just installed neons and???

[Metlic53]

Just put my neon injectors into my 90 model cherokee renix. i know i got the right injectors, their the 703 number. after install it sounds like its running like a stock car, missing alot, alot of hesitating, barely running, as if one of the injectors isnt plugged in. any suggestions? and its smoking alot

Black smoke? If so it sounds like its running real rich for some reason.

did you try to reset the computer ? (I don;t know I just read that answer from thime to time lol)
I am interested because I have read that this mod gives a little benefits and I keep that in mind for things to do

[Metlic53]

yeah its kinda black and blue, it smells rich. Pressure regulator not working right maybe?

you can reset a computer on a 90?

Did you mess with the regulator any, don't see why it would mess up now.

from that thread yes.... I don;t know if it is true but I still do that anytime I change something

well, the o ring for the regulator started leaking so i put a new one on and where that metal line that runs into the regulator it has o rings in there and they fell out so i put them back in, there were 3, but i doubt that has anythin to do with it. and whatever that little plastic piece was on the end of the pressure regulator/metal hose thing broke in half when i pulled it out. did that plastic piece do anythin?

[bigjim350]

Well I guess re-useing the old o-rings on the fuel pressure reg, could have caused some problems, also I think the plastic clip is what holds the fuel line in the regulator.

Never reuse O rings Always use new ones. Reusing them will cause them to leak

I would put the original injectors back in and see if the problem goes away. I suspect you do not have the right injectors for your engine.

well i made sure i got the neons with the correct part number 0280155703. that is what is stamped on the injector, a guy had them on his 98 cherokee i bought from him, he was parting it out. This sheet tells me i have the correct injector, i believe i messed my regulator up, its dumping wayy too much gas in the motor, im going to get a new regulator. if that fails then i'll put the old injectors back in. I've got 2 jeeps so this one can sit for a few days :D

Did you replace the fuel rail mentioned on the sheet?

[Metlic53]

Did you replace the fuel rail mentioned on the sheet?

i did option one not option 2. on option one you dont have to replace the rail. option 2 you have to replace the rail for the ford injectors. i went the easy route.
