what injector is a 96

[dohc v6]

I am putting my car back together and I switched up the injectors. Ones from a 94 and ones a 96.

 

[rockfangd]

i believe the bottom is 96 and the top is 94

[5speedz34]

Yeah, that would be my guess to.

[97loudcut]

Top looks older, so I am guessing it's a '94

[dohc v6]

So the darker one is a 94.

Edit: The '94 injector in the same catalog is almost exactly the same picture with number: 217262 as picture of part number: 217304 ('96) at rockauto.com. Tried to be of assistance, but I got nothin'

I don't see a difference other than a little darker on the top and the bottom o-ring is a little different. However, if you look closely around the top of that injector, it looks like a part number of some sort. That might be your tell-tale sign.

 

Good luck!!!

GM liked to color key the injectors with OBD2 96+. Can you read the part #'s stamped on them?

[dohc v6]

Yeah one injector has two color coded rings on it and the other only has one.

[5speedz34]

Yeah, the bottom one is a 96 like I said before.

[dohc v6]

As far as bottom, do you mean the one with orange or black o-rings. I could have sworn that the 96 ones were the black o-rings

Can't go by the o-rings. It is the marker rings. The white one then the orange and green one. Did you get to look at the top of the injector? If you look at the pictures I posted up, they both have numbers stamped into the top of the fuel injector body. If you can get those numbers, there is a way to cross-reference just about anything with numbers.

The injector's Lb/hr flow rate difference should be negligable since they are both a Multec style I injector, as long as it came from the same motor application, you should be fine.... All injectors are controlled the same way as far as how they deistribute fuel, whether it be OBDI or OBDII, SFI, or MPFI, the pcm still Pulse width modulatres them, either one is fine to use, check them for resistance to see which one is actually in spec, normally on Peak and hold systems they will be 1-2 OHMS, and on saturated switch they will be 12-16 OHMS.

 

Warning though the 3.4 "X" motor used a very specialized Multec I injector which sprayed a four way stream.

[dohc v6]

This is a 94 with SFI. I will shoot up the numbers on the tops of the injectors tonight. THanks guyes

Bad

can you please explain what this means.

 

 

"normally on Peak and hold systems they will be 1-2 OHMS, and on saturated switch they will be 12-16 OHMS."

Ron, this link covers the different fuel injectors mentioned above.

Thanks for the link.

 

It would be nice to know the inductance as well as the resistance for testing purposes.

 

[badassoldspower]

Well, I have all my ASEP STG books in front of me, what exactly do you want to know?

[ron350]

What is the resistance and inductance on GM injector # 24503229 same as AC Delco 217-318?

The darker one is the earlier. The lighter one is the 96. What year and OBD are you going to run them on?
