys? purple ( stock denso) injectors tell me you have a 87.5 high impedence set up but they could possibly be aftermarket ones ( you really cant be sure ) esp if they dont match your tan primarys.

 

well i found my factory secondaries and they are tan 195500-1370 and thats the same injector thats i just put in last night but they dont work. the purple ones did work just fine so........ now what

 

Re: Not an exam paper - Yes, but like My5A said, you're more likely to be taken seriously if you type well.

As for the car, just because an older couple owned it doesn't mean that no one worked on it or did some hack job to fix it when something went wrong.

 

********* inj. resistor box be bad? but then i thought ********88

High inpedence injectors will work even if the resistor package is still in the car. And you'll Probably never even notice it.

High impedence injectors will work in your car but you Should take the effort to cut the solenoid resistor package's harness in two. Then put the resistor package on a shelf in the garage. Take the five wires on the cut harness and splice them all together and connect its plug back into the EM harness.

On the side of the factory injectors is a number. It will end in -1350 for n/a or -1370 for turbo.

 

so what your saying is you took the working factory injectors out? replaced them with the purple ones, which worked, then replaced them with some other new ones that dont??

or

the purple ones that worked were in there from when you got it ,and you decided to replace them, and the new ones, including clips, dont work? ( your orginal ones just came with the car as a spare or something???

 

why did you take them out anyway?

 

ok first when i got the car it wouldnt boost , and as time went by i swapped out misc. parts

to see whats wrong. i bought this set of secondaries from a guy on this forum and i got

them they were purple... me being in a hurry i didnt even look to compare them and put

them in and still no boost. meanwhile the problem persisted and kept getting worse and

worse like cutting out under light load. so i checked the fuel (walboro 255) thats is new

from the day i bought the car, the filter on the fuel pump was covered and caked with bad

gas corrosion and chunks of it, so i cleaned and pumped the tank clean and got all the

trash out of it, to soon find out that the fuel pump being clooged was the problem, not the

injectors not firing. now yesterday we changed them out for tan injs. that are rebuilt and

the works done to them,because i thought that the purple injs. were red (na injs.) ,being

the reason i wanted to change them to tan 550cc not the na 460cc. then finding out that

they were purple and not red and the fact that they worked was confusing. so i also got

the pigtails replaced that same night and they are soldered just fyi. and also the inj. plug

from the factory harness plugged onto the purple injs. no problem and the new pigtails

plug fine onto the tan injs. point being my car is supposed to have tan injs. but it ran best

on purple injs. both injs. are 195500-1370's just one set purple and the others are tan.

any one understand now why i wanted to change them out..........

i also figured that i would double space this to help readers

 

haha. classic.

hmmmmmmm. that is a very vary odd ball situation isnt. ahh well. put the purple ones back on then. really, if they are working better then sweet as. you never know, the place you got your tan injetors cleanned etc might have fucted them.

 

well i wonder if it has anything to do with me rewiring new pigtails but it shoudnt i did it one wire at a time to keep them right. but i hope i dont have to get a new gasket cause i made that one out of gasket material and it wasnt fun but not hard just time consuming. but i guess ill put the purples back in and see whats up, but aslong as someone else sees this as a weird situation

 

so just a follow up on my injector problem..
the problem of them not working, well that is not the case anymore. the other day i got pissed off and floored it they worked and has worked fine since so dont understand and guess i wont but i thought i would atleast do the follow up so the interested people wondering the same things i was.

 

maybe there was some air trapped in the line or ome grit blocking the injector??? who knows. Goos to hear your up and runing again

 

thx and it creeps to 8.6 ish lbs is that fine for factory motor well it hits fuel cut in 4th and 5th gear sometimes 3rd
