Time to replace injectors

[key_on]

Looks like I've milked the original injectors as long as I can. Seems one of the secondary injectors has died a quick death. I'm planning to use the Accel injectors since others seem to have good luck with them. I also plan to replace plugs and plug wires while I'm that far into it. Planning to use GM wires and plugs.

Aside from ordering o-rings for the injectors and new plenum gaskets, is there anything else I should need in the way of parts to do this job? I've looked at the procedure for R&R of the plenum. Are there any tips/tricks for the R&R of the injectors?

Nothing exciting.

I'd recomend the NGK iridium plugs over the GM ones. Also plan on doing a little cleaning in the "V" of the block.

Thanks for the link Jeff. The pictures are helpful. Can't wait to get this done. I really miss my secondaries.

Coils are not that expensive & they live under there also. Just a thought.:o

I used the Accel's (got 'em from Summit Racing) and am happy with them. You don't need other o-rings. The one that came with the new injectors are working fine. Just make sure to use the correct slot (check out this thread) (http://www.zr1netregistry.com/forum/showthread.php?t=3486).

As in stock GM '90 injectors? FWIW, if you decide to still go GM, the '93-95 injectors would be a better idea.

Wow guys Jeffvette back me up here do not put Stock GM injectors back in they cant handle the additives in the fuel these days. GO with RCs and do this job once or give the Accels a try. Wow bad idea :thumbsdo:

The '93+ injectors are rated to handle up to 10% ethanol. This is the same as any other injector on the market.

I didnt need the o-rings on my 92.

I used the Accel injectors.

I was in a bind (few hundred miles away from home in bg) with several bad injectors so I went with what I have....next time is RC
