He guys,
I am thinking of getting a 90 300 ZX na and the seller says it has #6 fuel inj. is bad...

Some research seems to say this is one pain of a job...

I changed a fuel inj on a old 240 SX, no big issues there, but it looks like this job is...

Anyone do it?

I believe the whole upper plenum needs to be removed. If that's the case: PITA!

lol I've heard it's a bitch too man, but I think we can all agree that the zed to 240sx poonanie attractor ratio is like 20/1 ...

You do have and make a major point there...I concure!

:D I knew you would :thumbsup:

i have personaly changed an injector on my Z.....and YES, it is a major pain. so many vaccuum lines and electrical connectors to disconnect on the plenum, and you cant even see half of them. my plenum was sitting half-way off for about 2 hours because i tried taking it off after i thought i was done taking all the hoses off, but noooooo, there was still more hoses connected.

^ So you have to remove the whole plenum, right? ^

yeah.

Ouch. Sucks.

well, you supposedly can grind a little bit off the plenum and get to the screws, but i dont like the fact of grinding into my plenum.

Yuh... that sounds kind Mickey-Moused.

^ I agree, I'd be to scared to fuck something up, but I don't like the overall idea of the action either

^ Mr. Motivation! ^

Yeah.. that would suck if you grinded a little too deep.

"GRRrrRrRrrrrrrrrind-Craaaaaack! OH-FUCK!"

hey via, where in cali do you live...???

So.Cal.

About 70-some miles North of LA in the Desert. Why? Wanna come visit me?

lol I'm gonna' be in san diego over new years time... wanna go par-tay?

Hahaha! What a Noob! I'm going to Vegas, B-Yatch!

i recommend anyone that is going to do some serious modding or upgrading on a Z32 to do that grinding down of the plenum. this will make your life alot easier when you have a fuel injector fail. i will be doing this with my new motor and i will also be putting GM plugs snap'n'pull wiring harnesses.

i will explain this later. i have learned alot of little tricks from research over the last couple of months. i will share with you guys once i work out all of the details.

Hmm... I hope you have another write-up coming along, Jason. Chop-Chop.

:lol:

$10??? my time is worth more money than that! :D

Yeah... Removing the Upper Plenum with the engine in the car SUCKS ASS. I'd recommend pulling the engine, and replacing the gaskets, if you're tearing into it anyway.
