One injector shorts out all ?
Driving down the freeway today, I jump on it, to get around a slow moving bozo and stall (now I'm 75 mi from home). I get it off the freeway it starts and dies and then will not start ... getting gas and spark. Tow it to a dealership for a diagnostic,get a loaner, and they call and say #1 injector is shorted and is shorting the rest out. That the car will run when #1 is unhooked ! O yea they want to change all for $1600.00
Input please !! 89 vert :confused: [B]

If that includes installing all new injectors it doesn't sound bad for dealer service. I would guess they are charging $150/injector.

Yikes, that price is insane! If you happen to need new injectors you can get them for less then 300 for the whole set. And I saw someone recently even most a set of 8 for $99!

Oh, well since you can wrench on your car, for one injector you might try Contemporary Corvette or Cruzin Performance. Both links are on my site.

Wher can I get the 99.00 injectors and I'll disconnect the bad injector and drive it home for the fix.

That is exactly what happened to my wife's 89 Beretta. It would just stall for no reason, sometimes at 70 mph on the freeway, sometimes sitting at stop lights. We had it into several shops and nobody could diagnose it. After puting up with it for many months, it finally got to where it would not run at all. I finally took it to a dealer and one injector was shorting out and killing all of them. I paid them $60 for their time (their bill for diagnosis), unplugged the bad injector to drive it home, and replaced it myself.

Re: One injector shorts out all ? (ojaijim)
i hope they include the lube for $1600!!! thats obscene...if you have the time and understanding, do it yourself...i can't imagine it will cost you more than $350 in injectors and new gaskets. a friend and I just rebuilt my 85's L98 top to bottom and it wasn't even CLOSE to $1600. in fact...it was about half that (i haven't had the heart to add it all up yet :leaving: ) one thing i would question is whether one bad injector would short out all 8, or just one bank, because, at least for mine, there are 2 different sets of wires that go to the fuse box and to the ECM. and hopefully is it simply a bad injector and not a gremlin in the wiring. good luck and keep us posted. :thumbs:

The L98 is a batch-fire system with all the injectors in one bank wired together; so if one shorts it prevents proper voltage across the others.
Pull the connector off the bad one, drive it home, then check all injectors with an ohm-meter. Should be 13-16 ohms; below 11 ohms is really bad.
89 Vette's had 22lb/hr injectors; if you need 1 or 2 give me your address and I can send them.

To put it into different terms, batch fire means that the injectors are wired in parallel. If you short across one, all of the voltage takes that route and none of the other injectors get anything, so you take out that whole bank because the good injectors aren't firing, and the bad injector is bad so it can't fire...
I wouldn't change just one...I think I paid $289 for my 24lb/hr Accel injectors...but Accel sucks so go with a different company.
