csfi need to replace

[ritz93]

anybody know where i can pick up the csfi injector for a 1996 s10 blazer 4.3 vortec VIN W. besides GM?

[SWEATBREAD]

Yes, Napa Auto Parts. Part # Crb 218634

[BlazerLT]

You sure you need to install a new one?

How do you know? They don't fail on the 1996.

I would not replace it with another CSFI unit, I'd get the MFI replacement from GM. About $200 plus S&H online. Part numbers are 12568332 MFI Spider assembly: 88894355 Bracket(can reuse old one): 17113215 seal kit. These part numbers are for a V6

my mec. said she was misfiring on cycl. no. 6, i bought it in to him because it had a realy rough idle and very hard to start. he told me it was the injectors. you said the dont fail on the 96 but i thought iread some of the same problems on 96 and up. on this site.

would you suggest something different? i'm all ears

[BlazerLT]

I suggest you replace the poppet valve going to the 6th cylinder then, not the whole unit.

Have you done a tuneup or anything?

Are you getting any check engine codes?

[ritz93]

just cahnge that one line to the 6th cylinder?
i was going to change the fuel regulator as well. i got engine codes when my mech. scanned it, i had brought it in for a tune up. he changed thing , the idle got a little better but not much. the check engine light comes on and flashes at idle. i thought it was better to change the whole unit, but i know they sell the poppet valves alone for around 80 bucks your probably right. i was concrened with other ones being or going bad.

[BlazerLT]

You need to ask your mechanic what the codes were.

Do you know them?

Not the description, the actual numbers.

[ritz93]

i'll have to ask him what the codes were, i thought i had them writen down. the ticket he gave doesn't have the codes on it, he only wrote problem with fuel injector.

[BlazerLT]

And that is why I would be suspecting his diagnosis.

[ritz93]

do you think he's full of it? and that not be the problem?????

[BlazerLT]

Well, It might be, but I am not liking the lack of details in his synopsis.

Too general.

Get the exact codes and we can go from there.

[ritz93]

you got it get back to you tomorrow,
thanks

[BlazerLT]

BTW, have you taken off the EGR valve and checked for chunks of carbon?

[ritz93]

yes took it off, it was fine moved easy didnt look too bad.
